Fester Katalysator für aliphatische Alkylierung

摘要

A catalyst comprises an organic or inorganic porous support impregnated by at least an active phase contg. an acid of formula R-SO3H where R is fluorine, an alkyl gp. or a fluoroalkyl gp. and at least a slight basic aprotic organic solvent. The catalyst formed consists of particles of mean dia. 0.1-150 mu m. The total pore vol. of the support before impregnation by the active phase is 0.5-6 cm<3>/g. Alkylation of at least an isoparaffin chosen from a gp. comprising of isobutane and isopentane in presence of an olefin contg. 3-6C /molecule using the above catalyst.
