Abstract
Способ получения безводного фтороводорода и плавиковой кислоты ректификацией фтороводородной кислоты, содержащей свыше 65 мас.% фтороводорода с получением в дистилляте фтороводорода и плавиковой кислоты в кубовом остатке колонны, отличающийся тем, что процесс проводят при температуре паров в кубовой части колонны 115-130°С в интервале значений флегмового числа, равного 2-5, при этом содержание основного вещества во фтороводороде не менее 99,95% и плавиковой кислоты 40-45%. The method of producing anhydrous hydrogen fluoride and hydrofluoric acid by rectification of hydrofluoric acid containing more than 65 wt.% Hydrogen fluoride to obtain hydrogen fluoride and hydrofluoric acid in the distillate of the column bottoms, characterized in that the process is carried out at a vapor temperature in the bottoms of the column of 115-130 ° C in the range of reflux numbers equal to 2-5, while the content of the main substance in hydrogen fluoride is not less than 99.95% and hydrofluoric acid 40-45%.
