3682-94-8 Usage
Uses
Used in Polymer Production:
2,2'-Azobis(propane-2-carboxamide) is used as a radical initiator for the polymerization of monomers such as acrylics, vinyl acetate, and styrene. Its ability to generate free radicals at high temperatures facilitates the formation of polymer chains, making it an essential component in the production of these materials.
Used in Plastics Industry:
In the plastics industry, 2,2'-Azobis(propane-2-carboxamide) is utilized as a blowing agent. This application takes advantage of its decomposition properties to create foamed plastics, which are lighter and have unique physical properties compared to their non-foamed counterparts.
Used in Rubber and Elastomers Production:
2,2'-Azobis(propane-2-carboxamide) also serves as a cross-linking agent in the production of rubber and other elastomers. The free radicals it produces help in forming the cross-links between polymer chains, which are crucial for the strength and elasticity of the final product.
Safety Considerations:
It is important to handle 2,2'-Azobis(propane-2-carboxamide) with caution due to its classification as a hazardous substance. Exposure may lead to skin and eye irritation, and respiratory issues if inhaled, necessitating proper safety measures during its use in industrial applications.
Check Digit Verification of cas no
The CAS Registry Mumber 3682-94-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,8 and 2 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3682-94:
(6*3)+(5*6)+(4*8)+(3*2)+(2*9)+(1*4)=108
108 % 10 = 8
So 3682-94-8 is a valid CAS Registry Number.

Synthesis and characterization of new surface active azo initiators for radical reactions
Sedlak, Milos,Tauer, Klaus
, p. 730 - 736 (2007/10/03)
The synthesis of a water soluble azo initiators from 2,2′- azodiisobutyronitrile (AIBN) was performed in three steps: reaction of dinitrile with aromatic alcohols in the presence of HCl to form bisiminoesters hydrochlorides which are hydrolyzed to the esters and final regioselective sulfonation of the aromatic esters. The thermal decomposition of the azo initiators obtained leads to formation of two surface active radicals which can start the chain reaction.
