摘要

Liquid-phase catalytic hydrogenation of 1, 4-cyclohexanedione was carried out by using various metal catalysts on SiOz (Ni, Cu, Pd, Pt, Ir, Ru) in 2-propanol as solvent under low hydrogen pressure, 6.2 bar, and 20 “C. A kinetically consecutive process, diketone-ketol- diol, is obtained, and 4-hydroxycyclohexanone may be obtained in a single step at a yield of 70% by utilizing Ru/SiOz. The rate and the selectivity for the first step of the reaction giving ...
