摘要
提供了以６０％ 发烟硫酸为磺化剂制备５－磺酸钠间苯二甲酸二甲酯（ＳＩＰＭ ）的工艺技术。后处理采用二次重结晶的工艺，产品质量好，产品损失少。
Sulfonation of isophthalic acid with 60% oleum in the process for synthesising sodium 5 sulfoisophthalic acid dimthyl ester (SIPM) & c. were discussed. The crude sodium 5 sulfoisophthalic acid dimthyl ester was purified by double recrystallization. The product quality criterion was met and the product loss was low.
