摘要
本文主要研究了H酸在不同pH条件下与对甲苯磺酰氯缩合酰化效果,探讨了此反应的相关机理,并重点考察了酰化液中的H酸残留对合成染料C.I.酸性红249的影响。
H-acid was acylated with 4-methylbenzenesulfonyl chloride by condensation in different pH conditions. The mechanism of the reaction was studied. The effect of H-acid in the acylation solution on synthesis of C. I. Acid Red 249 was investigated.
