摘要: 以衣康酸(IA)、壬基酚聚氧乙烯醚NPEO(10)和亚硫酸钠为基本原料,经过酯化反应和磺化反应,合成了新型乳化剂壬基酚聚氧乙烯醚衣康酸单酯磺酸二钠盐。考察了反应温度和物料物质的量比对反应体系的影响;进而将其应用到苯丙乳液,并与传统乳化剂的用量进行对比。结果表明:反应条件为n(NPEO(10))/n(IA)=1.00∶1.06,n(IA)/n(Na2SO3)=1.00∶1.06,酯化温度为120℃,磺化温度为90℃,反应时间5h下合成的乳化剂,在乳化剂质量分数为2.4%时得到稳定的苯丙乳液用量比传统乳化剂少20%。

Abstract: Disodium nonylphenol polyoxyethylene monoester sulfoitaconate was synthesized through the esterification and sulfonation reactions using nonylphenol polyoxyethylene ester, itaconic acid and sodium sufite as raw materials. The effects of reaction temperature and molar ratios of reactants on reaction were investigated. And the production was applied to styrene-acrylic emulsion polymerization as new emulsifier,which compared with the traditional emulsifier. The results show that the emulsifier was obtained under the condition of n(NPEO (10))∶n(IA)=1.00∶1.06,n(IA)∶n(Na2SO3)=1.00∶1.06, reaction temperature 120 ℃ and 90 ℃. A stable styrene-acrylic emulsion was got with the new emulsifier dosage of 2.4%, the dosage of emulsifier is 20% less when the traditional emulsifier was replaced by new product.
