Task: Translation
Input (Spanish): A process for the alkylation of aliphatic hydrocarbons with olefins catalyzed by a silica-based material, characterised in that the surface Si-OH groups of said silica are esterified with a fluoroalkylsulphonic acid of formula CF3(CF2)nSO3H, where n is a whole number between 0 and 11, said material having a Hammett acidity Ho</=-11.4.
Output (English): Un procedimiento para alquilacion de hidrocarburos alifaticos con olefinas catalizas con un material a base de silica, caracterizado porque los grupos superficiales Si-OH de esa silica se esterifican con acido fluoroalquilsulfonico de la formula CF3(F2)nSO3H, en donde n es un numero entero entre 0 y 11, el material tiene un acidez Hammett Ho-11.4.
