摘要
本文详细阐述了以环己胺，间苯二酚，硫酸二甲酯，苯酐为主要原料，经缩舍反应，烷基化反应，酰化反应来合成热敏染料TCT-2，并且给出了最佳操作条件：缩合反应：206～208℃，回流反应5小时；烷基化反应：50℃反应2小时；酰化反应：回流反应7小时。
Heat-sensitive dyestuff TVT-2 was prepared by condensation reaction, alkylationreaction, and acylation reaction, using cyclo- hexylamine, resoreinol, dimethyl sulfate and benzoic anhydride as the starting material. Optimum conditions were：condensation reaction temperature 206 ～ 208 ℃, refluxing 5 hrs ; alkylation reaction temperature 50℃ for 2hrs ; acylation reaction was refluxing for 7hrs.
