PHYSICAL CHEMICAL
AND PROPERTIES
M o l e c u l a r W e i g h t : 53.50 S o l u b i l i t y in w a t e r : 2 0 % at -13°C, 2 5 % at 10°C, 3 0 % at 33°C, 4 0 % a t 8 3 ° C Strongly endothermic (lowers solution temperature upon dissolving). Aqueous solubility suppressed by sodium chloride. Slightly soluble i n methyl and ethyl alcohol a n d acetone. Fair solubility in glycerine. M e l t i n g Point: Sublimes. p H o f Solutions: 25°C: 1 % 5.5, 3 % 5 . 1 , 10% 5.0 (technical grade). A p p e a r a n c e : White crystals, practically 100% w i l l pass through a No. 20 screen. Reactions: Decomposed i n solution by strong alkalies to liberate ammonia Reacts with nitrites to form nitrogen. Reported t o reduce oxides of cobalt a n d nickel at high temperatures. Hydrox ides of nickel, zinc, cadmium and manganese reported t o be more soluble i n water in presence of ammonium chloride. Acid characteristics cause acceleration of set of urea-formaldehyde resins. Q u a l i t y : Principal impurity is sodium chloride. Very low i n metallic impurities. Technical grade better than 9 9 % NH 4 CI.

I n batteries, it's a strong electrolyte. In bricks, it prevents "black-coring" by reacting with clay pyrites. In bread dough, it increases yeast action. SOLVAY Ammonium Chloride plays varied, vital parts in these, and many fields. In urea formalde hyde resins and adhesives, it speeds polymerization. On ski slopes, it slows melting. Other key uses are in textile and fur dyeing, compounding of "tanners bate" for leather, low-cost fireproofing of paper and textiles, flux for galvanizing and soldering, casting sealer for foundries.
