Изобретение имеет целью очистку плавиковой кислоты от примеси HgSiFg с помощью бисзльфита или сульфита, причем в процессе очистки не образуетс соединений, которые загр знили бы очищаемую плавиковую кислоту, как это имеет место, например, при очистке с помощью сульфата натри . Сернистый ангидрид , образующийс в результате реакции , полностью улетучиваетс из реакционной массы и может быть ут1{лизирован.The invention aims to purify hydrofluoric acid from the impurity HgSiFg using bis-slyphite or sulphite, and during the purification process no compounds are formed that would contaminate the purified hydrofluoric acid, as is the case, for example, with sodium sulphate. The sulfurous anhydride resulting from the reaction is completely volatilized from the reaction mass and can be used.
Реакции бисульфита и сульфита с HgSiFe проход т по следующим зфавнени м:The reactions of bisulfite and sulfite with HgSiFe are carried out as follows:
HjSiFe + 2NaHS03 + + 2SO, + 2Н,0,HjSiFe + 2NaHS03 + + 2SO, + 2H, 0,

Бисульфит дюжет вводитьс в очищаемую плавиковую кислоту в виде раствора с концентрацией до 500 г/л. Сульфит можно вводить как в растворе , так и в виде кристаллов.Bisulfite duset is introduced into the purified hydrofluoric acid as a solution with a concentration of up to 500 g / l. Sulfite can be introduced both in solution and in the form of crystals.
Предмет изобретени Subject invention
Способ очистки плавиковой кислоты от кремнефтористоводородной кислоты, отличающийс тем, что с целью выделени кремнефтористоводородной кислоты в виде кремнефторида в раствор плавиковой кислоты ввод т бисульфит или сульфит щелочного Л1еталла.A method of purifying hydrofluoric acid from hydrofluoric acid, characterized in that in order to isolate hydrofluoric acid as silicofluoride, bisulfite or sulfite alkaline metal is introduced into the solution of hydrofluoric acid.
