METHOD FOR MANUFACTURING LIGHT-COLORED REFINED TALL OIL ROSIN AND TALL OIL ROSIN ESTER, AND LIGHT-COLORED REFINED TALL OIL ROSIN AND TALL OIL ROSIN ESTER OBTAINED VIA SAID METHOD

摘要

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.
