Abstract:

A method has been developed for the solution-based metal exchange of carboxylato-alumoxanes [Al(O). sub. x (OH). sub. y (O. sub. 2 CR). sub. z ]. sub. n with a wide range of metal cations. Metal-exchanged carboxylato-alumoxanes are new, particularly those in which about 10% to about 50% or more of the Al ions are exchanged for other metal ions. Additionally, the carboxylic acid ligands can be stripped from the boehmite core of metal-exchanged carboxylato-alumoxanes at low temperature leading to the formation of metal-exchanged boebmite particles. These new material phases can be used as intermediates for preparation of mixed metal aluminum oxide materials. Thermolysis of the metal-exchanged carboxylato-alumoxanes or metal-exchanged boehmite particles results in doped aluminas (M/Al. sub. 2 O. sub. 3), binary (MAlO. sub. x), ternary (MM'AlO. sub.

Appl. No.:

6/699521

Abraham Morduchowitz - Monsey NY
Anthony F. Sammells - Naperville IL
Ronald L. Cook - Aurora IL

Assignee:

Texaco Inc. - White Plains NY

International Classification:

C25C 300

US Classification:

204 59R

Abstract:

Apparatus for the carbonylation of nitrobenzene or 2-5 dinitrotoluene with carbon dioxide to provide a product includes a housing which contains an electrolyte solution having a non-aqueous electrolyte containing a supporting electrolyte. A membrane divides the housing into two sections while permitting ions to move between the two sections. Carbon dioxide and nitrobenzene or 2-5 dinitrotoluene are provided to the housing. A d. c. voltage is provided across the electrolyte solution in the two sections of the housing, to cooperate in a reaction of the carbon dioxide, the nitrobenzene or the 2-5 dinitrotoluene and the electrolyte solution to provide a chemical product.

Assignee:

Texaco Inc. - White Plains NY

International Classification:

C25C 100

US Classification:

204 59R

Abstract:

A method and apparatus for providing two chemical products includes a reaction cell having an anode chamber and a cathode chamber. The anode chamber is separated from the cathode chamber by an ionic transfer membrane. Each chamber has an electrode connected to a source of DC voltage. A first electrolyte with a first sparging gas is provided to the anode chamber, while a second electrolyte with a second sparging gas is provided to the cathode chamber. The DC voltage, in cooperation with the electrolytes and the sparging gases causes products to form, one in each chamber. The first product is removed from the reacted electrolyte that emerges from the anode chamber while the second product is removed from the reacted electrolyte emerging from the cathode chamber.
