十二烯基琥珀酸酐

十二烯基琥珀酸酐用途

该品主要用作环氧树脂固化剂，用于浇铸和层压制品，一般用量120-150℃。制品具有良好的冲击韧性和电性能，但耐热性略差。该品还用于纸张上胶剂、防锈剂、醇酸树脂柔软性改良剂、塑料增塑剂、油墨配合剂、皮革憎水处理剂、干燥剂，聚氯乙烯稳定剂的生产。十二烯基丁二酸酐进行水解，减压脱水即得十二烯基丁二酸（C16H28O4）。这是一种油品防添加剂，在透平油、液压油、主轴油、导轨油、切削油中加入该品均起防锈作用，效果良好

十二烯基琥珀酸酐制备

根据原料烯烃分子链结构不同，十二烯基丁本酸酐可分为直链十二烯基丁二酸酐和支链十二烯基丁二酸酐等两个品种。支链十二烯基丁二酸酐由顺丁烯二酸酐与叠合汽油在加热的条件理进行反应，得到的十二烯基丁二酸酐粗品经水洗后进行减压蒸馏，收集165-240℃（0.53-1.33kPa）馏分即为十二烯基丁二酸酐成品。直链十二烯基丁二酸酐则是采用长链正构烷烃脱氢后，经烷烯分离制得的高纯度直链内烯烃（C11-C12烯93%，C11-C12烃7%）为原料，与顺丁烯二酸酐在加热条件下反应，得到直链十二烯基丁二酸成品。
