Isoamyl Alcohol. — The amyl alcohol produced during fermentation was likewise exposed by Elbs and Brunner to the anodic current action in sulphuric-acid solution. It is converted into isovaleric acid with a current yield of about 80%. Some carbonic acid also formed, but isovaleric aldehyde was not present under the chosen conditions. 

The catalytic activity of TPA-PVA-PEG catalyst for the esterification of acetic acid with isoamyl alcohol is presented in Table 1. A high selectivity to the ester was obtained, although traces of 3-methyl-1-butene, 2-methyl-1-butene, and isovaleric aldehyde were...
