Abstract
Ethyl acetate is produced in good yield by reacting ethylene with acetic acid in the presence of a catalyst comprising a tungstophosphoric acid of which 10-90% of the total amount of proton is replaced with a member selected from the group consisting of (a) cesium metal cation, (b) a combination of cesium metal cation and at least one cation selected from alkali metal cations other than cesium cation, and (c) a combination of cesium metal cation and at least one cation of iron group metal cations.
