HF byproducts: O2; Condensing of starting materials (molar ratio KrF2:CeO2 = 3:1 or 2:1) with anhyd. HF and keeping at room temp. for 24 h. React. is followed from change in colour of suspn. and total pressure of liberated gases.; Sepn. of resulting fluoride from HF by decantation, detn. of F and Ce after keeping (30°C, 1 h) in vac. X-ray diffraction, elem. anal., thermal anal. Well crystd. CeF4 is obtained by keeping the product underreact. conditions, for about 4 d.;
