    摘要: Apparatus and method for first mixing continuously at a prechosen flow rate a less dense fluid with a more dense fluid, the fluids being at least partially immiscible, so as to achieve a constant weight ratio of one fluid to the other per prechosen unit of mixed fluid volume transversely across the path of such mixed fluid followed by charging the resulting mixed fluid simultaneously to a multiplicity of tubes in a tubular reactor under conditions of substantially plug flow. At least one of the fluid is a liquid at all times.

    摘要: An improved process for making acrylamide from a composition of acrylonitrile and water utilizing an improved Raney copper catalyst. The catalyst is prepared by contacting particulate copper/aluminum alloy particles with an aqueous solution containing aliphatic hydrocarbon compound having at least two carbon atoms per molecule and further having at least two oxygen containing groups per molecule.
