The order of the exchange reaction between potassium ethyl xanthate and elemental sulphur was determined. A mixture of ethanol and toluene was used as the solvent for the routine preparation of 35 S‐labelled ethyl, n ‐ butyl , n‐hexyl and n ‐octyl xanthates at a temperature of 20°C. The dependence of the exchange rate on the presence of water was observed. The decomposition of 35 S‐labelled ethyl xanthate in dilute hydrochloric acid was used for the preparation of labelled carbon disulphide.
