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 35S-labelled ethyl, n-butyl, n-hexyl and n-octyl xanthates at a temperature of 200 C. The dependence of th

## Abstract The preparation and stability of ^32^P and ^51^Cr labelled sodium polyphosphates have been studied. The influence of the chromium concentration on the solubility of the chromiumβsodium polyphosphate indicates that its effects are more critical in the preparation of the crossβlinked vari
