What is 2-Vinylpyridine?

Chemical properties

dark brown liquid with an unpleasant odour

Chemical properties

The odor of 2-vinylpyridine can be detected at exposure levels below 1 ppm (v/v). The unpleasant odor can be tolerated at concentrations that can produce acute symptoms and irritation. Special precautions should be taken to avoid skin and eye contact, as well as inhalation of the vapor.

The Uses of 2-Vinylpyridine

2-Vinylpyridine is a pyridine deriviative used in the preparation of poly(2-vinylpyridine) via radical polymerization. 2-Vinylpyridine is used to improve effectiveness of protective polymer coatings o n metals. 2-Vinylpyridine is an impurity of Betahistine (B324000).

The Uses of 2-Vinylpyridine

2-Vinylpyridine is a pyridine derivative used in the preparation of poly(2-vinylpyridine) via radical polymerization. 2-Vinylpyridine is used to improve effectiveness of protective polymer coatings on metals. It is a reagent for pyridylethylation for new protection method for active hydrogen compounds.. It is also used as basic materials for one of largest-selling plastic, manufacturing pharmaceuticals and bio-compounds.

What are the applications of Application

2-vinylpyridine is except being used for fourth pyrrole (butylbenzene pyrrole) latex of synthetic widespread use, and also synthetic etc. for other polymer modification, ion exchange resin, dyeing and printing auxiliary, medicament.

General Description

2-Vinylpyridine (2VP) is a water soluble pyridine derivative that can be used in the synthesis of poly(2-vinylpyridine) (P2VP) by anionic polymerization. It can be industrially prepared by treatment of 2-methylpyridine with an aqueous solution of formaldehyde in a temperature range of 150-200°C.

Flammability and Explosibility

Flammable

Synthesis

The 2-vinylpyridine is mainly prepared from 2-picoline and formaldehyde. The process for synthesizing the 2-vinylpyridine comprises 'two-step' and 'one-step' production processes, and comprises the steps of condensing 2-picoline and formaldehyde to produce hydroxyethyl pyritine; and dehydrating the hydroxyethyl pyritine at a certain temperature in the action of a catalyst to generate the 2-vinylpyridine. The 'one-step' production process is adopted, 2-vinylpyridine is further generated at a certain temperature under the action of an acid catalyst by adopting 2-picoline and formaldehyde as raw materials, the process flow is simple, and the yield is high.

Carcinogenicity

No definitive information on carcinogenicity of the vinylpyridines was found. However, when either 2-vinylpyridine or 4-vinylpyridine was injected intraperitoneally into A/J mice (200 mmol/animal), there was no significant increase in lung adenoma or any other tumors. None was listed as a carcinogen by IARC, OSHA, NTP, and ACGIH.

Purification Methods

Steam distil it, then dry it with MgSO4 and distil it in a vacuum. [Beilstein 20 H 256, 20 III/IV 2884, 20/6 V 211.]
