The rate coefficient of reaction between liquid C18 alpha-olefin and gaseous SO3 dissolved in it is measured by using a pulse method, developed first to measure the film coefficient of mass-transfer in packed beds. To interpret the rate data obtained from the pulse reactor, a criterion is developed based on the penetration theory to approximate the behavior of a rapid second-order irreversible reaction by that of a pseudo first-order reaction. Experimental procedures and the underlying concept of getting rate coefficient by the pulse method are given to apply it to gaseous SO3 absorption by liquid alpha-olefins. The second-order rate coefficient k2 of the reaction for liquid C18 alpha-olefin and SO3 dissolved in it is found to be:
k2 = 7.7×109exp(-6.2×103/RT)
