【摘要】 报道了对马来酸二异辛酯的磺化反应进行改进的研究。采用非外加的、少量的马来酸单异辛酯钠盐作为相转移催化剂，在常压下进行磺化反应得到标题产物。磺化反应最佳工艺条件：ｎ（ＮａＨＳＯ３）∶ｎ酯＝１．０７∶１．００（ｍｏｌ∶ｍｏｌ）；ｍ水∶ｍ酯＝０．８１∶１．００（ｇ∶ｇ）；加热介质温度为１３５～１４０℃。对磺化废水的循环套用也进行了研究。更多还原

【Abstract】 A new sulfonation process of di（2ethylhexyl）maleate was reported. By using a small amount of sodium salt of maleic acid monoester as phasetransfer catalyst,the title product was obtained by sulfonation under normal pressure. The optimum condition of sulfonation was:n（NaHSO₃）∶n（ester）=1.07∶1.00（mol∶mol）,m（H₂O）∶m（ester）=0.81∶1.00（g∶g）;the temperature of heating medium,135～140℃. Waste water from the sulfonation was reused.更多还原
