Abstract:
The present invention provides a process for the conversion of a reactant into a reaction product in the presence of a solid acid catalyst comprising one or more fluorine atoms, sulfo radicals and phosphono radicals, each such radical being bonded to the same or different carbon atom, with the proviso that at least one sulfo radical and at least one phosphono radical are bonded to such carbon atoms through the sulfur atom and the phosphorus atom, respectively. These compounds are preferably non-polymeric, i.e. they have a molecular weight of about 5000 or less. The above acid catalysts may be reacted with a tetravalent metal, e.g. Zr, to provide a solid acid catalyst.
Abstract:
This invention is directed to a catalyst system for use in the alkylation of isoparaffin with olefins. More specifically, this invention is directed to an improved catalyst system containing specified amounts of water and a component of that system comprising certain transition aluminas promoted with a Lewis acid (preferably BF3). In addition, this invention is a catalytic process for the alkylation of isoparaffin with olefins. The catalyst component is produced by contacting the transition alumina with the Lewis acid at relatively low temperatures. The catalyst system comprises that component and an additional amount of free Lewis acid. The process entails isoparaffin alkylation with olefins using the catalyst component and its allied catalyst system.
Abstract:
This invention is a process for the production of trialkyl acetic acids, particularly of pivalic acid, from branched olefins, particularly isobutene, and carbon monoxide using catalytic amounts of a Lewis acid such as boron trifluoride.
Abstract:
The present invention provides an acid catalyst complex comprising an organosulfonic acid having at least one covalent carbon-fluorine bond or one covalent carbon-phosphorus bond provided by a phosphono radical which has been contacted with a Lewis Acid to produce a catalyst complex containing said Lewis Acid. The present invention also provides a process for the conversion of a reactant into a reaction product in the presence of said catalyst complex. In particular, the catalyst complex is useful for providing a high octane alkylate stream by converting a mixture comprising isoparaffins and olefins into said alkylate in the presence of said catalyst complex.

Abstract:
Cette invention concerne a) un système de catalyseur, b) un composant de ce système comprenant certaines alumines de transition améliorées par un acide de Lewis (de préférence BF3), et c) un procédé catalytique pour l'alkylation d'isoparaffine avec des oléfines. Le composant catalyseur est produit en mettant en contact l'alumine de transition avec l'acide de Lewis à des températures relativement basses ou à des températures auxquelles certaines caractéristiques apparaissent dans le spectre de résonance magnétique nucléaire (RMN) du composant. Le système de catalyseur comprend ce composant et une quantité additionnelle d'acide de Lewis libre. Le procédé permet l'alkylation d'isoparaffine/oléfine en utilisant le composant catalyseur et le système catalytique associé.

The catalyst component is produced by contacting the transition alumina with the Lewis acid at relatively low temperatures or at those temperatures at which certain characteristic peaks appear in the component's nuclear magnetic resonance (NMR) spectrum.

Abstract:
L'invention concerne un procédé de conversion d'un réactif en un produit de réaction en présence d'un catalyseur acide solide comprenant un ou plusieurs atomes de fluor, des radicaux sulfo et des radicaux phosphono, chacun desdits radicaux étant lié au même atome de carbone ou à un atome de carbone différent, à condition qu'au moins un radical sulfo et au moins un radical phosphono soient liés auxdits atomes de carbone par l'atome de soufre et l'atome de phosphono respectivement. Ces composés sont de préférence non polymères, c'est-à-dire qu'ils ont une masse moléculaire d'environ 5000 au moins. On peut faire réagir les catalyseurs acides précités avec un métal tétravalent, par exemple Zr, afin de produire un catalyseur acide solide.
