Description

In order to reveal the temperature dependence of the reactivity of monosubstituted phenols nondestructively, the hydrogen-isotope exchange reaction (liquid-solid reaction) between one of three species of methoxyphenols dissoluved in p-xylene and poly(vinyl alcohol)labeled with tritium was observed at 50---90 °C. The rate constants for these materials have been obtained with the A"-McKay plots based on the respective data obtained. The followings have been clarified comparing these rate constants (and the rate constants obtained previously) with each other.1) The reactivity of ο-methoxyphenol is about 3x101times that of p-methoxyphenol.2) The temperature dependence of the reaction constant (ρ) for monosubstituted phenol is extremely small.
