The Uses of 1-Ethyl-2-pyrrolidone

1-Ethyl-2-pyrrolidone was used to modify coir fiber (from Cocos nucifera) by photocuring.

What are the applications of Application

N-Ethyl-2-pyrrolidone is commonly used as a solvent. It has a low boiling point, which makes it suitable for use in low light and at constant pressure. It is also used as an intermediate in the preparation of polycarboxylic acid. It has been shown to be involved in both viscosity and hydrogen bonding.

Definition

ChEBI: 1-Ethyl-2-pyrrolidinone is a N-alkylpyrrolidine.
