| 摘 要： | 以环己酮和乙二醇为原料，硫酸镓为催化剂，在微波辐射和无溶剂条件下，合成了环己酮乙二醇缩酮．探讨了酮醇物质的量比、催化剂用量、微波功率和辐射时间对产品收率的影响．结果表明，环己酮乙二醇缩酮的最佳合成条件为：n（环己酮）：n（乙二醇）=1：3，催化剂用量为反应物总质量的2．0％，微波功率为375W，辐射时间为20min．在此条件下，缩酮收率可达96．3％，说明硫酸镓是一种合成环己酮乙二醇缩酮的优良催化剂． |

| Abstract: | Cyclohexanone glycol ketal was synthesized using cyclohexanone and glycol as reactants and gallium sulphate as catalyst without solvent under microwave irradiation.The effects of reactant molar ratio,amount of catalyst,microwave irradiation power,microwave irradiation time on the yield of cyclohexanone glycol ketal were studied.The optimal conditions were as follows:n(cyclohexanone):n(glyco1)=1:3,mass ratio of catalyst to reactant 2.0 %,microwave irradiation power 375 W and radiation time 20 min.Under these conditions,the yield of cyclohexanone glycol ketal could be reach 96.3 %,indicating that gallium sulphate is a good catalyst for the synthesis of cyclohexanone glycol ketal. |
| Keywords: | microwave irradiation gallium sulphate cyclohexanone glycol ketal catalytic synthesis |
