Abstract
<I>Hydrogen-isotope exchange reaction</I> (T-<I>for</I>-H <I>exchange reaction) between</I> HTO <I>vapor and aliphatic dicarboxylic acid having different number of methylene groups with each other has been observed at 50°C. Consequently, the quantitative relation was obtained between the reaction time and the increase of the activity of aliphatic dicarboxylic acid. The reaction was dynamically analyzed with both the A″-McKay plot method and data obtained.<BR>As to aliphatic dicarboxylic acids, the following two matters have been consequently found : (1) as the reactivity of each material decreases with increasing the number of methylene groups in the material, the effect of the number of methylene groups per molecule on the reactivity of the material can be quantitatively evaluated, (2) using the A″-McKay plot method, the reactivity of solid organic compounds can be evaluated, nondestructively.</I>
