Studies on the Synthesis of Sodium-5-sulfoisophthalic Acid Dimethyl Ester

改善涤纶纤维的染色性能和色泽鲜艳度的一条重要途径是将涤纶进行改性。本文讨论了以发烟硫酸为磺化剂制备涤纶纤维阳离子染料可染改性剂─ 5 磺酸钠间苯二甲酸二甲酯(SIPM )的工艺条件 ,并提出了适合工业生产的工艺流程和最佳技术参数。

The modification is a important way for improved the dyeabitily of polyester fibre .In this paper the productive conditions of the modifier, Sodium 5 Sulfoisophthalic acid dimethyl ester(SIPM),were studied by use of furring sulfuric acid as a sulfonating agent and the process flow and the technology parameters used for industrial production were also provided.
