| 摘 要： | 利用一水硫酸氢钠为催化剂使丙烯酸和异丁醇酯化合成了丙烯酸异丁酯;研究了一水硫酸氢钠用量、异丁醇用量、反应时间、温度及阻聚剂用量对丙烯酸异丁酯收率的影响.结果表明,当异丁醇与丙烯酸物质的量之比为3∶1,硫酸氢钠催化剂用量为丙烯酸量的2%,阻聚剂(对苯二酚)用量为丙烯酸质量的0.05%,反应时间为3h,反应温度为115℃时,酯化产率可达88.51%.

| Abstract: | Iso-butyl acrylate was synthesized in high yield through the esterification of acrylic acid and iso-butanol under the catalysis of sodium bisulfate monohydrate .The effects of sodium bisulfate monohydrate dosage ,iso-butyl alcohol dosage ,reaction time ,temperature and poly-merization inhibitor dosage on the yield of iso-butyl acrylate were investigated .It was found that ,w hen the molar ratio of iso-butyl alcohol to acrylic acid is fixed at 3∶1 ,the molar ratio of sodium bisulfate monohydrate to acrylic acid is fixed at 2% ,the mass ratio of polymerization inhibitor （hydroquinone） to acrylic acid is fixed at 0 .05% ,the yield of the ester could reach 88 5.1% under a reaction temperature of 115 ℃ and a reflux reaction time of 3 h . |
