摘要
以硝酸镧结晶水合物为催化剂、环己酮和乙二醇为原料合成了环己酮乙二醇缩酮,考察各种因素对反应的影响。实验确定较佳反应条件:环己酮0.3 mol,n(环己酮)∶n(乙二醇)=1∶1.5,催化剂用量0.25 g,带水剂甲苯30 mL,反应回流时间2 h,其产品收率达90.0%以上。该方法的优点是环己酮的转化率高,催化剂重复使用性能良好。
Cyclohexanone ethylene ketal was synthesized from cyclohexanone and ethylene using （NO3）3· nH2O as the catalyst. The influences of reaction condition were investigated. The optimum conditions were obtained as follows： 0.3 tool cyelohexanone, n （cyclohexanone） ： n （ethylene） = 1 ： 1.5, catalyst dosage 0,25 g, toluene 30 mL as water-carrying agent, reflux time 2.0 h, with product yield of 93.0% （wt）. The catalyst features high cyclohexanone conversion and repeated usage.
