摘要: 以异丙醇为助溶剂,阳离子交换树脂CT500为催化剂,在消除内外扩散的条件下,在间歇反应釜内对柑青醛直接水合制备新铃兰醛反应动力学进行了研究。考察了搅拌转速、催化剂粒径、反应温度和催化剂质量分数对水合过程的影响。采用LHHW动力学模型对实验数据进行了拟合。采用阿伦尼乌斯公式拟合得到了正、逆反应指前因子分别为0.090 46、5.317 40 mol/(g•s);正、逆反应活化能分别为1.724 7×104、3.391 2×104 J/mol。

Abstract: After internal and external diffusion was eliminated, the kinetics of hydration of Myrac Aldehyde was studied in a batch stirred reactor with isopropyl alcohol as solvent and cation exchange resin as catalyst. The effects of agitation speed, catalyst particle size,temperature of reaction and catalyst concentration on the reaction rate of hydration reaction were studied. The kinetics data of hydration reaction were fitted by LHHW kinetics model. Preexponential factors and reaction activation energy were fitted by Arrhenius equation. The forward and reverse preexponential factors were 0.090 46 mol/(g•s) and 5.317 40 mol/(g•s), respectively. The forward and reverse reaction activation energy were 1.724 7×104 J/mol and 3.391 2×104 J/mol, respectively.
