Ammonium Chloride 12125-02-9

Ammonium chloride, or ammonium chloride for short. It refers to the ammonium salt of hydrochloric acid, which is mostly a by-product of the alkali industry. Contain nitrogen 24% ~ 26%, show white or slightly yellow square or octahedron small crystal, there are two dosage forms of powder and granular, granular ammonium chloride is not easy to absorb moisture, easy to store, and powder ammonium chloride is more used as the basic fertilizer for the production of compound fertilizer. As a physiological acid fertilizer, it is not suitable to be applied on acidic soil and saline-alkali soil due to its high content of chlorine. It is not suitable to be used as seed fertilizer, rice field fertilizer or leaf fertilizer, nor should it be applied on chlorine-free crops (such as tobacco, potato, citrus, tea tree, etc.). Ammonium chloride has a higher and stable fertilizer efficiency in paddy fields, because C1 can not only inhibit nitrification in the paddy field, but also facilitate the formation of fiber in rice stalks, increase toughness, and reduce rice lodging and invasion by diseases and insects.

Colorless crystal or white granular powder, is a strong electrolyte, dissolved in water to separate ammonium and chloride ions, ammonia and hydrogen chloride combined to produce ammonium chloride white smoke. No smell. It was salty, cool and slightly bitter. Hygroscopicity is small, but in wet rainy weather can also absorb moisture agglomerate. Powdery ammonium chloride is easy to deliquescence, qualified products especially, the moisture absorption point is generally around 76%, when the relative humidity in the air is greater than the moisture absorption point, ammonium chloride is the phenomenon of moisture absorption, easy to agglomerate. Can sublimate (actually the decomposition and regeneration of ammonium chloride) without melting. Relative density 1.5274. Refractive index 1.642. Low toxicity, median lethal dose (rat, oral) 1650mg/kg. It's irritating. Heating to 350℃ sublimation, boiling point 520℃
