DESCRIPTION
Isobutylene for Industrial
Isobutylene is colorless gas, can form explosive mixtures with air, soluble in organic solvent, explosion limit of 1.7% ~ 1.7%, easily be aggregated, constitutional formula CH3=C(CH3)2.
Isobutylene is an important chemical raw material, mainly used for the preparation of butyl rubber, polyisobutylene, methacrylonitrile, antioxidants, tertiary butyl phenol, tert-butyl ether, etc.
Typical Properties
Summary
Isobutylene is a colorless gas with a faint petroleum-like odor. For transportation it may be stenched. It is shipped as a liquefied gas under its own vapor pressure. Contact with the liquid can cause frostbite. It is easily ignited. Its vapors are heavier than air and a flame can flash back to the source of leak very easily. The leak can either be a liquid or vapor leak. It can asphyxiate by the displacement of air. Under prolonged exposure to fire or heat the containers may rupture violently and rocket. It is used in the production of isooctane, a high octane aviation gasoline.
