Alkylation 4
Alkylation 4 : Chemistry and Chemical Disasters. Any process whereby an alkyl group is added to another molecule; however, in process chemistry the word is most commonly used to designate a reaction in which an olefin is added to a saturated aliphatic hydrocarbon or an aromatic compound. In the petroleum and petrochemical industries, this term refers to the conversion of a mixture of light olefins and isobutane into a mixture of alkanes suitable for blending into gasoline in order to increase the octane number. An acid catalyst is used. Originally the acid chosen was anhydrous hydrofluoric or sulfuric acid
