Description and Uses

Hexene is a colorless liquid. Molecu larweight= 84.14;Boiling point= 63-65℃;Freezing/Melting point=一140℃; Flash point= - 7℃; Autoignitiontemperature = 253℃. Explosive Limits:LEL= 1.2%;UEL= 6.9%. Hazard Identification (based on NFPA-704 MRating System): Health 1, Flammability 3, Reactivity 0.Insoluble in water.

1-Hexene is used as a solvent, paint thinner and a medium for conducting chemical reactions. It is a commoner and used in the preparation of both low density and high density polyethylenes. It acts as an adhesives, lubricants, lubricant additives and sealant chemicals. Further, it is used in the preparation of hex-1-en-3-one, heptanal and heptanoic acid. It is also employed in the synthesis of linear plasticizers, oxo-alcohols, motor fuels, automotive additives and biodegradable surfactants. In addition to this, it is used in the preparation of mercaptans, flavors and fragrances, alkyl metals, halides and alkyl silanes.
