Greg H. asks: >In making Biodiesel, if someone uses methanol, it does not have to be >water free, but if you use ethanol, it has to be water free correct?
To be totally exact, neither of them has to be water-free. It's just that methanol, being a much stronger acid than ethanol, is less sensitive to water. (ie, it makes methoxide much more readily than ethanol makes ethoxide). Methanol can have a few percent of water and still work, whereas ethanol should have no more than a few tenths of a percent. By using a combination of ethanol and methanol, you can achieve a level of water-sensitivity somewhere between the two. ------------------------ Yahoo!
