#petroleum refining

• Alkylation — The act of alkylating and its result; a laboratory or industrial chemical process through which an alkyl radical is introduced into an organic molecule by replacing a hydrogen atom or another functional group. Alkylation is a fundamental reaction widely utilized in petroleum refining to obtain high-octane gasolines, as well as in drug and detergent synthesis.
• Alkylate — The liquid reaction product obtained in the petroleum refining industry through the alkylation process of isobutane with light alkenes (propene, butene); a mixture of branched saturated hydrocarbons with a high octane rating, utilized as a premium component for eco-friendly aviation and automotive gasolines due to its lack of aromatics or sulfur. As an adjective/participle, it describes an organic molecule into which an alkyl radical has been structurally introduced.
