摘　　要：以二甲氨基氯丙烷盐酸盐和硫脲为原料合成了二甲氨基丙硫醇,将其作为巯基改性剂,对合成双酚A基础树脂催化剂进行了改性,并考察了其助催化效果。结果显示,当巯基改性率为15%时,改性后催化剂丙酮单程转化率达93.63%,较改性前高出30个百分点,双酚A选择性为97.01%,较改性前略有提高。1-Propanethiol,3-（dimethylamino） was synthesized with dimethylaminopropylchloride hydrochloride and sulfocarbamide.The co-catalytic effect of 1-propanethiol,3-（dimethylamino） as mercaptan modifier agent of catalysts for producing bisphenol A resin was also investigated.The results indicates that the single pass conversion of acetone using catalyst with mereaptan modification ratio of 15%,can reaches 93.63% which is 30% higher than unmodified catalyst,and the bisphenol A selection of catalyst with slight increase can reaches 97.01%.
