Device and method for synthesizing cyclohexanol from cyclohexene

The invention discloses a device and a method for synthesizing cyclohexanol from cyclohexene. The device comprises a reactor, a catalytic distillation tower, a hydrolysis tower and a fractionating tower which are connected in sequence. The method comprises the following steps: carrying out a pre-reaction on cyclohexene and organic acid in the reactor, and carrying out a catalytic distillation reaction in the catalytic distillation tower to obtain a heavy component containing organic acid cyclohexyl ester; hydrolyzing the heavy component of the organic acid cyclohexyl ester to obtain cyclohexanol and a light component containing an aqueous organic acid solution; and fractionating the light component containing the aqueous organic acid solution to obtain the organic acid. The device and themethod are high in cyclohexene conversion rate, high in cyclohexanol yield and low in equipment and operation cost. 本发明公开了一种环己烯合成环己醇的装置和方法，包括依次连接的反应器、催化蒸馏塔、水解塔、分馏塔；环己烯和有机酸在反应器中进行预反应、在催化蒸馏塔中进行催化蒸馏反应得到含有有机酸环己酯的重组分；有机酸环己酯的重组分经水解
