The present invention provides a method for manufacturing light-colored purified tall oil rosin comprising a distillation process of distilling unpurified tall oil rosin in a presence of activated carbon. The present invention further provides a method for manufacturing a tall oil rosin ester comprising a rosin production process of producing light-colored purified tall oil rosin by this method for manufacturing, an esterification process of carrying out an esterification reaction of the purified tall oil rosin obtained in the rosin production process and alcohols, and an antioxidant-addition-process of adding at least one antioxidant selected from the group consisting of a sulfur-based organic compound, a thiophosphite-based organic compound and a phosphorus-based antioxidant during or after the esterification process.
本发明提供了一种制造浅色纯化妥尔油松香的方法,包括在活性炭存在下蒸馏未纯化妥尔油松香的蒸馏过程。本发明进一步提供了一种妥尔油松香酯的制造方法,包括通过该制造方法生产浅色纯化妥尔油松香的松香生产工艺、将松香生产工艺中获得的纯化妥尔油松香与醇进行酯化反应的酯化工艺、抗氧化剂添加工艺:在酯化过程中或酯化后添加至少一种抗氧化剂,该抗氧化剂选自硫基有机化合物、亚硫磷酸酯基有机化合物和磷基抗氧化剂组成的组。
