| Abstract: | The preparation of chitosan sulfate and its main influential factors have been studied including its catalytic reaction and stability in some esterfations, and ethyl-hdroxybenzoate has been catalytically synthesized with chitosan sulfate. The reaction condition of-phydroxybenzoic acid with nbutyl alcohol by using chitosan sulfate as catalyst has been dealt with, and influences of amount of catalyst, the molar ration of alcohol toacid and reaction time that effects the esterifation have been mainly discussed. |
