| 1-Methylpyrrolidine Usage And Synthesis |
| Chemical Properties | colorless transparent volatile liquid. Freely soluble in water, soluble in alcohol, ether and other organic solvents. | | Uses | 1-Methylpyrrolidine is a methylated pyrollidine and is involved as an essential part of the structure of cefipime. It is also an active component of cigarette smoke. | | Preparation | n-methylpyrrolidine was successfully synthesized in an aqueous medium by using methylamine and 1,4-dibromobutane in the presence of catalyst k2co3 at a moderated temperature. here, n-methylpyrrolidine was firstly synthesized via the green chemistry process, in which both the water solvent and potassium carbonate catalyst were inexpensive and environmentally friendly. also, the reaction temperature was quite moderated at 90°C.green organic synthesis of n-methylpyrrolidine | | Hazard | Flammable, dangerous fire risk. Irritant toskin and eyes. | | Flammability and Explosibility | Highlyflammable | | Safety Profile | Poison by
intraperitoneal and intravenous routes. This
material is strongly alkaline. Liquid and
vapors are corrosive to the skin, eyes, or
mucous membranes. A very dangerous fire
hazard; keep away from sparks, heat
sources, and powerful oxidizers. Keep in
closed containers. To fight fire, use alcohol
foam. When heated to decomposition it
emits highly toxic fumes of NOx. |
