摘　　要：羧乙基硫代丁二酸(CETSA)是近年来研发的新型酸性分散剂。这类物质中每单个分子含有三个羧基和一个磺酸基,具有极强的酸性(相当于等量的质量分数为50%的冰醋酸)。羧乙基硫代丁二酸亦具有较强的分散能力和防止二次沉积的能力,因此,在酸性条件下具有广泛的应用。主要探讨了羧乙基硫代丁二酸的合成,以及在纺织印染免中和酸性皂洗工艺中的应用。Carboxyethylthiosuccinic acid was the novel acidic dispersing agent in recent year＇s. Carboxyethylthiosuccin-ic acid＇s molecule contained three carboxyl groups and one sulfonic acid group, so CETSA was a kind of strong acid, which acid was equivalent to the equivalent of 50% acetic acid. Carboxyethylthiosuccinic acid also had strong dispersion ability and prevent-deposition ability, therefore CETSA had wide application un-der acidic conditions. The Carboxyethyhhiosuccinic acid＇ s synthesis and it＇ s application as escaping neu-tralization of acidic soaping process in the textile printing and dyeing industry were mainly discussed.
