| 2-Vinylpyridine Usage And Synthesis |
| 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. | | Chemical Properties | dark brown liquid with an unpleasant odour | | Uses | 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). | | Uses | 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. | | 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 | | 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.] |
