Abstract

A new type of the isotope exchange method of analysis is proposed. The method can be applied to the exchange system in which the rate of the exchange reaction is rather slow but measurable, before the exchange equilibrium is attained. The validity of the principle of the method is verified experimentally with several exchange systems of RyI+KI*⇌RyI*+KI (RyI stands for alkyl, alkylene or benzyl iodide) type. The iodine content of the organic iodine compounds can be determined with an error of ±4%.
