Abstract
The present invention provides a process for the preparation of ethyl acetate by hydrogenating acetic anhydride, or mixtures of acetic anhydride and ethylidene diacetate, in the presence of a Raney nickel catalyst and an organic sulfonic acid to produce ethyl acetate.
Claims13
A process for the preparation of ethyl acetate which comprises hydrogenating acetic anhydride or a mixture thereof with ethylidene diacetate at a pressure of about 3000 to 35000 kPa and a temperature of about 100.degree. to 250.degree. C. in the presence of a catalytic amount of a catalyst system comprising Raney nickel and an organic sulfonic acid.
A process for the preparation of ethyl acetate which comprises hydrogenating a mixture of acetic anhydride and ethylidene diacetate at a pressure of about 3000 to 35000 kPa and a temperature of about 100.degree. to 250.degree. C. in the presence of a catalyst system comprising Raney nickel and an organic sulfonic acid.
A process for the preparation of ethyl acetate which comprises hydrogenating a mixture of acetic anhydride and ethylidene diacetate at a pressure of 3,000 to 20,000 kPa and a temperature of 130.degree. to 180.degree. C. in the presence of a catalyst system comprising 0.1 to 10 weight percent of Raney nickel and 0.1 to 3 weight percent of an organic sulfonic acid selected from methanesulfonic acid, p-toluenesulfonic acid, or a mixture thereof, the weight percentages being based upon the total weight of acetic anhydride and ethylidene diacetate.
