A refining process for chemically combining isobutane with olefin hydrocarbons (e.g., propylene, butylene) through the control of temperature and pressure in the presence of anacid catalyst, usually [..]

a chemical reaction in which propylene and butylenes are reacted with isobutylene resulting in isoheptane and isooctane (alkylates) with a high octane number.

Alkylation is one of the main reactions used in the petrochemical industry. It increases the number of carbon atoms in certain hydrocarbons found in fuel, boosting the octane rating to make the fuel m [..]

Illustrated Glossary of Organic Chemistry Alkylation (alkylate): A reaction in which an alkyl group is added to a molecule. Alkylation of a ketone enolate using LDA and a 1-iodopropane, a primary alky [..]

The covalent bonding of an alkyl group to an organic compound. It can occur by a simple addition reaction or by substitution of another functional group.

The covalent bonding of an alkyl group to an organic compound. It can occur by a simple addition reaction or by substitution of another functional group.

In refinery processing the introduction of an alkyl group into a molecule; sulphuric acid is a catalyst in alkylation.

a chemical term usually defined as the replacement of an available hydrogen atom within a chemical group such as the amino, carboxyl, or hydroxyl groups with an hydroxyethyl radical.

The substitution of an alkyl group for an active hydrogen atom in an organic compound. (12 Dec 1998)

A process using sulphuric or hydrofluoric acid as a catalyst to combine olefins and isoparaffins to produce a high octane product known as alkylate.

al-kuh-ley-shuhn Refining process for converting light, gaseous olefins into high-octane gasoline components (reverse of cracking).

A refining process used to produce improved gasoline components with, for instance, lower pollutant effects.

A refinery process for chemically combining isoparaffin with olefin hydrocarbons. The product, alkylate, has high octane value and is blended with motor and aviation gasoline to improve the antikn [..]

Refinery process used to produce high-octane gasoline blending stocks

Olefins such as propylene and butylene are produced by catalytic and thermal cracking. Alkylation refers to the process using sulfuric or hydro-fluoric acid as a catalyst to combine these olefins with isobutane to produce a high octane product known as alkylate.

(organic chemistry) Any reaction in which an alkyl group is added to a molecule; used in the production of high-octane petroleum fuels.
