MATERIAL BASED ON SILICON DIOXIDE, METHOD OF MATERIAL PRODUCTION, METHOD OF CATALYST PRODUCTION, METHOD OF ALKYLATION OF ALIPHATIC HYDROCARBON, METHOD OF CATALYST REGENERATION Russian patent published in 1999 - IPC

FIELD: alkylation of aliphatic hydrocarbons with olefins with catalyst material based on silicon dioxide. SUBSTANCE: method of alkylation of aliphatic hydrocarbons with olefins catalyzed with material based on silicon dioxide includes esterification of surface groups Si-OH of silicon-dioxide with fluoroalkylsulfonic acid of formula CF₃(CF₂)_nSO₃H, where n is integral number from 0 to 11. Catalyst material features Hammett acidity H_o≤ = 11.4. The catalyst offers not only high catalytic properties due to use of trifluoromethanesulfonic acid adsorbed on silicon dioxide but also possesses considerable stability in time and is easily regenerated. EFFECT: higher efficiency. 31 cl, 6 tbl
