摘要/Abstract

摘要： 常压下、温度20～50℃,测定了鼓泡反应器中羰基硫(COS)在1.3130～4.4038mol/LNaOH水溶液中的水解速率,获得一级快速不可逆反应的水解速率表达式,其表观活化能为59.63kJ/mol.

Abstract: Hydrolysis rate of carbonyl sulphide was determined in a bubble reactor at 20-50℃, sodium hydroxide concentration 1. 3130-4. 4038 mol/L and atmospheric pressure. The first-order rate expression for the hydrolysis of carbonyl sulphide is Ink1 =27.90 - 7168/T + 0.56I where, Ncos,Hcos,pcos,i are absorption rate, solubility coefficient and partial pressure at interface of COS respectively. The constant ki is first-order rate-constant of forward reaction and I is ionic strength for initial concentration of NaOH. The apparent activation energy is 59.63 kJ/mol.
