摘要

To the points made by the authors of Ref. [1] in their discussion of the possible superiority of ethanol over methanol in esterifica-tion of biodiesels I wish to add the following.rnIt has been noted in this journal [2-4] that when methanol is the reagent used in esterification there is loss of some of the carbon neutrality if, as is highly probable, the methanol has been made from natural gas or from coal via synthesis gas. The acids in biodiesel are typically C_(18). Such an acid esterified with methanol becomes C_(19) and the loss of carbon neutrality is (1/19) ≈ 5%. Ethanol on the other hand is almost certain to have been made by fermentation and is carbon neutral. A C_(18) acid becomes, if esterified with ethanol, a totally carbon neutral C_(20) molecule.
