AIBN structure
AIBN is a symmetrical molecule made up of two 2-cyanoprop-2-yl groups joined by an azo group and it has a nitrile structure, which means that it has cyanide groups (an organic group formed by a carbon and a nitrogen joined by a triple covalent bond).
AIBN azobisisobutironitrile CAS 78-67-1 Usages
Azobisisobutyronitrile (AIBN), with the CAS number 78-67-1, is commonly employed as a radical initiator in several chemical processes. Below are few primary applications of AIBN:
1. AIBN is primarily employed as a free radical initiator in the polymerization process of different monomers, including acrylics, methacrylics, and vinyl compounds. It facilitates the commencement of the radical polymerization process, resulting in the creation of polymers such as polyacrylamide and poly(methyl methacrylate).
2. Research and Development: AIBN is employed in research laboratories to investigate polymerization processes and create new polymers. The regular generation of free radicals makes it well-suited for controlled polymerization operations.
3. AIBN is utilised in organic synthesis as a radical source, extending beyond its role in polymerization. The use of AIBN-derived radicals can initiate a wide range of chemical processes, such as halogenations and the incorporation of radicals into alkenes.
4. AIBN can function as a foaming agent in the manufacturing of foamed plastics. It aids in the formation of gas bubbles that are essential for creating the foam structure in plastics.
5. AIBN is utilised in the production of photostabilizers, which are substances incorporated into plastics and other materials to safeguard them against deterioration caused by ultraviolet radiation.
6. Chemical research involves the utilisation of experiments and mechanistic studies in the study of chemistry, specifically to get a better understanding of reactions caused by radicals.
The uses of AIBN emphasise its vital role in both industrial manufacture and scientific research, where its ability to generate radicals is extensively utilised.
