acetone

In this paper the possibility of obtaining almost non-chloride products with the help of the experimental studies of selective extraction of sodium and potassium chlorides from intermediate product of processing solutions tailings potash industries - sediment of potassium-magnesium salts with a high chloride content (over 25 %) using aqueous organic extractant (acetone, methanol, ethanol) was proved. It is shown that to achieve a high yield of product the extraction process should be carried out in 40% aqueous acetone.

The results of comparative studies of the chloride extraction from a mixture of sulfate salts of chloride by aqueous and organic extractants based on ethanol, isopropanol and acetone are given. It was found that the most effective reagent for obtaining chlorine free product is ethanol. 
Наведені  результати  порівняльних  досліджень  екстрагування  хлоридів  із  суміші сульфатно-хлоридних  солей  водно-органічними  екстрагентами  на  основі  етанолу, ізопропанолу  та  ацетону.  З'ясовано,  що  найефективнішим  реагентом  для  одержання безхлоридного продукту є етанол.
