Description
(54) СПОСОБ ПОЛУЧЕНИЯ ФТОРИСТОГО МАГНИЯ(54) METHOD FOR OBTAINING FLUORINOUS MAGNESIUM
II
Изобретение относитс к получению фтористого магни , примен емого в качестве ректификатора сол ных ванн дл закалки инструмента.The invention relates to the production of magnesium fluoride, used as a rectifier for salt baths for quenching tools.
Известен способ получени фтористого магни включающий взаимодействие гидвокарбоната магни и 15%-но1Ю раствора фторида аммони , нагретого до 90°С. Пульпу перемешивают в течение 1ч, осгшок отдел ют и сушат при . Получают продукт ссодержанием основного вещества 95% Ul.A known method for producing magnesium fluoride involves the interaction of magnesium hydrogen carbonate and a 15% ammonium fluoride solution heated to 90 ° C. The pulp is stirred for 1 hour, the liquor is separated and dried at. Get the product with the content of the basic substance 95% Ul.
Недостатком этого способа вл етс многостадийность процесса.The disadvantage of this method is the multistage process.
Наиболее близким по технической сущности и достигаемому результату к изобретению вл етс способ получени фтористого магни , включающий термообработку смеси карбоната магни и фторид-бифторида аммони при в течение 5-10 мин. Карбонат магни берут с избытком, составл}нощим 5-10% мольных от стехиометрически необходимого, фторид-бифтррид аммони берут по стехиометрии 2.The closest in technical essence and the achieved result to the invention is a method of producing magnesium fluoride, which includes heat treatment of a mixture of magnesium carbonate and ammonium fluoride bifluoride for 5-10 minutes. Magnesium carbonate is taken in excess, amounting to 5–10% molar of the stoichiometrically necessary, ammonium fluoride-bifterride is taken by stoichiometry 2.
Недостатком известного способа вл етс низкое содержание основного вещества в продукте (88%).The disadvantage of this method is the low content of the main substance in the product (88%).
Цель изобретени повышение содержани основного .вещества в продукте до 95-96,5%.The purpose of the invention is to increase the content of the main substance in the product to 95-96.5%.
Поставленна цель достигаетс тем, что согласно способу получени фтористого магнИ , заключающемс в термообработке смеси карбоната магни и фторид-бифторида аммони , фторид-бифторид аммони берут с 5-10%ным избытком от стехиометрически необходимого.The goal is achieved by the fact that according to the method of producing fluoride magnet consisting in heat treatment of a mixture of magnesium carbonate and ammonium fluoride-bifluoride, ammonium fluoride-bifluoride is taken with a 5-10% excess of stoichiometrically necessary.
Кроме того, с целью улучшени ус10 ловий труда за счет предотвращени налипани смеси на стенки аппарата и предотвращени пылени смеси, фторид-бифторид с1ммони берут с содержанием влаги 5-7%.In addition, in order to improve the labor conditions by preventing the mixture from sticking to the walls of the apparatus and preventing the mixture from dusting, the fluorine-bifluoride C1mmonium is taken with a moisture content of 5-7%.
При снижении величины избытка фто15 рид-бифторида аммони ниже 5% происходит снижение содержани основного вещества в продукте, а брать избыток более 10% нецелесообразно, поскольку 20 это не приводит к дальнейшему повышению содержани основного вещества .в продукте.By reducing the amount of ammonium fluoride byfluoride below 5%, the content of the main substance in the product decreases, and taking an excess of more than 10% is impractical, since 20 this does not lead to a further increase in the content of the basic substance.
Пример 1 . Дл получени 1000 г фторида магни смешивают 952 г гидрокарбоната магни с содержанием Example 1 To obtain 1000 g of magnesium fluoride, 952 g of magnesium bicarbonate are mixed with
25 41% Мд и 1163 г смеси бифторида и фторида аммони , полученной из фторсодержащих отходов производства минеральных удобрений, содержащей 5% влаги, до получени однородной массы.25 41% Md and 1163 g of a mixture of bifluoride and ammonium fluoride, obtained from fluorine-containing mineral fertilizer production waste containing 5% moisture, until a homogeneous mass is obtained.
