摘要
Abstract
Using strongly acidic cation exchange resin as catalyst,p -methoxyacetophenone cyclo ethylene glycol ketal was synthesized by the reaction of p - methoxyacetophenone and ethylene glycol.Effects of kind and dosage of water striping agent, molar ratio of the raw materials, dosage of the catalyst and reaction time as well as the times of reuse of the catalyst on the reaction yield were studied.Experimental results showed that the proper technological conditions were given as follows:n(p -methoxyacetophenone):n( ethylene glycol) =1: 1.3, using cyclohexane as the water striping agent with dosage of 40 mL refers to 0.1 mol of pmethoxyacetophenone and 0.13 mol of ethylene glycol; and dosage of catalyst is 1.5 g; reaction time is 3 h.Yield of product achieves 95.58％ with purity of ＞ 99.0％.The catalyst could be used for not less than 5 times without any treatment.关键词
