Abastract In this paper, the conditions for preparation of light-color rosin glycerin ester were studied. The effect of catalyst，antioxidant and color reducing agent on the product was investigated. The optimum condition was that the amount of nanometer catalyst, antioxidant and color reducing agent was 0.2%, 0.3%~0.4%and 0.6%~0.8%respectively, all of which were based on the weight of rosin.
