Title: Study on synthesis process of 1,3-propanediol from glycerol
Abstract: 1,3-Propanediol is synthesized from glycerol by chloration,cyclization and hydrogenization.The structure of the target compound is determined by IR and 1H-NMR.The optimal reaction conditions are shown as follows:chloration at 90℃ for 3.5 hours with 6%(by mass) acetic acid as catalyst,cyclization at 0℃ for 1.5 hours with 1∶1 of the ratio of 3-chloro-1,2-propanediol and sodium hydroxide(40% by mass),and hydrogenization catalyzed by Co-MgO/silica gel at 100~150℃ for 4 hours with 10∶1 of the ratio of H2 and glycido(20% by mass).The overall yield of the reactions is 58.6%.
