N-ethylpyrrolidone (NEP) is the lactam of 4-ethylaminobutyric acid and a very weak base. NEP is a chemically stable and powerful polar solvent. These characteristics are highly useful in a variety of chemical reactions where an inert medium is of concern. Despite the stability of NEP, it can also play an active role in certain reactions: hydrolysis, oxidation, condensation, conversion with chlorinating agents, polymerization and o-alkylation, and related reactions.
APPLICATIONS:
petrochemical applications
synthetic plastic elements
extraction/recovery of acetylene and butadiene
dyeing fibers and leather
synthesis medium for high MW. polymers
dehydration of natural gas
synthetic fiber spinning medium
pesticides
pigment dispersions
lube oil processing
PACKING:
200kgs plastic drum.
SAFETY:
Care should be used when handling NEP. Skin contact should be avoided. Contact can result in irritation; prolonged contact can result in redness and dermatitis. Butylrubber or FEP Teflon gloves are recommended when handling NEP. A good skincream should be used after washing the affected area. As with all solvents, the workplace should be well ventilated and safety goggles must be worn.
STORAGE & HANDLING:
NEP has an almost unlimited shelf life in sealed containers when properly stored in a protected storage area in original unopened containers or protected from moisture. It is neither explosive nor spontaneously flammable in air. However, it is combustible. When ignited, NEP will sustain a fire. All types of fire extinguishers are effective against NEP fires.
