ECHEMI Editorial Reference

COLOURLESS-TO-YELLOW LIQUID WITH PUNGENT ODOUR.
Pyrrolidine, also known as tetrahydropyrrole, is an organic compound with the molecular formula (CH2)4NH. It is a cyclic secondary amine, also classified as a saturated heterocycle. It is a colourless liquid that is miscible with water and most organic solvents. It has a characteristic semen-like odor. Compared to acyclic secondary amines, it is about 10 times more basic.
Pyrrolidine appears as a colorless to pale yellow liquid with an ammonia-like odor. Vapors heavier than air. Produces toxic oxides of nitrogen during combustion.|Liquid|COLOURLESS-TO-YELLOW LIQUID WITH PUNGENT ODOUR.|Colourless liquid; Penetrating amine-type aroma
Pyrrolidine appears as a colorless to pale yellow liquid with an ammonia-like odor. Vapors heavier than air. Produces toxic oxides of nitrogen during combustion.|Pyrrolidine is a cyclic amine whose five-membered ring contains four carbon atoms and one nitrogen atom; the parent compound of the pyrrolidine family. It is a saturated organic heteromonocyclic parent, a member of pyrrolidines and an azacycloalkane. It is a conjugate base of a pyrrolidinium ion.

Handling and Storage

Precautions for safe handling

NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Use non-sparking handtools. Prevent build-up of electrostatic charges (e.g., by grounding). Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Conditions for safe storage, including any incompatibilities

Fireproof. Separated from strong oxidants and acids. Well closed.Bundling and sills should be provided to prevent spread of liquid accidentally escaping from storage and process vessels.
