Abstract
Ethyl acetate was efficiently synthesized by the esterification process, using concentrated sulfuric acid as a catalyst. Systematic studies showed that the molarity ratio of ethanol to acetic acid, dosage of catalyst, reaction temperature, feeding rate of reactants, and washing times played a key role in controlling the productivity and purity of the products. The purity of synthesized ethyl acetate was characterized by the capillary gas chromatograph. It found that with only 5mL of concentrated sulfuric acid the productivity of ethyl acetate reached up to 71.05%. It also revealed that the rate of the addition of the mixture was controlled as 1-3s per drop in order to get high theoretical conversion rates. The optimal temperature of the esterification reaction is 80-85℃. It demonstrated that to reduce the ethanol of the crude product, it is necessary to wash the crude product with saturated calcium chloride at least 2 times to obtain high purity ethyl acetate product. In the paper, the usage of a catalyst of concentrated sulfuric acid was much less than in the other relevant studies.
