オレフィンとアクリル酸との反応

抄録

Direct syntheses of alkyl acrylates from acrylic acid and olefins have been studied.
Thus, tert-butyl acrylate was obtained in 73% yield upon treatment of 1 mol acrylic acid with 1.1 mol isobutylene in ethylene dichloride in the presence of 0.05 mol sulfuric acid at 20°C., for 4 hrs under 2 atm pressure.
Similarly, cyclohexyl acrylate was obtained in 80% yield upon treatment of 1 mol acrylic acid with 1.2 mol cyclohexene in ethylene dichloride in the presence of 0.05 mol sulfuric acid at 140°C., for 5 hrs under 40 atm pressure. The apparent activation energy was 18.4 kcal/mol and the reaction was first order in cyclohexene concentration.
