ABSTRACT:
Esters are formed by reaction of acetic anhydride with tertiary butyl or tertiary anyl alcohol in the presence of tertiary amine catalyst such as DMAP or NMI catalyst and acetic acid in amount sufficient to present catalyst degradation; in preferred practice a mixed acetic anhydride and acetic acid stream is recycled to the esterfication.
