| Abstract: | Using solid acid as a catalyst,the following esters were prepared by means of direct esterfication:Glycol monoacetate,Glycerol monoacetate,Glycol monopropionate, Glycerol monopropionate,Glycol monobutyrate,Glycerol monobutyrate,Ethyl phenylacetate,n-Propyl phenylacetate,Isoamyl phenylacetate and.phenylethyl phenylacetate.And some physical constants(bp.n_D~(20))of these esters were determined.Ex- perimental parameters(catalyst,azeotropic agent,reaction temperature,ete.)were exam- incd,Some interesting results are obtained. |
