Although virtually every known solid acid has been screened for its alkylation activity, solid-acid catalyzed isobutane alkylation is not commercially practiced today as the solid-acid catalysts deactivate rapidly as a result of coke buildup.
When acid catalysts are used, there must be a tertiary carbon atom in the alkane that is to react with the olefin, such as in isobutane and isopentane. The mechanism goes through a carbonium ion, which needs to be in the tertiary form in order to “spread out” the charge. The use ...

Isobutane Concentration In the alkylation reaction, a molecule of olefin reacts with a molecule of isobutane to form an alkylate molecule. This reaction occurs in the presence of a sulfuric acid catalyst. A side reaction that competes with the alkylation reaction is polymerization. In this reaction...

Liquid carbon dioxide was studied as a solvent for the isobutane–isobutylene alkylation. The acid catalysts in the reaction were anhydrous HF (AHF), pyridinium–poly(hydrogen fluoride) complex (PPHF), concentrated sulfuric acid and trifluoromethanesulfonic acid (TFSA). The effect of the acid–hyd...
