| Abstract: | By using gallium sulfate supported on solica gel as the catalyst, lactic acid and n-butanol reacted to form butyl lactate. Some effects were investigated such as amount of catalyst, reaction time,molar ratio of alcohol to acid, different carrying water agents and repeated uses. Experimental results showed that it was the efficient and economic catalyst.Under the best conditions its yield could reach 88.9%. |
