摘    要:以三氯氧磷、三乙胺、丙烯酸羟丙酯(HPA)等为原料,通过多步法合成了一种磷酸酯反应型乳化剂。实验对原料配比、反应时间、反应温度等进行讨论,得到最佳工艺条件,并用红外光谱对产品进行结构表征。结果表明,合成甲基丙烯酰氧丙基磷酸酯中间体,选择n(三氯氧磷)∶n(三乙胺)∶n(HPA)=1.1∶1.3∶1,反应时间为1.5h,反应温度为25℃,第二步水解反应温度0~15℃,水解物料比为n(中间体产物)∶n(三乙胺)∶n(水)=1∶1.4∶1.2时,最终产物收率最高,可达98.80%。

Abstract:A phosphate ester reactive emulsifier is synthesized via multi steps reaction which uses phosphorus oxychloride, hydroxypropyl acrylate (HPA), and triethylamine as reactants. The optimum technical conditions are acquired by discussing different feed ratios, reaction time and temperature. The product is characterized by IR spectroscopy. The results indicate that the yield of methyl acryloyl oxygen propyl phosphate ester will reach 98.80% when the feed ratio is: n(POC13) : n(triethylamine) : n(HPA) = 1.1 : 1.3 : 1, the reaction time is 1.5h, the reaction temperature is 25℃, and the second step hydrolysis reaction temperature is 0 to 15℃, and the hydrolyzed material ratio is n(intermediate product) : n(triethylamine) : n (water) = 1 : 1.4 : 1.2.
Keywords:Reactive emulsifier  phosphorus oxychloride  methyl acryloyl oxygen propyl phosphate  phosphate ester
