Method for inhibiting by-product cyclododecane methanol in cyclododecanol hydrogenation preparation process

The invention provides a method for inhibiting a byproduct cyclododecane methanol in a cyclododecanol hydrogenation preparation process, which comprises the following steps: adding one or more of cyclododecanone, epoxy cyclododecadiene, epoxy cyclododecene and epoxy cyclododecane and a catalyst into a reactor for reaction; and converting into cyclododecanol at a certain reaction temperature and pressure. According to the method for inhibiting the by-product cyclododecane methanol in the cyclododecanol hydrogenation preparation process, the catalyst is suitable for one or more of cyclododecanone, epoxy cyclododecadiene, epoxy cyclododecene and epoxy cyclododecane, and the product can be suitable for high-purity downstream products; the purity of a rectification separation product is greater than 99.95%. 本发明提供了一种抑制环十二醇加氢制备工艺中副产物环十二烷甲醇的方法，将环十二酮、环氧环十二碳二烯、环氧环十二碳烯、环氧环十二烷其中一种或者多种组分和催化剂加入反应器内进行反应，在一定的反应温度、压力下转化为环十二醇。本发明所述的一种抑制环十二醇加氢制备工艺中副产物环十二烷甲醇的方法,本技术发明催化剂适用于环十二酮、环氧环十二碳二烯、环氧环十二碳烯、环氧环十二烷其中一种或者多种组分，产品可以适用于高纯下游产物，精馏分离
