Properties and stability

Storage stable. Non-toxic. It will decompose at lower temperatures in acidic media, and the decomposition products are harmful to the human body. Production equipment should be sealed, and ventilation and exhaust should be strengthened at the production site. Operators should wear protective equipment.

Storage method

Should be sealed and stored in a ventilated, cool, dry place, and be protected from moisture and heat. It cannot be stored or transported together with acid or acidic substances.

Synthesis method

Put aniline and azobenzene chloride into the reactor at a mass ratio of 1:1.46, add water and stir to dissolve, then add an appropriate amount of sodium acetate as a catalyst, raise the temperature to 35°C, react with stirring for 1 hour, and then heat The temperature was raised to 65°C and reacted for 6 hours. The hydrogen chloride gas generated during the reaction is absorbed with water to obtain hydrochloric acid as a by-product. After the reaction solution is allowed to stand for 10 hours, sodium chloride is added to salt out to precipitate azoaminobenzene, and then is filtered and dried at low temperature to obtain the finished product.


Complex titration indicator. Precipitating agent for palladium and copper. Determination of palladium and copper and separation from other ions. This product is used as a foaming agent for various rubbers and resins. Such as polyvinyl chloride and its copolymers, polystyrene, polyethylene, phenolic resin, epoxy resin, raw rubber and rubber, silicone polymers, etc. The dosage is 0.1%~5.0%. This product is also used as a polymerization initiator and accelerator for raw rubber.
