Description
Из авт. св. № 101115 известно получение фтористого кальци путем взаимодействи измельченного карбоната кальци с фтористым аммонием , получаемым взаимодействием газов, содержащих фтористый кремний с оборотным водным раствором аммиака, образовавшимс в качестве побочного продукта при получении .From auth. St. No. 101115, it is known to produce calcium fluoride by reacting pulverized calcium carbonate with ammonium fluoride, which is obtained by reacting gases containing silicon fluoride with a circulating aqueous solution of ammonia, which is formed as a by-product upon receipt.
Насто щее изобретение вл етс усовершенствованием способа получени фтористого кальци по авт. св. № 101115, так как позвол ет увеличить выход целевого продукта и снизить потери аммиака.The present invention is an improvement of the calcium fluoride production method of auth. St. No. 101115, as it allows to increase the yield of the target product and reduce ammonia losses.
Способ заключаетс в том, что реакци взаимодействи раствооа фтористого аммони с карбонатом кальци проводитс при температуре 80-95° (а не 40°, как по авт. св. № 101115) с добавлением к полученной пульпе олеиновой кислоты, с целью ускорени осаждени и фильтрации тонкодисперсного осадка фтористого кальци . Олеинова кислота беретс в количестве 0,15- 0,25% от веса жидкой фазы пульпы.The method consists in the fact that the reaction of ammonium fluoride-fluoride with calcium carbonate is carried out at a temperature of 80-95 ° (and not 40 °, as per auth. St. No. 101115) with the addition of oleic acid to the resulting pulp, to accelerate the precipitation and filtration fine sediment of calcium fluoride. Oleic acid is taken in an amount of 0.15-0.25% by weight of the liquid phase of the pulp.
