摘要：

依据松香的结构及其氧化机理,考察酚类、亚磷酸酯类、硫酯类等对聚合松香的浅色反应。结果表明:十二硫醇、环氧大豆油、SWC-80可作为聚合松香酯化的浅色剂,以SWC-80为浅色剂、Dy_nO_m为催化剂,制得的浅色聚合松香甘油酯,颜色为2号(加纳),酸值12.1mgKOH·g^-1,软化点为135℃;制得的浅色聚合松香季戊四醇酯,颜色为3号(加纳),酸值22.1mgKOH·g^-1,软化点为143℃。

关键词: 聚合松香, 浅色剂, 酯化反应

Abstract:

According to the structure and oxidation mechanism of rosin, the light-colored reaction of polymeric rosin with phenols, phosphite ester, thioester and etc.was studied. The results indicated that n-Dodecanethiol, epoxy soybean oil, SWC-80 were the preferable color-lightening agents for polymeric rosin. Light-colored polymeric rosin named glyceride with Gardner color 2 was prepared by reacting polymeric rosin with color-lightening agent SWC-80 in the presence of Dy_nO_m catalyst. Its acid value was 12.1 mgKOH·g^-1 and softening point was 135 ℃. At the same condition light-colored polymeric rosin named pentaerythritol ester with Gardner color 3 was prepared. Its acid value was 22.1 mgKOH·g^-1 and softening point was 143 ℃.

Key words: polymeric rosin, color-lightening agent, esterification
