摘要：以精制松香、马来酸酐和季戊四醇为原料,制备浅色高软化点马来松香季戊四醇酯。重点讨论了不同还原剂、催化剂、减色剂、原料配比及反应时间等因素对产品性能的影响。研究表明最佳合成条件为:马来酸酐、还原剂SHHP、催化剂R-1、减色剂M-6的用量分别为精制松香质量的13%、0.3‰、3‰、3‰,精制松香和马来酸酐加成反应60min,马来松香和季戊四醇酯化反应150min,所得产品颜色为加纳色号3号,酸值为9.8mg/g,软化点为159℃。
Maleic rosin pentaerythritol ester with light color and high softening point was prepared from refined rosin, maleic anhydride and pentaerythritol. The effects of different reducing agent, catalyst, color-reducing agent, raw material ratio and reaction time on the product performance are emphatically discussed. The optimized condition was obtained through experiments. The proper amount of maleic anhydride, reducing agent SHHP, catalyst R-1 and color-lighting agent M-6 are 13%, 0.3%, 3% and 3% of the refined rosin, respectively. The addition reaction time of maleic anhydride with the refined rosin is 60 min, and then the esterification time with pentaerythritol is 150 min. The product produced under the optimized condition has a Gardner color of 3, an acid value of 9.8 mg/g and a softing point of 159 ℃.
