Caprolactone CAS 502-44-3
Caprolactone monomer is a colorless liquid with low viscosity. The lactone ring is relatively easy to open and contains active hydrogen atoms.
6-Caprolactone is a colorless oily liquid with aromatic odor, unstable, flammable, easy to polymerize, and becomes a dimer when heated.
ULI-ECO provides technology-leading Caprolactone fully biodegradable materials.
6-Caprolactone is a colorless oily liquid at normal temperature and pressure, with a special aroma of ester. Its molecule contains a five-membered lactone ring and an alkyl side chain. Because the carbonyl group and epoxy group on the lactone ring fix the structure of the molecule, the molecule of 6-caprolactone shows strong stability and inertness. At the same time, the presence of alkyl side chains makes 6-caprolactone have better solubility and compatibility in solvents. Since the molecule of 6-caprolactone contains a carbonyl group, it has certain reactivity and can undergo various chemical reactions such as esterification, addition, and nucleophilic substitution.

Caprolactone is a new type of polyester monomer, mainly used in the production of synthetic rubber, synthetic fiber and synthetic resin; it is also used in the manufacture of caprolactam, adipic acid, adhesives, coatings, epoxy resin thinners and solvents; it can also be used Blended with various resins to improve its gloss, transparency and anti-adhesive properties. Some customers provide information, which can be used in medical materials, simulating human skin, etc., and can also be used to make polycaprolactone, ε-caprolactam, adhesives, elastomers, etc.
Features and Benefits
Caprolactone is a colorless oily liquid with aromatic odor, unstable, flammable, easy to polymerize, and becomes a dimer when heated. Boiling point 215-216°C, 96-97.5 (1.33kPa), 98-99°C (266.644Pa), relative density 1.0693 (20/4°C), refractive index 1.4495, ignition point 127°C, freezing point -18°C. It is easy to react with organic nitrogen compounds. It should not be in contact with inorganic acids, organic acids, alkalis, acidic and basic salts, water and water vapor during storage, nor should it be close to copper and zinc. Nitrogen gas is required for storage, and a small amount of nitrite stabilizer is added.
In perfect packaging, it was not delivered until shortly before use. At all times, storage areas should be covered and protected from above ambient temperature.
For bulk storage tanks, special consideration needs to be given to cleanliness, materials of construction and preventing air from entering the tank. Technical advice on storage tanks is available upon request.
