Abstract
Aluminum alkyls are oxidized to aluminum alkoxides using a cobalt catalyst to increase the rate of oxidation. Alcohols can be prepared by hydrolysis of the aluminum alkoxides.
Claims16
A process for the oxidation of aluminum alkyls or partially oxidized aluminum alkyls, said process comprising, reacting said aluminum alkyls or partially oxidized aluminum alkyls with oxygen, air or other molecular oxygen containing gas mixture in the presence of a cobalt catalyst and a by-product suppressing catalyst selected from the group consisting of compounds of the Group 3, 4, 5 and 12 metals of the Periodic Table, so as to convert said aluminum alkyls or partially oxidized aluminum alkyls to aluminum alkoxides at an increased rate.
A process for the oxidation of aluminum alkyls, said process comprising the steps of:
- A. partially oxidizing said aluminum alkyls by reacting said aluminum alkyls with gas mixture, air or other molecular oxygen containing material, and
- B. further oxidizing the partially oxidized aluminum alkyls from step A by reacting said partially oxidized aluminum alkyls with oxygen, air or other molecular oxygen containing gas mixture in the presence of a cobalt catalyst whereby at least about 90% by weight of the aluminum alkyls are oxidized to their corresponding aluminum alkoxides.
A process for the information of alcohols by the oxidation and hydrolysis of aluminum alkyls said process comprising the steps of:
- A. partially oxidizing said aluminum alkyls by reacting said aluminum alkyls with oxygen, air or other molecular oxygen containing gas mixture,
- B. further oxidizing the partially oxidized aluminum alkyls from step A by reacting said partially oxidized aluminum alkyls with oxygen, air or other molecular oxygen containing gas mixture in the presence of a cobalt catalyst whereby at least about 90% by weight of the aluminum alkyls are oxidized to their corresponding aluminum alkoxides, and
- C. hydrolyzing said aluminum alkoxides to form said alcohols.
