A process for the conversion of linear and/or branched paraffin hydrocarbons based on the use of an ionic liquid catalyst in combination with a metal salt additive, which provides a catalytic composition with an increased activity, compared with said ionic liquid. Under suitable reaction conditions this conversion is leading to paraffin hydrocarbon fraction with higher octane number.

Process for paraffin hydrocarbon isomerization and composite catalyst therefore

A process for the conversion of linear and/or branched paraffins hydrocarbons, catalysed by an ionic liquid catalyst, in the presence of a cyclic hydrocarbon additive containing a tertiary carbon atom. The presence of the specific hydrocarbon additives influences the reaction mechanism by increasing the selectivity towards the formation of paraffin hydrocarbons with a higher degree of branching.

Process of paraffin hydrocarbon isomerisation catalysed by an ionic liquid in the presence of a cyclic hydrocarbon additive

A method for hydrolysis of a sulphonic acid ester in a hydrocarbon substrate by aqueous extraction of the hydrocarbon substrate, comprising steps of contacting the hydrocarbon substrate with an aqueous phase containing an ammonia salt, thereby hydrolyzing the sulphonic acid ester to the corresponding sulphonic acid; and recovering the sulphonic acid by separating the aqueous phase from the hydrocarbon substrate.

Recovery of sulphonic acid esters from a hydrocarbon stream

Preparation of fluorinated alkyl sulphonyl halides having the general formula: ##STR1## where R.sup.I.sub.f is fluorinated alkyl group and R.sup.II.sub.f is a fluorinated alkyl group or fluorine, X is a halogen atom, and Y is a proton, a halogen atom, or a fluorinated alkyl groups, by reaction of a corresponding fluorinated unsaturated hydrocarbon with sulphuryl halide, wherein the reaction is carried out in the presence of at least catalytic amounts of a fluoride in a solvent comprising compounds having one or more SO and/or SO.sub.2 groups incorporated in the compound structure.

Process for the synthesis of fluorinated alkyl sulphonyl halides

Process for the preparation of a fluorinated sulphonic acid compound by hydrolysis of a corresponding fluorinated sulphonyl fluoride in the presence of a tertiary amine, comprising steps of

Process for the synthesis of fluorinated sulfonic acids

Process for the preparation of a fluorinated sulphonic acid compound by hydrolysis of a corresponding fluorinated sulphonyl fluoride, wherein the hydrolysis is carried out in the presence of a tertiary amine, comprising steps of recovering a mixture of a salt of hydrolysed fluorinated sulphonyl fluoride with the tertiary amine and an ammonium fluoride salt of the tertiary amine;
