【摘要】 采用传统松香酯生产设备及工艺，用ＷＸＦ浅色剂生产松香甘油酯及季戌四醇酯，其加纳色号分别可达５～６级和４～７级。产品热稳定性和抗氧化性能明显优于传统松香酯，可大幅度提高以松香酯为原料的化学品质量，而生产成本并不增加。更多还原

【Abstract】 The rosin glycrol ester and rosin pentaerythritol ester are made by adding Light-clolured agent. The Colour grade of the esters is 5-6 and 4-7 grade (Gardner 1963) respectively.The heat resistonce and oxidation stability of the products are superior to the original rosin esters. The products can significantly improve the quality of the chemicals which is correlative to the esters.更多还原
