Description
Изобретение относитс к области очистки красного фосфора, который может найти применение при получении продукта дл геттера.This invention relates to the field of purification of red phosphorus, which can be used in the preparation of a getter product.
Известен способ очистки красного фосфора путем смачивани его водой, промывки раствором пделочи, затем дистиллированной водой , слабой сол ной кислотой и снова водой. Затем фосфор размалывают во влажном состо нии в шаровой мельнице в течение 300 час, промывают дистиллированной водой и этиловым спиртом и сушат на воздухе. Однако смачивание фосфора водой вл етс длительной и трудоемкой операцией, так как происходит в течение 1-2 мес цев при периодическом перемешивании.A known method of purification of red phosphorus by wetting it with water, washing it with a solution of delicacy, then distilled water, weak hydrochloric acid and again with water. Then the phosphorus is milled in a wet state in a ball mill for 300 hours, washed with distilled water and ethyl alcohol, and air dried. However, wetting of phosphorus with water is a long and laborious operation, as it occurs within 1-2 months with occasional stirring.
Дл интенсификации процесса смачивани предлагаетс перед смачиванием обрабатывать фосфор ацетоном.In order to intensify the wetting process, it is proposed to process phosphorus with acetone before wetting.
Смесь перемешивают, отстаивают и декантируют фосфор. Далее его обрабатывают по известной технологии. Смачивание фосфора водой сокраш,аетс до 1 суток.The mixture is stirred, settled and decanted phosphorus. Next, it is processed by known technology. Wetting phosphorus with water, coscash, lasts up to 1 day.
Предмет изобретени Subject invention
Способ очистки красного фосфора путем смачивани фосфора водой, обработки щелочью и кислотой с промывкой фосфора после каждой операции дистиллированной водой, отличающийс тем, что, с целью интенсификации процесса, перед смачиванием фосфор обрабатывают ацетоном.The method of purification of red phosphorus by wetting phosphorus with water, treating with alkali and acid and washing phosphorus after each operation with distilled water, characterized in that, in order to intensify the process, phosphorus is treated with acetone before wetting.
