Provided is an industrially superior method for producing cyclohexyl alkyl ketones, which solves the problems in process reduction and in disposal of wastes such as metals.
An aromatic ketone represented by a formula (1) is nuclear-hydrogenated with pressurized hydrogen and in the presence of a solvent at a temperature of from 20 to 120° C., in the presence of a catalyst that carries from 0.1 to 20% by weight of a ruthenium atom on the carrier, thereby producing a cyclohexyl alkyl ketone represented by a formula (2): provided that, in the formula (2), n indicates an integer of from 1 to 3; R represents a hydroxyl group, a cyclohexyl group, an alkyl group having from 1 to 4 carbon atoms, or an acyl group having from 1 to 4 carbon atoms
提供了一种在工业上优越的生产环己基烷基酮的方法,解决了在过程减少和处理废物(如金属)方面的问题。通过在20至120°C的温度下,在有溶剂存在的情况下使用加压氢气进行核氢化,存在携带从0.1到20%重量的钌原子的催化剂,从而产生一个由式(2)表示的环己基烷基酮:其中,在式(2)中,n表示1到3之间的整数;R代表一个羟基、一个环己基、一个含有1至4个碳原子的烷基或一个含有1至4个碳原子的酰基。
