Abstract

Способ очистки фтористого водорода от фторидов кремния и фосфора путем пропускания газовой смеси через фторид натрия, отличающийся тем, что смесь контактируют с фторидом натрия при температуре 20-40°С и давлении 100-200 мм рт.ст. до образования полигидрофторидов натрия и комплексных фторидов примесных элементов, после чего повышают температуру до 55-70°С и проводят десорбцию фтористого водорода.The method of purification of hydrogen fluoride from silicon fluorides and phosphorus by passing a gas mixture through sodium fluoride, characterized in that the mixture is contacted with sodium fluoride at a temperature of 20-40 ° C and a pressure of 100-200 mm RT.article until sodium polyhydrofluorides and complex fluorides of impurity elements are formed, after which the temperature is raised to 55-70 ° C and hydrogen fluoride is desorbed.
