Estimating the term…
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.
A process for the simultaneous coproduction of ethyl acetate and isopropyl acetate, comprising reacting an alcohol mixture of ethanol and isopropanol with acetic acid, in the liquid phase, in the presence of an acidic catalyst wherein the reaction is carried out at elevated temperature and at a pressure sufficient to effect esterification of the reactants.
