Chemical Properties
White solid
Uses
2,2'-azobis(2,4-dimethyl)valeronitrile is widely used in PVC suspension polymerization, it is also used as polyacrylonitrile, polyvinyl alcohol polymer composite materials such as plexiglass efficient initiator, also used as rubber, plastic foam.
General Description
An odorless white solid. May burst into flames upon exposure to fire or high heat. Dust may form an explosive mixture in air.
Air & Water Reactions
Dust may form an explosive mixture in air. Insoluble in water.
Reactivity Profile
Self-decomposition or self-ignition may be triggered by heat, chemical reaction, friction or impact. Self-accelerating decomposition may occur if the specific control temperature is not maintained. 2,2'-Azobis(2,4-dimethyl)valeronitrile is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides.

Check Digit Verification of cas no
The CAS Registry Mumber 4419-11-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,1 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4419-11:
(6*4)+(5*4)+(4*1)+(3*9)+(2*1)+(1*1)=78
78 % 10 = 8
So 4419-11-8 is a valid CAS Registry Number.

METHOD FOR PRODUCING AZO COMPOUNDS
-
Paragraph 0046, (2018/04/14)
PROBLEM TO BE SOLVED: To provide a method that can produce azo compounds at good yields by making oxygen or an oxygen-containing gas act on hydrazo compounds when oxidatively dehydrogenating them. SOLUTION: Azo compounds are produced by making oxygen or an oxygen-containing gas act on hydrazo compounds in the presence of nitrite compounds, bromine compounds and a solvent.
