    Abstract: IMPROVEMENTS IN REACTIONS FOR PRODUCING ORGANO ALUMINUM COMPOUNDS ARE DESCRIBED. THE IMPROVEMENTS INVOLVE HALIDES OF ALKALI METALS AS CATALYSTS OR ACTIVATORS FOR REACTIONS INVOLVING ALUMINUM WITH AN ORGANO ALUMINUM COMPOUND AND HYDROGEN OR WITH OLEFIN AND HYDROGEN IN THE PRESENCE OF AN ORGANO ALUMINUM COMPOUND. PREFERRED CATALYTIC HALIDES ARE THE FLUORIDES. A PREFERRED ALKALI METAL CONSTITUENT OF THE CATALYST COMPOUNDS IS SODIUM; HOWEVER, CERTAIN OTHER COMPOUNDS WHICH ARE OTHER COMBINATIONS OF OTHER HALOGENS, INCLUDING PSUEDO HALOGENS, WITH OTHER ALKALI METALS ARE ALSO DISCLOSED AS USEFUL CATALYSTS. THE PREFERRED COMPOUNDS ARE SIMILAR TO THE ALKALI METALS IN EFFECTIVENESS AND ARE MUCH EASIER TO HANDLE AND USE.

    Abstract: A method of manufacturing alkylaluminum compounds from ternary or quaternary alloys, comprising as principal elements aluminum, silicon and titanium, and aluminum, silicon, titanium and iron, respectively, wherein said alloys are reacted with hydrogen and an aluminum alkyl. An olefin and/or a catalyst may also be added in the reaction.

    CPC classification number: C03C17/10

    Abstract: A PROCESS FOR APPLYING AN ALUNINUM PLATE ON A WIDE VARIETY OF MATERIALS TO PRODUCE ARTICLES HAVING DESIRABLE QUALITIES EXEMPLIFIED BY GOOD CORROSION RESISTANCE. A FIRST EMBODIMENT OF THE INVENTION IS CHARACTERIZED BY CONTACTING THE SUBSTRATE TO BE COATED WITH A SOLUTION CONTAINING A SUITABLE CATALYST AND A TRIBYDROCARBYLAMINE COMPLEX OF ALUMINUM HYDRIDE AT RELATIVELY LOW TEMPERATURES, I.E., BELOW 150*C. DECOMPOSITION OF THE COMPLEX IS EFFECTED BY CATALYSTS AND ALUMINUM PLATING OCCURS ON THE EXPOSED SURFACES OF THE SUBSTRATE. IN A SECOND PROCESS EMBODIMENT THE SUBSTRATE IS COATED WITH A CATALYST AND SUBSEQUENTLY BROUGHT INTO CONTACT WITH A SOLVENT CONTAINING A DISSOLVED ALUMINUM HYDRIDE-TRIHYDROCARBLAMINE COMPLEX TO EFFECT THE DESIRED ALUMINUM DEPOSITION. THE PROCESS OF THIS INVENTION PROVIDES A HIGHLY USEFUL AND NOVEL METHOD OF PLATING SUBSTANTIALLY ANY MATERIAL WITH A UNIFORM, STRONGLY ADHERENT ALUMINUM COATING OF DESIRED THICKNESS.

    IPC: C01B6/24

    CPC classification number: C01B6/243

    Abstract: A process for preparing alkali metal aluminum hydride comprising reacting together an alkali metal, or the hydride thereof, with aluminum having alloyed therewith either Ti or Zr, under hydrogen pressure in the presence of a tertiary amine. Preferably, the catalyst comprises a tertiary amine and a hydrocarbon compound which is capable of being metallized under the reaction conditions, such as triphenylmethane, indene, thiophene, fluorene, and alpha-picoline. Reaction times are reduced to about one-third normal and provides for recycling the catalysts and reaction media in which the reaction is conducted. Sodium aluminum hydride prepared by this method is a good source of high-purity hydrogen for use in fuel cells and the like. Reaction temperatures range from 50* C. to 200* C. under pressures of from 500 to 10,000 pounds per square in (p.s.i.).

    Abstract: ALUMINUM IS PRODUCED BY THERMOCATALYTIC DISPROPORTIONATION OF DIALKYLALUMINUM HYDRIDE INTO ALUMINUM, TRIALKYLALUMINUM AND HYDROGEN. THE AMOUNT OF OLEFIN LIBERATED, IF ANY, IS VERY SMALL. UNITARY OPERATIONS USING THE DISPROPORTIONATION REACTION FOR CONVERING CRUDE ALUMINUM INTO PURIFIED ALUMINUM ARE DESCRIBED. ONE SUCH OPERATION INVOLVES THE FOLLOWING: CRUDE AL + 2R3AL + 3/2 H2--> 3R2ALH + SOLIDS WHICH REDUCES TO CRUDE AL + CATALYST --> PURIFIED AL + SOLIDS 3R2ALH + CATALYST--> PURIFIED AL + 2R3AL + 3/2 H2
