摘要： 1. The process for cleaving substituted ammonia compounds containing nitrogen-hydrogen bonds selected from the group consisting of alkali metal amides, urea, biuret, sulfamide, formamide, hydrazine, ethylenediamine, cyanoguanidine and melamine and fluorinating the resulting cleavage products, which comprises in combination the steps of:A. introducing into a reaction zone one or more of the afore-mentioned substituted ammonia compounds as starting material and a fluoride catalyst, said fluoride catalyst being a fluoride of a metal which forms an acid salt with hydrogen fluoride,B. subjecting said starting material to the action of elemental fluorine while in the presence of said catalyst,C. maintaining temperatures in the reaction zone substantially in the range of 0.degree.-300.degree.C. but not above the phase change temperature of the starting material if a liquid, or not above the decomposition temperature of the starting material if a solid, andD. collecting from the reaction zone the volatile off-gases containing fluorinated cleavage products.
