Uses and synthesis of Azodicarbonamide powder

1. Azodicarbonamide powder is white or light yellow powder. Melting point >180°C (decomposition), relative density 1.66 (20/4°C).
2. Azodicarbonamide CAS 123-77-3 Soluble in alkali, insoluble in acid, alcohol, gasoline, benzene, pyridine and water.

Above 120℃, it is easy to decompose and release a large amount of nitrogen, Azodicarbonamide Raw Materials is easy to cause explosion in closed containers.

Applications / Functions of Azodicarbonamide powder

• Azodicarbonamide powder can be used in low dosage for the safe and rapid oxidation of wheat flour to improve the physical properties of the dough and the organisation required for high gluten doughs.
• Azodicarbonamide CAS 123-77-3 As a flour treatment agent, it can be used in wheat flour under the regulations of our country, and the maximum use amount is 0.045g/kg.
• Azodicarbonamide powder is widely used in a variety of synthetic materials such as polyvinyl chloride, polyethylene, ethylene vinyl acetate copolymers, polypropylene, polystyrene, ABS, nylon-6, and neoprene rubber, and there is no product that can compete with it so far.
• 

Azodicarbonamide Raw Materials are widely used for foaming polyvinyl chloride, polyethylene, polypropylene, ABS resin and rubber.

Physicochemical Property of Azodicarbonamide powder

Yellow powder. Odourless. Azodicarbonamide CAS 123-77-3 Soluble in alkali and dimethyl sulfoxide, insoluble in alcohol, gasoline, benzene, pyridine and water.

Production methodprocess of Azodicarbonamide powder

Dissolve urea in 2% hydrazine hydrate solution, stir, and add sulfuric acid, so that the Ph value of 1 to 2, and then heated to make the Ph value of 2 to 5, and then slowly add sulfuric acid, to maintain the Ph value of 2 to 5, the reaction for a few hours to determine the end point of the sample; after the reaction is complete, filtration to remove the mother liquor of ammonium sulphate, and washed with hot water to get the bifidicarbonamide.

Dissolve bis(carbamide) in water, add sodium bromide, pass chlorine gas, react at 30~50℃; the reaction mixture is washed with warm water to neutral, then centrifuged and dried to get Azodicarbonamide CAS 123-77-3.

Each ton of Azodicarbonamide powder consumes hydrazine hydrate (40%) 1160kg, urea 1330kg, liquid chlorine 800kg, caustic soda (30%) 2000kg, sulfuric acid (98%) 1140kg.
