摘要: A highly active and stable SO42–/γ-Al2O3 catalyst was developed, the catalytic activity evaluated for esterification of glycerol. The reactions were performed in a batch reactor under reflux conditions. influence reaction conditions, such as temperature, amount, acetic acid/glycerol mole ratio, on product distribution investigated. results demonstrated that 2 M very showed 100% glycerol conversion with 77.4% selectivity higher esters [glycerol diacetate (DAG) + triacetate (TAG)] at 95 °C, after 5 h time presence ratio 12:1. Further, response surface methodology (RSM) used development empirical process model, followed by optimization parameters. depicted 76.1% combined to DAG TAG can be achieved complete 108.8 °C 0.36 g c...
