Abstract

PURPOSE: To obtain a rosin ester with a light color and a low acid value, by esterifying a rosin with a polyhydric alcohol in the presence of a lithium compound as a catalyst and an org. sulfur compound as a color-lightening agent.
CONSTITUTION: 100pts.wt. of a rosin, 0.01W5pts.wt. of a lithium compound and 0.01W3pts.wt. of an org. sulfur compound shown by the formula (wherein A is a benzene ring or a naphthalene ring type substituted aromatic ring residue; R is H, 1W20C alkyl, cycloalkyl; n is 1W2; m is 1W5; x is 1W2; y is 0W2; p is 0W5) are added to an appropriate amount of a polyhydric alcohol and mixed and reacted. As a lithium compound to be used, lithium hydroxide or lithium carbonate are designated. As a polyhydric alcohol, pentaerthritol, glycerine or diethylene glycol are designated.
