I've read quite a number of things referring to deterioration of rubber and certain plastics by biodiesel. How serious is this problem really? I understand that methyl ester is a pretty good solvent. I know that methanol is a really good solvent. In Aleks Kac's "Foolproof method," section on methanol recovery, he says that you can remove at least one quarter of all the methanol used. Over 50ml per litre of oil. My questions are: 1) Is this much unreacted methanol present in the other biodiesel recipe's or is this unique to Aleks' "foolproof" one.? 2) Is it mainly the methanol which causes the deterioration, or is the methyl ester equally or more to blame. (will a good methanol recovery system help signifigantly to save rubber etc.?)
Obviously this problem isn't critical, because plenty of you folks are driving on the stuff, but I'd like to understand this aspect a little better. Thanks, Dave. Do you Yahoo!? Yahoo!
