Molecular formula: (NH₄)₂CO₃
Molecular weight: 96.08
CAS NO.: 506-87-6
Specification: Small lumps, flakes, crushed
Product traits: It is a white translucent hard block or powder composed of ammonium bicarbonate and carbamate (or complex salt). It has a pungent smell of ammonia, soluble in water, but decomposed in hot water (70°C), insoluble in concentrated ammonia and ethanol, and gradually becomes ammonium bicarbonate in the exposed air. When heated at 580°C, it decomposes into ammonia and carbon dioxide.

Molecular formula: NH₂COONH₄
Specification: Small block, flake, crushed
Product traits: "Ammonium carbamate" is an important chemical raw material, widely used in the production of medicines, pesticides, fire extinguishing agents, detergents, rubber, fermentation, fertilizers, wool refining, electronic components, etc. It is a valuable ammoniating agent. Analytical purity and chemical reagents. It can analyze potassium, radium, thorium, etc., and can be used as a chromatographic analysis reagent. It can also evolve into various carbonate products.

Molecular formula: C₄H₆O₃
Molecular weight: 102.09
Product Usage: It can be used as an excellent medium for high-energy batteries and capacitors in the electronics industry, and as a solvent and plasticizer for polymers in the polymer industry. Used as a plasticizer for adhesives and sealants. It can also be used as a phenolic resin curing accelerator and a dispersant for water-soluble adhesive pigments and fillers. The chemical industry is the main raw material for the synthesis of dimethyl carbonate and can also be used to remove carbon dioxide and hydrogen sulfide from natural gas and petroleum cracked gas. In addition: it can also be used in textile, printing and dyeing industries. Packing: 250kg galvanized iron drum, or according to customer requirements.
