3 Biodiesel Titrations

Once you have your titration solution ready its now time to start doing the titration. Remember on the board we explained how to do it. Were basically going to take a known amount of the base solution. This is our .1 percent base solution and Im gonna pour some of this out into a little cup. Its important that you never draw any of this with a syringe because it can contaminate this. Thats always why I put a little bit in a little cup. Seal it right back up and that way I have a vessel for doing it. Now I also have isopropyl alcohol this is 91 and Im gonna put this in a vessel as well so that I dont contaminate it either. To do a titration you have a sample of oil that you dont know the acidity of and youre gonna get a syringe and youre gonna suck up 1 milliliter of oil. These have milliliter markings on the side. These are kind of a handy little set of syringes. They actually say oil alcohol and titration solution. If youd like these I carry them on my site as well at utahbio but any syringe will do but I just like it so I dont mess up my syringes. Im gonna suck up a milliliter of oil. I usually go a over and then I come back down. Im gonna move it I have a bubble on top that I want to get rid of. Im gonna squirt down till I get to a milliliter of oil. Ive got a milliliter of oil there. Before I put that into my solution here Im going to put 10 milliliters of isopropyl alcohol in here. Now these actually have handy measurements on the side so I can actually do it that way but if you dont you can suck up ten milliliters with a syringe and get rid of your bubble. This is somewhat of a messy process so you want to wear gloves. Youll notice that I have a little bit of oil and stuff around. Theres just no clean way to do biodiesel. I have yet to meet anyone who has. Buy some kitty litter if you want to make sure things are clean as the oil dries. Kay so Im gonna put ten milliliters of isopropyl alcohol into my jar here and Im gonna spray a milliliter of oil into this mixture. Now let the camera get up and kinda look at that real close. Now youll notice that is not really well mixed and thats because oil and water dont like each other so were gonna have to mix this up here. Well stir this here for a second. If youd like you can heat the mixture a little bit. You dont want to heat it too much cause you dont want to boil of your alcohol but Ive heard of some people heating the oil in the microwave in a little tiny dish before they use it. Our goal was just to basically get it to be one solution as you see here. To this mixture were now gonna add about 3 or 4 drops of our phenolphalene. Again this is just a PH indicator its nothing more than that. Its not really important how many drops you need to put in here cause all this is doing is indicating PH. Kay so Im gonna mix this up. Now what Im gonna do is very slowly suck up some titration solution. Ive got ten milliliters of titration solution in this syringe. Im using a little stirrer and Im just gonna start stirring this in. So I started with ten. Im basically just looking for this to change colors. I dont know if you can see that real well. Let me see if I can get you a closer view. As I put this in it is literally starting to change color drop by drop. You see that pink thats occurring? Lets see if I can do it a little differently here. That pink is my indicator solution. Whats going on is Ive got a basic solution Ive got an unknown amount of acid and its starting to neutralize that acid and taking the pH up over. How you know when youre done is when that turns pink and stays pink for about 30 seconds. There were starting to come into it. There were a nice pink. Just a little bit more to be sure and then well sit and let that go for about 30 seconds. After 30 seconds if it is still that color then were gonna write that number down. Im gonna let this sit here while we look at our math. We started with ten milliliters and were now at seven so 8910 thats three it took 3 milliliters of our titration solution to neutralize this acid in our oil. Youll notice were staying this nice beautiful pink which is what were after there. A lot of times when youre doing a titration its important to do it about three times to make sure that youve done it right. So were gonna do it Im gonna show you how to do it again one more time. cause we kind of slopped around and made a little bit of a mess. You just want to make sure you always redo it doublecheck your math. If after three times your number are plus or minus one thats your number. Average them out and thats gonna be your titration number. So well go ahead and pause here for a moment and well get another one set up.

Kay weve done our first titration and we got three so were gonna do another one. Again one milliliter of oil. So Ive got one milliliter of oil. Set that here. Im gonna put ten milliliters of alcohol. Get that bubble out of the way. Ten milliliters of isopropyl alcohol into a container. One milliliter of oil. A couple of drops of my titrating solution. Again this is phenolphalene phenol red or toomric will work just fine. It also doesnt matter how much of this I put in because its just my indicator solution. Now Im gonna mix this up and get a really uniform batch of oil alcohol and the indicator solution and then using my titration solution remember known amount of base unknown amount of acid in we go. Well move these out of the way so we get a little better view here. Slowly Im just gonna start adding known amounts of base starting at ten. Well swirl it around it already started to turn a little bit pink which is what we want. Theres some pink and back to yellow so we need a little bit more. Swirl it around. Oh its getting there. Notice its staying this good nice pink color. Maybe just a little bit more. Okay here so Ive got that beautiful pink color. Phenol red turns sort of a redish color. Tumric turns kind of a pinkish color. This is phenolphalene you can see that its somewhat of a pink color but your goal is just to hit that color and make it stay for about 30 seconds. Again what that means is Ive had an unknown amount of acid in the oil a known amount of base that we add to it until we knock that pH until weve neutralized it. This took this is sitting at six this time. So were really close. Well do one more and then well average everything together then well show you how much youre gonna need to make a batch.

