[Biofuel] Titration
Dear all, Need help in this process. I have read about this procedure and followed it exactly as it said in the JTF. I even bought a digital pH meter to make my life easier but this proved otherwise. Putting the pH meter into oil the reading does not stop moving, it take minutes to accertain whether the pH meter has stopped at a correct reading. Thereafter, when we titrate it, the pH meter goes wild again. Is there any better way to read the pH. I think all my titration results is as wild as the pH meter's reading and that will make my process wild as well. I am trying to get the pH reading at 7 +_ 0.5 From what I read, this should not give us too much of a problem. Right? Any other suggestion on this titration process?

[Biofuel] Using plastic pails
Dear all, A quick queston. Is it okay to use plastic pails I find around my house to built the reactor tank, and other tanks for the biodiesel process instead of stainless steel? It is some much cheaper and easier to work with plastics. Will there be unforseen problems with this? Thanks guys. Jeff _ Is your PC infected?

[Biofuel] Biomass to Biodiesel
Dear all, I came across an article regarding an (East) Europe or (old) Rusia company that has been using biomass (wood chippings if not mistaken) for producing Biodiesel for as far as they can remember. Does anyone know the name and location of this company, as I cannot remember where I came across this. Thanks Jeff _ Express yourself instantly with MSN Messenger!

Re: [Biofuel] Quality Test
Jan, Thanks for the tip. We tried it and without stirring, there were clear yellow deposit on the bottom. The biodiesel did not disolve fully in the methanol like you said. So does this mean the next time I do another batch, I have to increase the methanol to the sodium? Any suggestion?

The test method that you are using seems to me highly dubious, since there are a number of pre-assumptions that has to be met. For a further check I´d suggest this: Take exactly 25 ml of biodiesel and dissolve it in exactly 225 ml of methanol in a measuring glass. Now: The biodiesel should be fully soluble in the methanol forming a clear bright phase. If not, there is pollution in the biodiesel causing you trouble with the water test. Each ml of undissolved material is corresponding to 4% by volume. Are there any undissolved material at the bottom of the measuring glass ? If there is, your reaction is not complete and this is causing you trouble with the water test. This method does not cover every aspect of quality, but it gives a hint though Good luck to you Jan Warnqvist AGERATEC AB [EMAIL PROTECTED] + 46 554 201 89 +46 70 499 38 45 - Original Message - From: Jeffrey Tan [EMAIL PROTECTED] To: Biofuel@sustainablelists.org Sent: Thursday, August 11, 2005 2:19 PM Subject: [Biofuel] Quality Test Hello all. Need some explanation and advise here on my experiments please. I have been using virgin cooking palm oil for the experiments. When following the steps for checking on quality, I put in 150ml of de ionised battery water and 150ml of the biodiesel obtained but the end result was clear yellowish liquid on top and white emulsion like on the bottom. I have done 3 different batches with the same result. My further reading and guess is either the NaOH is too much/little or the methanol is too much/little. My next step will probably to increase the methanol from 200ml to 400ml (my batches are in 1 liter of new oil). Any comments or suggestions from the gurus out there?

I tried the world famous chop stick titration technique. Wow what a difference in my titration #. I did a 1 ltr test in a soda bottle, with excellent result almost instantly. But here is where I got into trouble. The next batch was 20 liters I had some methoxide mixed from a prior batch that was also a failure and I couldn't figure what to do with the toxic mix so I tried to dilute it to 10 g.p. liter. I did my mixing of the 20 liters. As it cooled it turned into what looks like lard. I felt that I may have overdosed it. So I then took some test bottles and put 20% failure oil and 75% fresh wvo set it in the sun to melt/ liquefy. (105 deg F) shook it hard also a 50/50 mix in the hot state it seamed to separate better 25/75 than the 50/50 but as the sun went down and it cooled the 25/75 started to jell and the glycerol layer vanished but the 50/50 looked much better with a glycerol layer jelled at the bottom. I m not asking for a fix. But is the jelly a typical sign of over dosing? I have a problem with disposing of the mess I have made if there is a way to salvage it. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Keith Addison Sent: Tuesday, August 02, 2005 8:58 PM To: Biofuel@sustainablelists.org Subject: RE: [Biofuel] RE: Phenolphthalein solution Hi Derick May be there is some help for me out there.

Test strips work ... poorly, if at all, and are not recommended by JtF. but after introducing it to the mix I find if I need to add more solution the color will not change so I need to add strip after strip as I add the solution accuracy is probably off by the time I get done P.H. meter a good one I found to be about the same pH meters work well, especially if it's a good one, you shouldn't be having problems. and I have used phenolphthalein and get excellent response but im no chemist Very few of us are. can anyone tell me how much phenolphthalein to use on the test I have been using 2 drops @ 1% phenolphthalein. The instructions from J.T.F say use 1% phenolphthalein solution (1.0w/v%). If you can please help. Thanks Derick You say: The instructions from J.T.F say use 1% phenolphthalein solution (1.0w/v%). The instructions at JtF say: Add 2 drops of phenolphthalein solution. Dissolve 1 gm of lye in 1 litre of distilled water (0.1% w/v lye solution). In a smaller beaker, dissolve 1 ml of the cooled oil in 10 ml of pure isopropyl alcohol. Warm the beaker gently by standing it in some hot water, stir until all the oil dissolves in the alcohol and turns clear. Add 2 drops of phenolphthalein solution. Using a graduated syringe, add 0.1% lye solution drop by drop to the oil-alcohol-phenolphthalein solution, stirring all the time, until the solution starts to turn pink and stays that way for 10 seconds. -- From: Biodiesel from waste oil http://journeytoforever.org/biodiesel_make.html#biodwvo See also: More about lye How much lye to use?
