Abstract

Способ извлечения фторида водорода из его водных растворов, включающий восстановление воды углеродом при повышенной температуре, отличающийся тем, что предварительно испаренную или распыленную смесь фторида водорода и воды приводят в контакт с углеродом, нагретым выше 1000 К, в массовом соотношении вода : углерод от 1:0,5 до 1:2, полученные продукты конденсируют и ректификуют, извлекают безводный фторид водорода, азетропную смесь направляют в рецикл, а несконденсированные газы нейтрализуют и утилизируют.A method of extracting hydrogen fluoride from its aqueous solutions, comprising reducing water with carbon at an elevated temperature, characterized in that the pre-vaporized or atomized mixture of hydrogen fluoride and water is brought into contact with carbon heated above 1000 K in a water: carbon weight ratio of 1: 0.5 to 1: 2, the resulting products are condensed and rectified, anhydrous hydrogen fluoride is recovered, the aetropic mixture is recycled, and non-condensed gases are neutralized and disposed of.
