Cuprammonium hydroxide

Description

Copper dissolved in concentrated ammonia resulting in the formation of a copper ammonia complex copper.

Since the earliest (1857) as the Germans found E. Schweizer, also said Schweitzer reagent (Schweizer's reagent). The solvent dark blue solution, the Department of Qingyanghuatong dissolved in concentrated ammonia rather the system, it is generally recognized that following the formation of ammonia complex copper Cu (OH) 2 +4 NH3Cu (NH3) 4 (OH) 2 above ammonia production of copper complexes, the price is two alkali; while pressing for-dissociation ammonia complexes, the price is two alkali; while pressing for dissociation-Cu (NH3) 4 (OH) 2Cu (NH< SUB>3) 42 +2 + OH-. Ammonia copper complexes have excess ammonia in the presence of very stable, but not isolated; When the ammonia concentration is lowered, mainly [Cu (NH3) 4 (OH) k2] exist; the appropriate solution increases the concentration of ammonia, which can be increased solvent dissolved cellulose capacity. The use of cellulose solvent dissolved by the textile fibers, called ammonium copper fiber.
