Is isobutene and isobutylene same?
Isobutene and Isobutylene are the same chemical.
Is isobutylene heavier than air?
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. Its vapors are heavier than air and a flame can flash back to the source of leak very easily.
Why is isobutylene more stable?
Isobutylene is more stable than butene due to steric inhibition . The structure of isobutylene resist to attack incoming atoms or molecules . But butene is in linear form and foreign atoms or molecules can easily be attacked. Therefore butene is less stable than isobutylene.

Is isobutylene a gas or liquid?
Isobutylene is a flammable gas with a reported vapour pressure of 2,9732 hPa (25 °C); a water solubility of 263 mg/l (25 °C), a log Kow of 2.34, a melting point of –140.4°C, a boiling point of –6.9°C and a density of 0.588 g/cm3 (25°C).
Why is isobutene more stable than 2-butene?
More branched hydrocarbons are stable than the lesser branched ones. Isobutene is chemically 2-methylpropene and thus a branched structure. Butene is a straight chain structure. This is why Isobutene is more stable than Butene.
How is isobutylene made?
Production. Polymer and chemical grade isobutylene is typically obtained by dehydrating tertiary butyl alcohol (TBA) or catalytic dehydrogenation of isobutane (Catofin or similar processes).
Where is isobutylene used?
Isobutylene is used in the production of a variety of products. It is alkylated with butane to produce isooctane or dimerized to diisobutylene (DIB) and then hydrogenated to make isooctane, a fuel additive. Isobutylene is also used in the production of methacrolein.
What is the chemical formula for isobutylene?

What is polypoly (isobutylene)?
Poly (isobutylene) is manufactured in a wide range of molecular weights, ranging from 45 000 to 2 110 000. A common form of butyl-based sealant is the form of a tape. This tape is coated onto release paper and rolled on a core. The tape can be formulated to have a certain amount of tack.
What is the molecular weight of butyl sealant?
