Isobutane is the principal feedstock in alkylation units of refineries. Using isobutane, gasoline-grade "blendstocks" are generated with high branching for good combustion characteristics. Typical products created with isobutane are 2,4-dimethylpentane and especially 2,2,4-trimethylpentane. [7] Typical acid-catalyzed route to 2,4-dimethylpentane.
Isobutane, also known as methylpropane or 2-methylpropane Index of chemical compounds with the same molecular formula This set index page lists chemical structure articles associated with the same molecular formula .
Typical route for alkylation of benzene with ethylene and ZSM-5 as a heterogeneous catalyst. Alkylation is a chemical reaction that entails transfer of an alkyl group. The alkyl group may be transferred as an alkyl carbocation, a free radical, a carbanion, or a carbene (or their equivalents).
It is one of the most widely used hydroperoxides in a variety of oxidation processes, like the Halcon process. [3] It is normally supplied as a 69–70% aqueous solution. Compared to hydrogen peroxide and organic peracids, tert-butyl hydroperoxide is less reactive and more soluble in organic solvents. Overall, it is renowned for the convenient ...
The other general route to propylene oxide involves oxidation of propylene with an organic peroxide. The reaction follows this stoichiometry: CH 3 CH=CH 2 + RO 2 H → CH 3 CHCH 2 O + ROH. The process is practiced with four hydroperoxides: [10] In the Halcon process, t-Butyl hydroperoxide derived from oxygenation of isobutane, which affords t ...
It is a chlorinated derivative of isobutane. Synthesis. Isobutyl chloride can be synthesized in a substitution reaction by reacting isobutanol with hydrochloric ...
tert-Butyl alcohol is used as a solvent, ethanol denaturant, paint remover ingredient, and gasoline octane booster and oxygenate.It is a chemical intermediate used to produce methyl tert-butyl ether (MTBE) and ethyl tert-butyl ether (ETBE) by reaction with methanol and ethanol, respectively, and tert-butyl hydroperoxide (TBHP) by reaction with hydrogen peroxide.
