SILICON DIOXIDE-BASED MATERIAL, PROCESS FOR PREPARING CATALYST, PROCESS FOR ALKYLATING ALIPHATIC HYDROCARBON, AND PROCESS FOR REGENERATING CATALYST

摘要

FIELD: chemical industry. SUBSTANCE: process for alkylating aliphatic hydrocarbons with olefins catalyzed by silicon dioxide- based material is characterized in that surface groups Si-OH of silicon dioxide are esterified with fluoroalkylsulfonic acid of formula: CF(CF)SOH, wherein n is integer of 0 to 11, said material having Hammet acidity of equal or greater than -11.4. EFFECT: improved properties of the title material and more efficient preparation process.
