Isobutylene Structure
The chemical formula of isobutylene is C4H8, Isobutylene formula is (CH3)2C=CH2, and it is also known as 2-methylpropene. Isobutene is a colorless gas, insoluble in water, with carbon-carbon double bonds, which can undergo addition polymerization to produce polymer polyisobutene.
Is isobutylene soluble in water?
Isobutylene CAS 115-11-7 is sparingly soluble in water. This means that it has limited ability to dissolve in water. The solubility of isobutylene in water is quite low due to the non-polar nature of the molecule. Water is a polar solvent, while isobutylene is a nonpolar compound, which makes them less likely to mix and form a homogeneous solution.
While isobutylene's solubility in water is limited, it is highly soluble in organic solvents such as ether, acetone, and alcohols due to their similar nonpolar nature.
Where does isobutylene come from?
Isobutylene CAS 115-11-7 is commonly produced as a byproduct of the refining of crude oil and the processing of natural gas. It is often obtained through the catalytic dehydrogenation of isobutane, a process that involves removing hydrogen from isobutane to yield isobutylene. Isobutylene can also be obtained from other sources, such as the catalytic cracking of petroleum fractions or from steam cracking of hydrocarbons.
Additionally, isobutylene can be produced in petrochemical plants as part of the overall production of various chemicals and fuels. It is a versatile compound that serves as a starting material for the synthesis of numerous valuable products, including butyl rubber, high-octane gasoline additives, lubricants, refrigerants, and various chemical intermediates.
