| Abstract: | Cyclohexanone glycol ketal(CHGK) was synthesized from cyclohexanone and ethylene glycol in the presence of manganese chloride tetrahydrate (MnCl2·4H2O) catalyst. The optimum condition was obtained as follows: cyclohexanone-to-ethylene-glycol molar ratio = 1.0∶1.7, m(MnCl2·4H2O) = 12% of total mass of cyclohexanone and ethylene glycol, and reaction time 2.5 h. GHGK yield of 82.8% was obtained under the optimum reaction condition. |
