摘要: 首先从松香树脂中分离提纯出左旋海松酸,经光敏氧化、过氧化反应制得左旋海松酸环过氧化物。在微波条件下,以杂多酸季胺盐为催化剂,将左旋海松酸环过氧化物、硬脂酸、季戊四醇一定比例一步反应合成松香酸硬脂酸季戊四醇复合酯。结果表明,该复合酯作为聚氯乙烯(PVC)热稳定剂,对PVC制品的静态热稳定性、动态热稳定性、刚果红时间、吸水性、电性能等都有较好的改善效果。

Abstract: Levopimaric acid transannular peroxide was prepared from levopimaric acid, which was purificationed from abietic resin, through direct photo-oxidation and peroxidation reaction. Then the composite ester was prepared from a mixture of stearic acid, levopimaric acid transannular peroxide, and pentaerythritol, using heteropolyacid quaternary ammonium as a catalyst with microwave heating. It showed that the composite ester constituted an excellent stabilizer for PVC. The effects included improving static heat stability, damanic heat stability, Congo-red time, water absorption, electric property, and so on.
