On Kinetics of Esterification from Acrylic Acid and Iso-butyl Alcohol
【摘要】 本文测定丙烯酸和异丁醇在硫酸异丁基酯催化下,生成丙烯酸异丁酯为二级可逆反应,其反应速率方程为:(d[i-BA])/(dt)=k1表观([AA][i-BuoH]-(1/K)[i-BA][H2O])并测得75~95℃温度范围内的表现反应速率常数、平衡常数和活化能.反应方程为:
【Abstract】 In this paper, the kinetics of esterification from acrylic acid and iso-butyl alcohol in the presence of iso-butyl sulphate catalysis is determined. It is found that this reaction is a second-order reversible one, the rate equation is.d[i-BA]/dt=k1表([AA][i-BuOH]-1/K[i-BA][H2O])The observed reaction rate constant, equilibrium constant and activation energy in the temperature range of 75-95℃ are obtaimed, the reaction mechanism expresses as follows:
