Description of key information
Without a polymerisation inhibitor present, liquid 2VP can autopolymerize, with potential self-heating, pressure rise and rupture of containers. When volatilised, 2VP is unstable in the presence of atmospheric radicals, and rapidly reacts to form aldehydes and other derivatives.
Additional information
Commercial 2-Vinylpyridine is stabilised by the addition of a polymerisation inhibitor, such as tert-butylcatechol (1000 ppm). 2VP can undergo a self-accelerating polymerisation reaction to form poly-vinylpyridine when heated in a closed container, when water is absorbed, or when impurities are introduced to consume the stabiliser. This reaction is exothermic and can cause a significant increase in heat and pressure, which can result in splitting of the container with consequences including fire.
When volatilised, 2VP is unstable in atmospheric conditions where hydroxyl and nitrate radicals and ozone are present. The primary reaction product is 2-pyridinecarboxaldehyde. For ambient atmospheric conditions, the calculated half-lives of 2VP due to the reaction with OH radicals and O3 are 1.5 hours, 2 hours and 12 hours, respectively. This indirect photolysis reaction is analogous to the photochemical breakdown of styrene to benzaldehyde, a well-known atmospheric fate pathway.Justification for classification or non-classification
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
