METHOD TO MANUFACTURE SALTS OF DODECAHYDRO-CLOSO-DODECABORIC ACID Russian patent published in 2008 - IPC C01B35/18

Abstract RU 2323879 C2

FIELD: chemistry.

SUBSTANCE: at first, aqueous solution, which contains anions of dodecahydro-closo-dodecaboric acid, is reacted with chitosanium ions containing solution. Resulting precipitate of chitosanium dodecahydro-closo-dodecaborate is isolated and decomposed by adding ammonia hydroxide or hydroxide of one of the following metals: Li, Na, K, Ca, Ba, Sr, Ra. This results in formation of chitosan precipitate and solution, which contains the corresponding metal or ammonium dodecahydro-closo-dodecaborate.

EFFECT: decrease in the process energy consumption and duration and improvement of environmental safety thereof.
