Beschreibung

Allgemeine Beschreibung

NH₄Cl is highly corrosive, colorless salt which dissolves readily in water. It crystallizes out of aqueous solution in octahedrons, in a feathery array, forming a fibrous mass of crystals. It sublimes at 340^oC. Ammonium chloride acts as catalyst in one-pot,Biginelli condensation reactions of aldehydes, 1,3-dicarbonyl compounds and urea or thiourea. Inorganic ammonium ions, NH₄⁺, have been reported as efficient catalysts for the aldol condensation of carbonyl compounds.NH₄Cl has been reportedly used to enhance the hydrolysis rate and decrease the activation energy of magnesium hydride during hydrogen generation.
