Abstract
The invention provides an isoparaffin:olefin alkylation catalyst composition comprising at least one acid selected from the group consisting of hydrofluoric acid and the halogen-substituted sulfonic acids, together with a carbonate additive having the formula ROC(O)OR or ##STR1## wherein R is selected from alkyl, alkyl halide, aromatic and halogenated aromatic groups having from about 1 to about 30 carbon atoms, and an isoparaffin:olefin alkylation process employing the same.
Claims24
A process for alkylating an isoparaffin with an olefin comprising effecting reaction of isoparaffin and olefin with an alkylation catalyst composition comprising from about 10 to about 90 weight percent of at least one said selected from the group consisting of hydrofluoric acid and the halogen-substituted sulfonic acids, together with from about 10 to about 90 weight percent of an additive having the formula ROC(O)OR or ##STR10## wherein R is selected form alkyl, alkyl halide, aromatic and halogenated aromatic groups having from about 1 to about 30 carbon atoms.
A process for alkylating an isoparaffin with an olefin comprising effecting reaction of isoparaffin and olefin with an alkylation catalyst composition comprising from abut 10 to about 90 weight percent hydrofluoric acid and from about 10 to about 90 weight percent of an additive having the formula ROC(O)OR or ##STR13## wherein R is selected from alkyl, alkyl halide, aromatic and halogenated aromatic groups having from about 1 to about 30 carbon atoms, wherein said alkylation catalyst composition is a substantially nonfuming liquid at atmospheric temperature and pressure and wherein said process produces an alkylate product from a given feedstock having a ration of trimethylpentanes to dimethylhexanes of at least 65 percent of the ratio of trimethylpentanes to dimethylhexanes of the alkylate product produced by contacting said given feedstock with neat HF under like conversion conditions.
