Abstract

A method includes organic homologation employing an organic-containing feed. The organic-containing feed is directed into a molten metal bath. The molten metal bath includes a metal which can cause an organic component of the organic-containing feed to homologate and form a homologated organic compound. Operating conditions are established and maintained in the reactor to cause the organic component to form a homologated organic compound that is discharged from the molten metal bath.

a) providing a reactor containing a molten metal bath, said molten metal bath including a metal which can cause an organic component of the feed to form a homologated organic compound;

b) directing the organic-containing feed into the molten metal bath at a rate which causes the carbon content of the molten bath to be at about the saturation limit of the molten metal bath; and

c) establishing and maintaining operating conditions in said reactor to cause the organic component of the feed to homologate and form said homologated organic compound that is discharged from the molten metal bath.

2. A method of claim 1 wherein the metal provided includes a transition metal.

3. A method of claim 2 wherein the reactor which is provided contains a molten metal bath including a transition metal that has an energy gap between its ground and first excited electronic states that is less than about 1.5 eV.
