Abstract
he kinetics and mechanism of formation of glycerine from allyl alcohol by hydrogen peroxide in the presence of sodium tungstate as catalyst have been studied. The reaction is first order with respect to allyl alcohol and catalyst and zero order with respect to hydrogen peroxide. The mechanism of formation of glycerine is considered to be through epoxidation of allyl alcohol to glycidol and then hydrolysis of glycidol to glycerine. Based on substituent and salt effects the mechanism of formation of glycidol is believed to be concerted with considerable polar (electrophilic) character. The energy of activation has been calculated to be 68.9 kJ mol-1.
