METHOD OF PRODUCING AMMONIUM FLUORIDE

摘要

FIELD: chemistry. ^ SUBSTANCE: invention relates to the technology of inorganic substances and can be used to produce ammonium fluoride. The invention is aimed at reducing the cost of the process of producing ammonium fluoride by reducing the amount and cost of the equipment used. This goal is achieved by that gaseous hydrogen and ammonia are mixed in stoichiometric ratio followed by desublimation of the obtained product. The desublimation process is carried out at atmospheric pressure and below 126C - the melting point of ammonium fluoride. A solid product - ammonium fluoride - is obtained as a result of the described operations. ^ EFFECT: low cost of the end product due to exclusion of the step for trapping hydrogen fluoride in molten ammonium fluoride. ^ 1 ex