Kay well do our third and final titration. Again were gonna do ten milliliters of alcohol. Well drop some indicator solution one milliliter of oil put it in mix it up and then were gonna slowly add in our titration solution. Were gonna watch for the color change. Mix it around its starting to turn. Its getting there and we changed. Im at six so I know add a little bit more just to keep it there. So my first one was seven my second was six and my third one is about six and a quarter so Im gonna call this about six grams or six milliliters extra. So what our titration would be or how much we would add to our biodiesel that were gonna make were gonna take 7.5 4 so about 12 grams we will add per liter of oil. So if we had 100 liters of oil we would add 1200 grams of catalyst to that into our methanol to make biodiesel. And thats how you do a titration.

You And Your Morocycles Safety

If you decided to buy a motorcycle you need some accessoriesso here is my advcie about the best gadgets you can get to have a better ride and to protect yourself.

Motor cycle boots should be stiff in order to provide protection but not too much so. First you need an insurance. Motorcycle insurance quotes help you estimate the available insurance options for your bike. We can choose insurance policies either through insurance agents or online.

Also you need protective gear: Motorcycle pants come in many variations. Regular motorcycle pants are like normal pants only that they give extra protection especially on the butt. Motorcycle boots come in different colors and designs to fit your mood and lifestyle. However it is wise to choose a design that’s not only based on appearance but also on durability and safety features.

Choosing motorcycle boots apparel can be a tough task. The perfect motorcycle boots apparel needs to have certain qualities and sometimes you don’t want to sacrifice anything making it harder to find the right boots. Choosing motorcycle boots with thick rubber soles will help absorb vibration from the motorcycle that can cause foot and leg pain. A deep tread pattern is essential for traction and stability.

Motorcycle saddlebags are far more advanced and high tech than the sacks used on horses. At an average speed that a motorcycle travels it required a secure and convenient mean of carrying the rider’s belongings. Motorcycle tires are oftentimes misunderstood. This is a saddening fact.

Helmets protectors and boots also available as add ons. Find packages for your street bike apparel dirt bike and off road motocross MX and cruiser gear for your Harely Davidson!! Helmet must make you feel safe yet comfy. You can have the fiberglas shell helmet if you want your helmet to be highimpact resistant and durable. Helmets are key in keeping safe the fragile bones in the head. What we need to teach our children is to prepare for the unexpected.

Leather can lasts up to 30 years. Through the years it has already established an attitude and traditional beat. Leather over the years has proven to be the best material for motorcycle clothing. It is resistant to tear naturally warm and acts as the first defense by coming between the biker and the rough asphalt road. Leather jackets and the fabric on textile jackets protect a motorcycle rider’s skin from road rash with the aid of body armor inserts. There are many types of motorcycle jackets and helmets to choose from.

Leather motorcycle boots with thick flexible uppers provide much better protection against road debris and hot exhaust pipes. Frye boots is just one manufacturer that produces these kinds of quality engineer boots.

Goggles are a great way to protect the eyes without having the heaviness of a helmet. You won’t have any protection for your head though when you just have goggles on. Goggles don’t do much for your head in an accident but you will at least be able to see the road when you are taking that favorite ride around town.

Yamaha – Yzf – R15

Features:

Liquidcooled engines provide steady performance lessen vibrations and offer a high quality ride. A liquidcooled engine does not need heatdissipating fins and therefore the engine is able to bring its best performance without being affected by temperature. Additionally because the head and cylinder are enclosed in a water jacket mechanical noise from the engine is reduced noticeably. The newly developed engine delivers agile riding performance and dazzling performance on straight stretches of road as well as on winding roads.

The frame which forms the basis for riding comfort and handling performance is a Deltabox frame which delivers superior rigidity equilibrium.

It is equipped with a linked type monocross suspension that delivers a comfortable ride and a cushioning performance that is less prone to bottoming out. In particular it reduces annoying ‘sinking’ when riding tandem.

This characteristic of motorcycles designed by YAMAHA as represented by the R series reflects the philosophy running through these models expressing performance visually. Viewed from the side the shape created by the side panel and the upper surface of the tank creates an impression of the center of gravity shifting to the front tyre. This is a visual representation of how the front tyre grips the road in its sporty running performance. Needless to say YZFR1 with its athletic build is also a visual expression of performance. A characteristic of the R series is that when you view the machine you get a sense of its concept and performance.

When viewed from the front it gives a sense of volume that seems well beyond its 150cc displacement. This does not simply mean that it is huge but that it is grounded in the Art of Engineering which transforms function into art.

YAMAHA?s Humachine Technology involves studying the form of the motorcycle actually in motion with the rider on it. The R series is the embodiment of 1 wide frontal space that protects the rider 2 easy to ride seating area that gives riders the freedom of movement and allows them to steer effectively 3 the glamorous tail treatment that takes into account the management of airflow behind the rider and 4 a sexy racing form that brings all 3 of these elements together in a harmonious package. These characteristics have been splendidly reproduced in YZFR15.
