Claims
- 1. A method of producing acrylamide from acrylonitrile in the presence of a metallic conversion catalyst which comprises contacting a water-in-oil emulsion of acrylonitrile which is contained in the dispersed aqueous phase of the emulsion under conditions whereby a substantial portion of the acrylonitrile is converted to acrylamide which remains in the aqueous phase of the emulsion.
- 2. The method of claim 1 where the conversion catalyst is a finely divided catalystically active species of copper.
- 3. The method of claim 2 where the finely dispersed conversion catalyst is a Raney copper catalyst which contains from about 2-45% by weight of aluminum.
- 4. The method of claim 1 where the conversion of acrylonitrile to acrylamide is done in the presence of sufficient sodium hydroxide to convert from 1-50% by weight of the nitrile and/or amide group to sodium acrylate groups.
- 5. The method of claim 1 where the metallic conversion catalyst is a homogeneous catalyst.
