An improved catalyst based on cobalt and/or rhodium dissolved in a non-aqueous ionic solvent which is liquid at a temperature of less than 90&deg; C. More particularly, the catalyst comprises at least one complex of cobalt and/or rhodium co-ordinated with at least one nitrogen-containing ligand and the non-aqueous ionic solvent comprises at least one quaternary ammonium and/or phosphonium cation and at least one inorganic anion.

Catalyst based on cobalt and/or rhodium employed in a two-phase medium

The invention concerns a catalytic composition resulting from a mixture of at least one aluminium halide, at least one quaternary ammonium halide and/or at least one amine hydrohalide and at least one group IVB metal compound, preferably a group IVB metal halide. The invention also concerns a process for alkylating isoparaffins by olefins using that composition, the olefin preferably being a low reactivity olefin.

Catalytic composition and aliphatic hydrocarbon alkylation process

Improved process for implementing the Diels-Alder reaction that consists in using reagents in the presence of at least one liquid salt of general formula Q.sup.+ A.sup.-, in which Q.sup.+ represents a quaternary ammonium and/or phosphonium and A.sup.- represents an anion and optionally at least one Lewis acid. The anion is preferably selected from the group that is formed by tetrafluoroborate, hexafluorophosphate, hexafluoroantimonate, hexafluoroarsenate, perfluoroalkylsulfonate, fluorosulfonate or else dichlorocuprate, tetrachloroborate, tetrachloroaluminate, and trichlorozincate. At the end of the reaction, the organic phase is separated, and the polar phase is reused.

Process for dienoic condensation known as the diels-alder reaction

The invention concerns a catalytic composition resulting from mixing at least one aluminum halide, at least one quaternary ammonium halide and/or at least one amine halohydrate and at least one cuprous compound, preferable a halide. The invention also concerns a process for the alkylation of isoparaffins by olefins with that composition.

Catalytic composition and process for the alkylation of aliphatic

A catalyst containing a porous organic or mineral support and at least one active phase having at least one aluminum halide, at least one compound selected for quaternary ammonium halides and amine hydrohalides, and at least one cuprous compound, the support having been impregnated with the active phase, the catalyst essentially constituted by particles with an average diameter in the range 0.1 .mu.m to 150 .mu.m, and the support, before impregnation with the active phase, has a total pore volume in the range 0.1 cm.sup.3 /g and 6 cm.sup.3 /g.

Aliphatic alkylation catalyst comprising an active phase containing a

A non-aqueous liquid composition with an ionic character resulting from the contacting of at least one alkylaluminum dihalide with at least one quaternary ammonium halide and/or at least one quaternary phosphonium halide, said composition being liquid below 80.degree. C., for example, between -70.degree. and +40.degree. C., is useful as a solvent of catalysts for the dimerization, codimerization and oligomerization of olefins.

Non-aqueous liquid composition with an ionic character and its use as a

N-acyliminodiacetic acids are manufactured by reacting formaldehyde or a formaldehyde generator compound with a N-unsubstituted amide or a generator thereof and with carbon monoxide in contact with a carbonylation catalyst, for example, a cobalt compound, the ratio of the aldehyde groups to the amide groups being at least 2:1. The formaldehyde generator can be a polymeric form of formaldehyde and the amide generator can be a carboxylic ester, acid or anhydride.

Process for manufacturing N-acyliminodiacetic acids

A N-acyl .alpha.-amino acid is manufactured by reacting an unsaturated vegetable oil or a C.sub.8 -C.sub.30 mono-olefinic compound with an amide, carbon monoxide and hydrogen, in the presence of a cobalt catalyst. The process is operated in one step, providing for an increased selectivity as compared with a two-step process.

Process for manufacturing a N-acyl .alpha.-amino acid

Highly unsaturated oils of vegetable or animal origin are selectively hydenated to less highly unsaturated oils using a catalytic composition obtained by dissolving a compound of a metal selected from the IB, IV B to VII B or VIII groups in an unsaturated oil and then adding thereto an organic derivative or hydride of a metal from groups I A, II A, II B or III A, in the absence of a stabilizing solvent.
