减压树脂催化缩合制备2－（1－环己烯基）环己酮的方法
摘要：
本发明涉及一种减压树脂催化缩合制备2－(1－环己烯基)环己酮的方法其特征是，环己酮在酸性或碱性离子交换树脂催化下，采用缩合双套管常减压连续催化反应及分离装置，通过减压控制反应温度，反应温度维持在50－90℃之间，进行催化缩合反应，控制负压在50cmHg～75cmHg，经精馏得到二聚体2－(1－环己烯基)环己酮。本发明反应速度快，操作方便，分离简单，副产物少，生产成本低。
摘要（英）：

The present invention relates to a method for preparing 2-(1-cyclohexenyl) cyclohexanone by means of reduced resin catalytic condensation. Under the catalysis of acidic or basic ion exchange resin said invention adopts condensation double-sleeve convertional pressure-reduced continuous catalytic reaction and separation equipment to make cyclohexaone undergo the process of reduced catalytic condensation, and utilizes pressure reduction to control reaction temp. and make reaction temp. be 50-90 deg.C, and makes catalytic condensation reaction and controls negative pressure in 50 cmHg-75 cmHg, then adopts rectification process to obtain dimer 2-(1-cyclohexenyl) cyclohexanone. The invention is quick in reaction speed, convenient for operation, simple in separation, small in by-product and low in product cost.
