摘要:
This invention relates to a process for the simultaneous coproduction of ethyl acetate and isopropyl acetate. The esterification reaction comprises contacting acetic acid with a mixed alcohol stream of ethanol and isopropanol. Exemplified is a purified, Fischer Tropsch derived mixture of ethanol and isopropanol. The esterification reaction occurs in the presence of an acidic catalyst in a liquid phase reaction system. The resultant crude reaction step product is separated and purified by distillation to produce acetate ester products having greater than 99.5 wt% purity.
