硫代二丙酸双十二烷酯制备

1. 丙烯腈路线
丙烯腈与硫化钠水溶液在20'E：±2℃下缩合，反应产物经水洗、分离，再用55%的硫酸水解得到硫代二丙酸；将析出并分离得到的硫代二丙酸溶于水中，在硫酸作用下，与月桂醇减压酯化，反应产物经丙酮溶解、碳酸钠中和、压滤、结晶、过滤、干燥得成品。
每吨产品消耗丙烯腈700kg，57%的硫化钠900kg，浓硫酸700kg，月桂醇1100kg。
2CH2＝CHCN+Na2S→S(CH＝CHCOONa)2[H2SO4] →S(CH＝CHCOOH)2
S(CH＝CHCOOH)2+2C12H25OH→S(CH＝CHCOOC12H25)2+2H2O

硫代二丙腈的制备　将丙烯腈加入搅拌反应器中，搅拌下缓缓加入硫化钠水溶液，在（20±2）℃下进行缩合反应，反应产物经水洗、分离，得硫代二丙腈：

2. 丙烯酸路线
在50℃含NaOH的Na2S水溶液中滴加定量的丙烯酸，控制滴加速度使温度低于75℃，滴加完毕后，加热至沸，回流1.5h。待溶液稍冷后，加人50%的硫酸至Ph=1，冷却后析出硫代二丙酸，过滤得粗品，熔点为26℃。
在上述产品中加入定量的月桂醇，在真空下缓缓加热至硫代二丙酸全部溶解，反应终点温度为110℃，真空度大于0.097MPa，然后向混合物中加入水，使产物析出；先后用碳酸钠溶液和水洗至中性，经真空干燥得成品，熔点39～40℃。
2CH2＝CHCOOH+Na2S→S(CH＝CHCOONa)2[H2SO4] →S(CH＝CHCOOH)2
S(CH＝CHCOOH)2+2C12H25OH→S(CH＝CHCOOC12H25)2+2H2O

硫代二丙酸的制备　将硫代二丙腈加入搪玻璃反应釜，搅拌下加入55%的硫酸溶液进行水解，反应产物经过滤得硫代二丙酸：

抗氧剂TPL的制备　将硫代二丙酸和水加入搪玻璃反应釜，搅拌溶解后，加入月桂醇和浓硫酸，搅拌下进行酯化反应，得粗品抗氧剂DLTP。酯化反应在负压下操作，脱除反应生成的水。反应产物经丙酮溶解、碳酸钠中和、压滤、结晶、过滤、干燥而得成品。反应式如下：
