A method of heterogeneous exchange of alkylhalides with halogens in solid-gas systems is reported where the exchange takes place between iodine, absorbed on rhodium, and alkyliodides. The labelling yields are tabulated. The chemical purity of the labelled product was checked by radio gas chromatography from which it was deduced that s simple exchange reaction took place with the ethyl iodide, and thst the free iodine content was not increased by the labelling procedure. This means that when using sn organic iodide of high purity (i.e., free of elementary iodine) no purification of the labelled product is necessary. (UK)
