ABSTRACT:
A method of producing acrylamide from acrylonitrile in the presence of a metallic conversion catalyst which comprises contacting an oil-in-water emulsion of acrylonitrile, said water phase being the continuous phase and containing up to 7% acrylonitrile and said oil phase being the dispersed phase and containing the remaining acrylonitrile to be converted to acrylamide, whereby a substantial portion of the acrylonitrile is converted to acrylamide which remains in the aqueous phase of the oil-in-water emulsion, and then an additional low HLB emulsifier is added to invert the oil-in-water emulsion to a water-in-oil emulsion containing acrylamide.
