Introduction to 2-Vinylpyridine

2-Vinylpyridine, also known by its CAS number 100-69-6, is a chemical compound with the molecular formula C7H7N. It is a derivative of pyridine and is characterized by a vinyl group attached to the 2-position of the pyridine ring. This compound is known by several aliases, including 2-Ethenylpyridin, 2-Ethenylpyridine, 2-Ethenylpryridine, vinyl-pyridine, 2-Vinylpyridine, Pyridine,2-ethenyl, 2VP, T6NJ B1U1, α-Vinylpyridine, Pyridine,2-vinyl, 2-Pyridylethylene, Pyridine, 2-ethenyl-, 2-ethenyl-pyridin, 2-vinyl-pyridin, Pyridine, ethenyl-, and pyridin-2-ylethylene. As a key intermediate in the chemical industry, 2-Vinylpyridine plays a crucial role in the synthesis of various polymers and other chemical products.

Chemical Properties and Characteristics

2-Vinylpyridine is a colorless to light yellow liquid with an aromatic odor. It has a melting point of -51°C and a boiling point of 159-160°C. The compound is slightly soluble in water but readily dissolves in organic solvents such as ethanol, ether, chloroform, benzene, and acetone. Its density is approximately 0.9788 g/cm³ at room temperature, and it has a refractive index of 1.5495 at 20°C. 2-Vinylpyridine is known to be lachrymatory and toxic, and it can polymerize under the influence of light or heat. To prevent polymerization during storage, it is often stabilized with a small amount of 4-tert-butylcatechol.

Production Processes

There are two primary methods for the production of 2-Vinylpyridine. The first method involves the reaction of 2-methylpyridine with formaldehyde to form 2-hydroxyethylpyridine, which is then dehydrated to yield 2-Vinylpyridine. This process is carried out at high temperatures and pressures, with the reaction mixture being treated with sodium hydroxide to facilitate dehydration. The second method utilizes the reaction of acetylene with acrylonitrile in the presence of a cobalt catalyst. This process operates at moderate temperatures and pressures, resulting in high yields of 2-Vinylpyridine.

Applications and Uses

2-Vinylpyridine is widely used in the production of polymers and copolymers. One of its primary applications is in the manufacture of butadiene-styrene-vinylpyridine latex, which is used for impregnating rayon, nylon, and polyester cords or fabrics. This latex enhances the adhesive properties of the materials, making them suitable for use in high-strength tires, pressure-resistant hoses, conveyor belts, and hiking boots. In the pharmaceutical industry, 2-Vinylpyridine is used in the production of film-coating materials for tablets, offering advantages over traditional sucrose coatings by preventing moisture deterioration and cracking. Additionally, it is employed in the synthesis of pesticides such as paraquat and imidacloprid, which are significant products in the agricultural sector.

Safety and Handling

Due to its toxic and lachrymatory nature, 2-Vinylpyridine requires careful handling and storage. It is classified as a hazardous substance, and exposure should be minimized. Protective equipment, including gloves, goggles, and respiratory protection, should be used when handling the compound. In case of accidental exposure, immediate medical attention is recommended. Storage should be in a cool, well-ventilated area, away from sources of ignition and incompatible materials such as strong oxidizing agents, strong bases, and strong acids.
