Yes. Go to the list website, log in, and change your user settings. List URL: http://groups.yahoo.com/group/biofuel >Q2 Being new to biofuels i would like to ask a question about ethyl esters. > I have read the fool proof article for biodiesel in which the first half >of the reaction is done with sulphuric acid, then the second half is done >with Lye (NaOH) with only half the basic methanol added, glycerine separated >and then second half added. Hm. Brian, I'd read that again if I were you. http://journeytoforever.org/biodiesel_aleksnew.html >My question is has anyone done this Acid/lye reaction with ethanol/KOH >instead of Methanol/NaOH? Would the H2SO4 react badly with the KOH instead >of the NaOH as in the foolproof method? I think you wouldn't have problems with the KOH (use twice as much) but I'm pretty sure you'd foul up with the ethanol. >I just find the use of ethanol more appealing(less dangerous). Not really - in itself maybe, but remember it's not ethanol you're working with, it'd be sodium ethoxide, or if you used KOH potassium ethoxide. But indeed ethanol is more appealing - you can make it yourself, unlike methanol, and it's a renewable, carbon-neutral biofuel, again unlike methanol, most of which is fossil-fuel-derived. But ethyl esters are much more difficult to make than methyl esters. There's a basic method here: Optimization of a Batch Type Ethyl Ester Process http://journeytoforever.org/biofuel_library/ethyl_esters.html Search the list archives for the work Ken Provost has been doing with ethyl esters, very interesting. http://groups.yahoo.com/group/biofuel/messages It has to be absolute ethanol, must be dry. See: http://journeytoforever.org/biodiesel_link.html#ethylester >Q3 Does anyone know how much water is in "methylated spirits"? I thought >it was 95% ethanol and 5% methanol, but water could be in there as well. You should check with the Australian government, I think the requirements may vary from country to country. >If >methylated spirits is less than 1% water, would the combination of methyl >and ethyl alcohol cause any problems with the transesterification process? Again, see Ken Provost's postings. Please let us know how you get on.
