1-Methylpyrrolidine Chemical Properties,Uses,Production

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

Highly flammable

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.

Synthesis

1-Methylpyrrolidine is prepared by hydrogenation of N-Methylpyrrole over Adams' catalyst.
