PURPOSE:To advantageously obtain the title compound by feeding acetic acid and linear butene both in a liquid state to a specific catalytic layer of a continuous circulation type fixed bed reactor in a counter flow under a specific condition and recycling the reaction mixture to the catalytic layer at a specific temperature at a specific ratio. CONSTITUTION:A continuous circulation type fixed bed reactor 2 having a catalytic layer 3 packed with a styrene-based (and/or phenol)sulfonic acid type ion exchange resin catalyst wherein an inlet temperature of the catalytic layer is maintained at 80-120 deg.C is charged with acetic acid and linear butene both in a liquid state in a counter flow under conditions of a molar ratio A of acetic acid/linear butene in a feed flow 1 of 1.0-2.0 and LHSV based on the catalytic layer 3 of acetic acid of 0.1-1.0 and the prepared reaction mixture is cooled to >=70 deg.C, is circulated through an inlet of circulation flow 4 to the catalytic layer 3 in a ratio shown by the formula (X is weight ratio of circulation flow rate/feed flow rate) to give the title compound useful as a solvent, perfume, etc., by using an inexpensive reactor by a liquid-phase reaction efficiently and in readily temperature control in a reaction zone, in high linear butene conversion ratio and high productivity. |
