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 usedα-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...
