Vinylpyridine Uses
2-Ethenylpyridine (1337-81-1) contains additives to prevent unwanted rapid polymerization.
Vinylpyridine Production
May nevertheless polymerize exothermically if subjected to heat for prolonged periods or if contaminated. If polymerization takes place inside a closed container, the container may violently rupture. May polymerize upon contact with peroxides and with compounds partially peroxidized by exposure to the air [Bretherick 1979 p. 160]. Reacts with oxidizing agents [Handling Chemicals Safely, 1980 p. 960]. Neutralizes acids in exothermic reactions to form salts plus water. Incompatible with isocyanates, halogenated organics, phenols (acidic), epoxides, anhydrides, and acid halides. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides.
Vinylpyridine Safety Profile
Spontaneous polymerization may be explosive. When heated to decomposition it emits toxic fumes of NOx.
