【摘要】 在一水硫酸氢钠存在下由乙醇与乙酸酯化合成乙酸乙酯。研究了乙醇、乙酸与硫酸氢钠摩尔比、反应时间对其收率的影响。当乙酸、乙醇和硫酸氢钠的物质的量之比为 1∶1 6 5 :0 .0 73,回流 1h ,酯收率达到 5 7 4 %。更多还原

【Abstract】 Ethyl Acetate was synthesized by esterification of ethyl alco hol with acetic acid in the presence of the sodium bisulfate monohydrate.The effects of ethyl alcohol,acetic acid and sodium bisulfate molar ratio,the re action time on the yield of ethyl acetate has been inverstigated.The yield of the ester could reach 57.4% under amount of substance ratio of acet ic acid,ethly alcohol and sodium bisulfate were 1∶1 65∶0.073,refluxing for 1 0 hour.更多还原
