4-비닐피리딘 C화학적 특성, 용도, 생산
화학적 성질
dark brown to yellow liquid. 2.9g can be dissolved in 100g of water at 20℃, soluble in methanol, ether, benzene, acetone, and slightly soluble in ether. When exposed to light and heat, polymerization occurs, and 0.1%-0.2% hydroquinone is often added as a polymerization inhibitor during storage.용도
4-Vinylpyridine acts as a co-monomer in styrene-butadiene polymers to promote adhesion between the rubber compound and supporting fibers (or cords) in tires, belts and hoses. It serves as an intermediate for manufacturing chemicals and pharmaceuticals. Further, it is used as a reagent for the modification of cysteine. In addition to this, it is used to make poly(4-vinylpyridine) and elastomers.제조 방법
4-Vinylpyridine is synthesized by reacting 4-picoline with formaldehyde to generate 4-pyridineethanol, which is then dehydrated.주요 응용
4-Vinylpyridine was used as a monomer in polymer chemistry and induced nonimmunological contact urticaria and allergic contact dermatitis. No crossreactivity is observed between pyridine derivatives. It can be copolymerized with many other monomers, in particular cationic monomers, such as acrylamide, acrylates, and also with other vinyl-based monomers (e.g. styrene).?Purification Methods
6 2 . Purify the monomer by fractional distillation under a good vacuum and in a N2 atmosphere and store it in sealed ampoules under N2, and keep it in the dark at -20o. The picrate has m 175-176o.
