Ammonium chloride At a low price

Details:

Ammonium chloride is colorless crystal or white crystalline powder;Odourless, taste salty, cool;Have led to wet.This product soluble in water, slightly soluble in ethanol.[1]
Chinese name English name ammonium chloride ammonium chloride don't say AmmoniumChloride chemical formula NH4Cl molecular weight 53.49 CAS login number 12125-02-9 login einecs no. 235-186-4, melting point 340 ° C (subl.) (lit) boiling point 520 ℃ dense degree of 1.527 g/cm3 view white customs said electric, electric powder, salt, refined salt, sal ammoniac electronic please see "introduction" chemical formula NH4ClAqueous solution in weak acid, heating acid enhancement.To black metal and other metal corrosive, especially for copper corrosion more big, the pig iron no corrosive action.

There are two main types of the product production process: one is to use a famous Chinese scientists invented Hou Debang Hou Shi soda, soda ash and ammonium chloride production two products at the same time;The second is the by-product of the production of potassium carbonate potassium.Ammonium chloride is easy to agglomerate, usually with add anticaking agent to prevent product caking.

Mix ammonia and hydrogen chloride gas, there will be a white smoke generated, white smoke is the ammonium chloride.
The heated to:
NH4Cl = = delta = = + HCl NH3 write up this reaction is reversible reaction, both of the substances in the reaction at the same time will combine again for ammonium chloride.
And sulfuric acid reaction:
NH4Cl + - H2SO4 = = = = NH4HSO4 + HCl write

character


Colorless crystals or white granular powder, is a kind of strong electrolyte, soluble in water and electricity from the ammonium ion and chloride ion, combined to generate the ammonia and hydrogen chloride with ammonium chloride white smoke.There is no


Ammonium chloride
Smell.Taste salty, and bitter cold.Moisture absorption, but also in the humid rainy weather can damp agglomerate.Nonconforming product powdery ammonium chloride are easily deliquescence, especially, hygroscopic point is in commonly 76%, when the relative humidity in the air is greater than the hygroscopic point, ammonium chloride which produce phenomenon of moisture absorption, easy to agglomerate.Can sublimate (in fact is the process of decomposition of ammonium chloride and regenerate) without melting point.Relative density 1.5274.The refractive index of 1.642.Low toxicity, median lethal dose (rats, through the mouth) 1650 mg/kg.Stimulating.Heated to 350 ℃ sublimation, the boiling point of 520 ℃.
Soluble in water, slightly soluble in ethanol, soluble in liquid ammonia, insoluble in acetone and ether.Hydrochloric acid and sodium chloride can reduce its solubility in water, its water solubility 29.4 g when 0 ℃, 10 ℃ for 33.2 g, 20 ℃ for 37.2 g, 30 ℃ to 41.4 g, 40 ℃ for 45.8 g, 50 ℃ for 50.4 g, 60 ℃ was 55.3 g, 70 ℃ for 60.2 g, 80 ℃ for 65.6 g, 90 ℃ for 71.2 g, 100 ℃ for 77.3 g).Starts to break down when heated to 100 ℃, 337.8 ℃ can be completely decomposed into ammonia and hydrogen chloride gas, encounter cold again after combined to generate little particles of ammonium chloride and appears as a white smoke, is not easy to sink, also very not easy to dissolve in water.
Aqueous solution of pH: because hydrolysis ionization of ammonium ions in the water make the solution acidity, temperature of saturated ammonium chloride solution pH value generally at about 5.6.25 ℃, 1%, 5.5, 1%, 5.1 10% to 5.0.Ammonium chloride itself can be a stabilizing reagent bismuth, antimony (chlorine ions provide coordination, when using the compounds with ammonium chloride dissolved in dilute hydrochloric acid).

Ammonium chloride can be chemical reaction by ammonia and hydrogen chloride from colorless


Ammonium chloride powder
The crystal or white crystalline powder.NH3 + HCl = NH4Cl laboratory for making ammonia method: 2 NH4Cl + Ca (OH) 2 = CaCl2 + 2 h2o + 2 NH3 write condition is heated.
Ammonia and hydrogen chloride combination reaction occurs when contact: NH3 + HCl = NH4Cl (generating white smoke)
With hydrochloric acid and ammonia neutralization reaction: NH3 · H2O + HCl = NH4Cl + H2O.
When heated and is decomposed into hydrogen chloride and ammonia: NH4Cl = = delta = = NH3 write + HCl write condition is heated.
Ammonium chloride by ammonia and hydrogen chloride and ammonia water and hydrochloric acid neutralization reaction.
