ε-Caprolactone Chemical Properties,Usage,Production

Chemical Properties

Clear colorless liquid, yellowing on ageing

Uses

Intermediate in adhesives, urethane coatings, and elastomers; solvent; diluent for epoxy resins; synthetic fibers; organic synthesis.

Uses

ε-Caprolactone is widely used as a monomer in the manufacturing of highly specialized polymers. It is mainly utilized as a precursor to caprolactam. It finds an application in the synthesis of polyglecaprone, which is used as a suture material in surgery.

Uses

ε-caprolactone is popularly used in the preparation of poly caprolactone (PCL).

Definition

ChEBI: A epsilon-lactone that is oxepane substituted by an oxo group at position 2.
