Последовательность операций и их режимы те же, что и в прим ре 1 за тем исключением, что вместо серной кислоты берут фосфорную кислоту. Продукт по содержанию примесей аналогичен полученному в примере 1. Формула изобретени  1. Способ очистки хлористого аммони  от примесей катионов металлов путем его сублимации с последующей конденсацией сублимата , отличающийс  тем, что, с делью повышени  степени очистки продукта,хлори тый аммоний перед сублимацией обрабатывают при 90-110 С 1-2%-ным раствором серной или фосфорной КИСЛОТ} вз тых в количестве 5-10% от веса исходного хлористого аммони , сублимацию ведут сначала при 260-270°С до перехода в парообразную фазу 25-35% продукта, а затем при 290300°С , и конденсацию сублимата ведут при 15-25 С. (54) METHOD FOR CLEANING CHLORINE AMMONIUS Sa - IlOVo, Fe 5-ld%, Mn, Si 1-lOi 3-10%, Pb, C, Nl, Co - 1 P p and m 2. Sequence of operations and their modes the same as in example 1, except that phosphoric acid is taken instead of sulfuric acid. The product content of impurities is similar to that obtained in Example 1. Claim 1. The method of purification of ammonium chloride from impurities of metal cations by its sublimation followed by condensation of the sublimate, characterized in that, in order to increase the degree of purification of the product, ammonium chlorite is treated at 90 before sublimation. -110 With a 1-2% solution of sulfuric or phosphoric ACIDS} taken in an amount of 5-10% by weight of the initial ammonium chloride, sublimation is first carried out at 260-270 ° C before the transition to the vapor phase 25-35% of the product, and then at 290300 ° C, and the sublimate condensation is carried out at 15-25 C. 2.
