2-피로리딘온,1-에테닐- C화학적 특성, 용도, 생산
화학적 성질
Colorless liquid. Combustible.용도
A pyrrolidine used for biochemical research일반 설명
1-Vinyl-2-pyrrolidinone is a colorless to yellow liquid, with a characteristic odor. Its melting point is around 13.5oC and boils at about 90-92oC. VP is completely miscible in water and in most organic solvents but partially miscible in aliphatic hydrocarbons. Industrial production of VP by reacting 2-pyrrolidone with acetylene at high pressure and temperature has been reported. The vinylation process proceeds in liquid phase and is catalyzed by 3-pyrrolidone -potassium hydroxide.화학 반응
N-Vinyl-2-pyrrolidone (NVP) is stable toward alkalis at room temperature. Above 0 ℃ it is cleaved by aqueous mineral acids into acetaldehyde and 2-pyrrolidone; the latter reacts with an excess of NVP to give 1,1'-ethylidene-bis-2- pyrrolidone. Protic compounds such as amides, thiols, alcohols, and phenols add to the double bond according to the Markovnikov rule, for example, N-(1-phenoxyethyl)-2-pyrrolidone is formed with phenol. Catalytic hydrogenation produces N-ethyl-2-pyrrolidone. Hydroformylation on rhodium catalysts forms 2-N-(2-pyrrolidonyl)-propanal as the major product. On prolonged standing, particularly in warm conditions, NVP tends to polymerize. Industrially, N-Vinyl-2-pyrrolidone (NVP) is converted into polyvinylpyrrolidone using radical initiators.Safety Profile
Confirmed carcinogen. Moderately toxic by ingestion, inhalation, and skin contact. A severe eye irritant. Probably irritating and narcotic in high concentrations. Combustible when exposed to heat or flame; can react vigorously with oxibzing materials. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits highly toxic fumes of NOx.2-피로리딘온,1-에테닐- 준비 용품 및 원자재
