摘要： 合成了3个含羧甲磺酰基蒽醌染料和相关中间体,并用热重法测出了染料及中间体的脱羧温度.结果表明,将羧甲磷酰基间接地连在苯环上可以降低脱羧温度.

关键词: 羧甲磺酰基, 蒽醌染料, 中间体, 合成, 脱羧

Abstract: Three anthraquinone dyes containing carboxymethylsulfonyl group and relative in-termediates were synthesized.Thermogravimetry was applied to determine the decarboxyla-tion temperatures of the dyes and intermediates.The results show that decarboxylation tem-peratures decreased when carboxymethylsulfonyl groups connected indirectly with benzenering.

Key words: carboxymethylsulfonyl group, anthraquinone dye, intermediates, synthesis, decarboxylation
