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.
