ABSTRACT:
This invention relates to a process for the simultaneous co-production of ethyl acetate and n-butyl acetate. The process involves reacting a reaction mixture of ethanol, n-butanol and acetic acid in the liquid phase, in the presence of an acidic catalyst. The process is carried out in a series of reactor and distillation columns. The process is capable of using relatively impure reactants and provides for removing some of the aldehyde type impurities by the use of resin guard beds.
