Abstract
A composition of matter comprises trifluorometbanesulfonic acid and a solid inorganic material which contains aluminum borate and aluminum oxide, This composition is used as a catalyst for alkylating at least one C.sub.2 -C.sub.10 alkane (preferably isobutane and/or an isooctane) with at least one C.sub.2 -C.sub.10 alkene (preferably pentene-1 and/or hexene-1).
Claims20
A process for alkylating alkanes which comprises contacting at least one feed alkane containing about 4-8 carbon atoms per molecule with at least one feed alkene containing about 4-6 carbon atoms per molecule in the presence of a catalyst composition which consists essentially of (a) trifluoromethanesulfonic acid and (b) a solid inorganic material consisting essentially of aluminum borate and aluminum oxide, at effective alkylation conditions comprising a reaction temperature of up to about 100.degree. C., so as to obtain a product in which the weight percentage of product alkanes boiling in a temperature range of about 310.degree. F. to about 500.degree. F. at atmospheric pressure conditions exceeds the weight percentage of product hydrocarbons boiling at a temperature above 500.degree. F. at atmospheric pressure conditions.
A process for producing alkanes boiling in a temperature range of about 310.degree. F. to about 500.degree. F. at atmospheric pressure conditions which comprises contacting at least one feed alkane containing about 4-8 carbon atoms per molecule with at least one feed alkene containing about 4-6 carbon atoms per molecule in the presence of a catalyst composition which consists essentially of (a) trifluoromethanesulfonic acid and (b) a solid inorganic material consisting essentially of about 5-15 weight-% aluminum borate and aluminum oxide as the remainder, at effective alkylation conditions comprising a reaction temperature of about -20.degree. C. to about 100.degree. C., so as to obtain at least one product alkane boiling at a temperature of about 310.degree.-500.degree. F. at atmospheric pressure conditions.
