摘要

Seven different types of lac of Rajshahi region were oxidized with periodic acid,In order to find out the optimum condition of oxidation,a series of experiments was carried out and the effect of time concen-traion,volume of solvent and the quantity of lac were taken into consideration.Percentage of dihydroxy compound and periodic acid from aleuritic acid,hydrolysed shellac,katiki seed lac,dewaxed shellac,baisaki seed lac,shellac(commercial)and old shellac are (102.50,368,20),(34.25,128.79),(15,10,53.55),(13.95,50.60),(12.90,50.29),(12.69,48.95)respectively.
