Isobutylene - Wikipedia
Isobutylene (or 2-methylpropene) is a hydrocarbon with the chemical formula (CH3)2C=CH2. It is a four-carbon branched alkene (olefin), one of the four isomers of butylene. It is a colorless flammable gas, and is of considerable industrial value. [3]
Isobutylene | C4H8 | CID 8255 - PubChem
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.
Isobutane - Wikipedia
Isobutane, also known as i-butane, 2-methylpropane or methylpropane, is a chemical compound with molecular formula HC (CH 3) 3. It is an isomer of butane. Isobutane is a colorless, odorless gas. It is the simplest alkane with a tertiary carbon atom.

在室温和大气压下，异丁烯是一种无色可燃气体，有类似煤气的臭味。 以工业异丁烯为原料 (异丁烯99%)，经干燥脱水、精馏提纯即可。 高纯异丁烯主要用作标准气及配制特种标准混合气。 异丁烯对黏膜有轻微的刺激作用，对人体有麻醉作用。 吸入高浓度异丁烯会产生窒息效应。 皮肤接触液态异丁烯可引起冻伤。 异丁烯的毒性为乙烯的4.5倍。 最高容许浓度：400×10_6。 气瓶要存放在阴凉通风良好之处，要远离热源和火种，要与氧、氯、高氧化性和易燃性物质隔离。 所有 …
Isobutene - BASF
Isobutene (Isobutylene) is produced in a subsequent stage after cracking naphtha in the BASF Steamcracker. It is an unsaturated hydrocarbon which is used in various application areas of the chemical industry. For example as a raw material for butyl rubber and for polyisobutylene.
Isobutylene | chemical compound | Britannica
The best-known dienes are butadiene and isoprene, used in the manufacture of synthetic rubber. Olefins containing two to four carbon atoms per molecule are gaseous at ordinary temperatures and pressure; those containing five or more carbon atoms are usually liquid at ordinary temperatures. Olefins are only slightly soluble in water.
Isobutene - Air Liquide Gas Encyclopedia
Isobutylene (or isobutene) is the feedstock for production of polybutene (butyl rubber). Isobutene is an intermediate in the manufacturing of methyl terbuthyl ether (MTBE).
