摘　　要：综述了近20年来涤纶染色改性剂间苯二甲酸二甲酯-5-磺酸钠(SIPM)合成研究进展。将其制备方法分析归纳为磺酸结晶法、磺酸中和法、酯化磺化法、氯磺酸磺化法、"一锅煮法"5种,并对普通采用的"一锅煮"法的制备工艺及其工艺控制和产品质量分析方法进行了介绍,认为以间苯二甲酸(IPA)为原料,30％发烟硫酸为磺化剂,经磺化、酯化、中和和重结晶工艺是制备SIPM较佳的技术路线。The research progress in synthesis of sodium dimethyl isophthalate-5-sulfonate (SIPM) , a dye modifier for PET fibers, was reviewed in recent 20 years. The synthesis technology was concluded as 5 routes, including sulphonic acid crystallization, sulphonic acid neutralization, esterification and sulfonation, chlorosulfonic acid sulfonation and 'boiling together' method. The process control and product analysis of the common 'boiling together' method were introduced. The satisfied synthesis technology comprised sulfonation, esterification, neutralization and recrystallization with isophthalic acid (IPA) as raw material and 30% oleum as a sulfonating agent.
