MEASUREMENT METHOD OF “ACIDITY BASED ON KINETIC LOGIC” BY APPLYING HYDROGEN-ISOTOPE EXCHANGE REACTION IN A HETEROGENEOUS SYSTEM

Abstract

Hydrogen-isotope exchange reaction between HTO vapor and one of solid materials (or between Poly(vinyl alcohol)) labeled with tritium and one of liquid materials) was observed. The reaction was analyzed with both the data obtained and the A''McKay plot method, and “the acidity based on kinetic logic” of each material was obtained. It has been found that the A''McKay plot method is useful to obtain “the acidity” of a slightly soluble material.
