The reaction mechanism of vinyl interchange reaction was investigated using acetic acid labeled with O<SUP>18</SUP> as tracer. In the interchange reaction of vinylacetate and acetic acid using mercuric(II)salts(HgSO4, HgO, 3HgO·SO3)as catalyst, the following experiment was performed to reveal the severed parts in these compounds.<BR> CH<SUB>3</SUB>CO<SUP>18</SUP>O<SUP>18</SUP>H+CH<SUB>3</SUB>COOCH=CH<SUB>2</SUB> ⇔ CH<SUB>3</SUB>CO<SUP>18</SUP>O<SUP>18</SUP>CH=CH<SUB>2</SUB>+CH<SUB>3</SUB>COOH By the obtained determining results of O<SUP>18</SUP>concentration in the reaction equilibrium, the concentration ratio of O<SUP>18</SUP>atomic percentage became 1. Thus it was confirmed by this experiment that the reaction occurred by exchaning the vinyl group of vinylacetate and hydrogen in carboxyl group of acetic acid.
