摘　　要：探究了A,A,A-三(4-羟苯基)-1-乙基-4-异丙苯(三酚A)新的合成方法和合成工艺。以α-甲基苯乙烯为原料,经过烷基化、酰基化、酯化、缩合、水解的过程合成出三酚A;并且着重探索了关键步骤以硫酸为催化剂合成三酚A的反应温度、反应时间、酚酮物质的量比、催化剂及助催化剂的用量的反应工艺条件;并且探索了三酚A的精制工艺条件,得到了纯度达到99.872%的电子级三酚A;此方法原料易得,产品纯度高,在工业上容易实施且效率较高。To explore the new method for synthesizing trishydroxyphenylethylisopropylbezene（ TPP） and study on the synthesis process,in this paper,we used α-methyl-styrene as raw materials,and adopted method of alkylation,acylation,esterification,condensation reaction,hydrolysis to obtain the TPP. In addition,we focused on the key steps and used sulfuric acid as the catalyst for TPP and explored the reaction temperature,reaction time,phenol ketone molar ratio,the amount of catalyst and co-catalyst reaction conditions; And explored the TPP＇s purification process conditions to obtain the electronic level,high purity product reaching 99.872%; What＇s more,this method was easily available in raw materials,easy to implement in industrial and high efficiency,high purity,which has yet to see reports at present.
