| Abstract: | The esterification of hydrogenated rosin and glycerin with ZnO catalyst was studied. Four factors and four levels which influence the esterification rate were investigated by orthogonal experiment, and optimum technological conditions have been attained as follows: ratio of acid to alcoho ( 2.0 :1), reaction temperature ( 2701), reaction time (3h), the amounts of catalyst (0. 2 %). The hydrogenated rosin glycerin ester prepared by authors according to national standard (GB10287 - 88) ,and the reaction temperature was considered as the main factor that influence the esterification rate by range analysis. |
