Изобретение относитс  к технологии получени  фтористых соединений щелочноземельных элементов и может быть использовано в промышленности, производ щей оптические материалы и химические реактивы.The invention relates to the technology for producing fluorine compounds of alkaline-earth elements and can be used in the industry producing optical materials and chemical reagents.

Известен способ оолучени  фтористого магни  осаждением из водного раствора его соли -плавиковой кислотой. Недостатками такого способа  вл ютс  сравнительно низкий выход (90%) целевого продукта с содержанием основного вещества 97% и длительность процесса осаждени  фтористого магни .There is a known method for the production of magnesium fluoride by precipitating its hydrofluoric acid from an aqueous solution of its salt. The disadvantages of this method are the relatively low yield (90%) of the target product with a basic substance content of 97% and the duration of the magnesium fluoride precipitation process.

С целью устранени  указанных недостатков предложено осаждение вести в присутствии гидрофоофата аммони .In order to eliminate these drawbacks, precipitation is proposed to lead in the presence of ammonium hydrophoofate.

Это позвол ет получать продукт с содержанием фтористого магни  выше 99%.This makes it possible to obtain a product with a magnesium fluoride content greater than 99%.

Гидрофосфат аммопи  целесообразно брать в количестве 1,1-2,4 моль на 1-2 моль соли магни .Ammopi hydrogen phosphate is advisable to take in the amount of 1.1-2.4 mol per 1-2 mol of magnesium salt.

Выход втористого магни  100%.The output of secondary magnesium is 100%.

Пример. В реактор с мешалкой наливают 10 л раствора хлористого магни  (концентраци  г/л), затем добавл ют 10 л 14%ного раствора гидрофосфата аммони  и при нопрерывном перемешивании приливают 2 л 40%-пой плавиковой кислоты. Полученный осадок фтористого магпи  отдел ют от маточного раствора декантацией, промывают деминерализованной водой, сушат и прокаливают при 1050°С в тсченпе 1 час. Выход продукта . Содержание основпого вещества 99,5-99,9%. Сумма примесей т желых металлов 2-10-2%;Example. 10 l of a solution of magnesium chloride (concentration g / l) is poured into the reactor with a mixer, then 10 l of a 14% solution of ammonium hydrogen phosphate are added and 2 l of 40% hydrofluoric acid are poured with continuous stirring. The resulting precipitate of fluorine muppee is separated from the mother liquor by decantation, washed with demineralized water, dried and calcined at 1050 ° C in 1 h. The yield of the product. The content of the basic substance is 99.5-99.9%. The amount of heavy metal impurities is 2-10-2%;
