Heating of ammonium carbonate

Introduction: ammonium carbonate can be used as raw materials for baking powder, various ammonium salts, buffers, printing and dyeing auxiliaries, fertilizers and analytical reagents, etc., so what is produced by heating ammonium carbonate? Let's take a look at it with Xiaobian Ammonium carbonate is widely used in the production of medicine, pesticide, fire extinguishing agent, detergent, rubber, fermentation, fertilizer, wool refining, electronic components, etc it is a valuable ammoniator, so what does ammonium carbonate generate when heated? Let's learn about it with the safety net Ammonium carbonate is not a precipitate It is soluble in water and is a strong electrolyte After dissolving in water, it is completely ionized: (NH4) 2CO3 = = 2nh4 + + CO3 ^ 2-ammonium carbonate is heated and decomposed to produce ammonia gas, carbon dioxide and water vapor The equation is: (NH4) 2CO3 = = △ = = 2nh3 ↑ + CO2 ↑ + H2O ↑ brief introduction of ammonium carbonate, chemical formula (NH4) 2 · CO3 Colorless cubic crystal, usually containing 1 molecule crystal water; soluble in water, the aqueous solution is alkaline Insoluble in ethanol, carbon disulfide and concentrated ammonia water Unstable in the air, it will gradually become ammonium bicarbonate and ammonium carbamate The dry matter is easy to decompose at 58 ℃, releasing ammonia and carbon dioxide At 70 ℃, the aqueous solution began to decompose Unstable to light and heat Slightly hygroscopic The property of ammonium carbonate is colorless, translucent, hard crystal block or powder Strong ammonia odor Spicy It is a mixture of ammonium bicarbonate (NH4HCO3) and ammonium carbamate (nh2coonh4) The reaction is alkaline In the air, ammonia and carbon dioxide are decomposed to form opaque ammonium bicarbonate powder, which volatilizes completely at 60 ℃ It can slowly dissolve in 4 parts of water It decomposes in hot water The ammonium carbamate can be dissolved in ethanol It's irritating The above is the introduction of what is generated by heating ammonium carbonate If you need to know more about industrial naphthalene and other small knowledge, please continue to pay attention to the food safety common sense column of Baibai safety net Editor in charge: Wang Xiaoli
