摘要
通过微波合成法,以对甲苯磺酸为催化剂,由环己酮与乙二醇合成环己酮乙二醇缩酮。考察了微波条件下各因素对反应的影响,得出优惠条件:n(环己酮)∶n(乙二醇)=1∶1.4,对甲苯磺酸为2.5g/mol(以环己酮物质的量计),带水剂环己烷为80mL/mol,辐射功率为90W,辐射时间为13min,产物收率达82.3%。
Ethylene glycol cyclohexane ketal was synthesized under microwave irradiation from cyclohexanone and ethylene glycol in the presence of p-toluene sulphonic acid. The factors that influenced the reaction under microwave heating were investigated, the yield of 82.3% was obtained on condition of ethylene glycol : cyclohexanone = 1.4 : 1 (mol/ mol), p-toluene sulphonic were investigated acid: 2.5 g/mol (based on the amount of cyclohexanone), cyclohexane: 80 ml/mol, irradiation power: 90 W, 13 min.
