ABSTRACT:
A method for producing a lower alkyl acetate in which undesirable polymerization of the starting material of olefin and deterioration of catalyst can be avoided, a higher catalytic efficiency and a higher reaction rate are attained, the installation of reaction equipment is inexpensive and the operation of the reaction can be carried out without difficulty. The method of the invention comprises the steps of feeding acetic acid and an olefin both in a liquid state and in cocurrent through a continuous flow type fixed bed reactor containing an acidic ion exchange resin catalyst(s) under the conditions that the molar ratio of acetic acid to the olefin in a feed current is in the range of 1.0 to 2.0 and an LHSV of acetic acid relative to the catalyst layer is 0.1 to 10.0 with maintaining the inlet of the catalyst bed at 70.degree. C. to 120.degree. C.; cooling the obtained reaction mixture to a temperature not lower than 70.degree. C.; and recycling it to the catalyst bed.
