Известен способ очистки технической плавиковой кислоты ректификацией при добавлении в куб колонны перманганата « маннита . Однако этот способ не дает возможности получить плавиковую кислоту с содержанием мышь ка ниже 5-10 -1-10 %.A known method of purification of technical hydrofluoric acid by distillation when manganite “permanganate“ is added to the cube. However, this method does not allow obtaining hydrofluoric acid with a mouse content below 5-10 -1-10%.
В предлагаемом способе дл повышени степени чистоты ректификацию провод т при добавлении в куб колонны только перманганата . Кроме того, перманганат подают на нижние тарелки колонны с концентрацией 0,2-0,4%. Раствор маннита подают на верхние тарелки колонны с концентрацией 0,04-0,1%.In the proposed method, in order to increase the degree of purity, rectification is carried out by adding only permanganate to the cube of the column. In addition, the permanganate is served on the lower plates of the column with a concentration of 0.2-0.4%. A solution of mannitol is served on the top plates of the column with a concentration of 0.04-0.1%.
Пример. Загрузив в куб терфлоновой ректификационной колонны 1 кг технической плавиковой кислоты, содержащей 3% перманганата кали (0,8 г КМпО4 на 1 кг), вагревают кислоту до температуры кипени , после чего начинают непрерывно подавать в куб техническую плавиковую кислоту (300 г/час), содержащую перманганат (3%). Температуру в кубе поддерживают в интервале 112- 115°С, температуру иа тарелках колонны 110-П2°С.Example. By loading 1 kg of technical hydrofluoric acid containing 3% potassium permanganate (0.8 g KMnO4 per 1 kg) into a cube of a terflon distillation column, the acid is heated to the boiling point, after which they begin to continuously feed into a cube of technical hydrofluoric acid (300 g / h) containing permanganate (3%). The temperature in the cube is maintained in the range of 112-115 ° C, and the temperature of the plates of the column is 110-P2 ° C.
На вторую тарелку колониы подают 0,2%-ный раствор перманганата кали - примерно 0,1 г на 1 кг исходной смеси. На четвертую тарелку колонны также подаютOn the second plate of the colony serves a 0.2% solution of potassium permanganate - about 0.1 g per 1 kg of the initial mixture. On the fourth plate the pillars also serve
раствор маннита с концентрацией 0,04% в количестве 0,02 г на 1 /сг исходной кислоты. Флегмовое число около 3.a solution of mannitol with a concentration of 0.04% in the amount of 0.02 g per 1 / sg of the starting acid. Reflux number about 3.
Полученна кислота содержала мышь ка ЫО- фосфора 2-10-, бора 2-10- других металлов в среднем 1 .The resulting acid contained mouse AOO-phosphorus 2-10-, boron 2-10- other metals on average 1.
