Abstract
Ethyl 2-butenoate is prepared by 2-butenoate acid,ethanol,sulphuric acid,benzene and tetramethyl ammonium chloride.The reasonable reaction condition is:reaction time 10 hour,ethanol: 2-butenoate acid=2.0∶1.0(mol),sulphuric acid: 2-butenoate acid=0.22∶1.0(mol).In this condition,the yield of ethyl 2-butenoate can reach 84%.The structure of product is characterized by IR,elementary analysis and 1H NMR.
