Preparation of Fe3O4@SiO2–ZnO catalyst and its catalytic synthesis of rosin glycol ester

In our paper, the optimal process conditions for rosin glyceride were obtained as follows: zinc acetate is the zinc source, the theoretical load of zinc source is 0.25 g, the reaction temperature is 240°C, the reaction time is 5 h, and the amount of catalyst is 0.2 g. The esterification rate was 81....
