Abstract:
A process has been provided for preparing perhalo nitroso alkanes from a halocarbon compound of the formula RCX2H wherein X is fluorine, chlorine, or bromine and R is a halogen or a perhalo radical and wherein the halogens substituents are fluorine, chlorine, or bromine. The process is carried out by reacting the halocarbon with nitrosyl chloride in a vapor phase at a pressure of one atmosphere or less and at a temperature from 160* C. and lower while irradiating the reaction mixture with radiant energy at the characteristic wavelength displayed by nitrosyl chloride.
Abstract:
1. A process for concurrently decreasing the perchloric acid and water content of hydrazinium diperchlorate dihydrate contaminated with perchloric acid and water, comprising the steps of at least once: A. CONTACTING THE HYDRAZINIUM DIPERCHLORATE DIHYDRATE WITH AT LEAST ABOUT AN EQUAL WEIGHT OF CONCENTRATED HYDROGEN FLUORIDE BELOW ABOUT 19* C. until a slurry of solid anhydrous hydrazinium diperchlorate, hydrogen fluoride, perchloric acid and water is formed; and B. SEPARATING THE SOLID ANHYDROUS HYDRAZINIUM DIPERCHLORATE PRESENT IN THE SLURRY.
