The liquid-phase hydration of acrylonitrile to acrylamide has been examined over various metal catalysts at 75 deg C.Five metal elements - Cu, Ag, Fe, Co, and Ni - showed the catalytic conversion of acrylonitrile.The Cu and Ag catalysts gave the acrylamide with a 100 percent selectivity, while the other metals, Fe, Co, and Ni, yielded three products: acrylamide, ehylene cyanohydrin, and bis(2-cyanoethyl) ether.The alloying of Cu and Ni led to an increse in the formation of acrylamide with keeping the high selectivity to acrylamide.Especially, Cu-Ni alloys, with a range of 20-70 percent Cu in their bulk composition, were much more active catalysts than Cu.The maximum yield of acrylamide was obtained on the Cu-Ni alloy catalysts was observed, although such a retardation occurred on the Cu catalyst surface.The maximum synergistic effect was observed over the alloy with the surface component ratio of Cu to Ni of 4; this effect was discussed.

The selective hydration of acrylonitrile to form acrylamide has been studied on several metal oxide catalysts.MnO2, CuO and Co3O4 catalysts were found to be active and selective.Catalytic activities were strongly affected by the method of preparation.Hydration activity of MnO2 was related to the amount of phenol adsorption.

The invention relates to a preparation method of 3-aminopropanol, wherein the preparation method comprises the following steps: (1) carrying out a reaction on acrylonitrile with benzyl alcohol under the catalysis of a base catalyst, and separating the obtained reaction solution to obtain 3-benzyloxypropionitrile; and (2) in a liquid-phase reaction system in the presence of a hydrogenation catalyst, carrying out a hydrogenation reaction on the 3-benzyloxypropionitrile, separating the obtained reaction liquid to obtain 3-aminopropanol, and recycling the obtained by-product toluene as an extractant in the step (1).

Paragraph 0030; 0031; 0032; 0033; 0034; 0035; 0036-0048, (2017/07/20)
The invention relates to a method for catalytically synthesizing 3-hydroxylpropionitrile from hydrocyanic acid and epoxyethane. An activated alumina immobilized boron trifluoride and 1,2-pentanediol complex is used for catalyzing a reaction between hydrocyanic acid and epoxyethane so as to synthesize 3-hydroxylpropionitrile. By the method, during the reaction, a reaction mixture is not required to be neutralized with a large volume of acid, and the generation of a large amount of inorganic salts is absent, so that the reaction has the atom economy of 100%; the reaction route is short, the number of operating steps is small, and the product separation is easy, so that the reaction is simple and convenient in operation; and hydrocyanic acid in a system is free of risk of numerous overflowing under the condition of low-temperature reaction, so that the reaction is safe in operation.

The oxidative decarboxylation of amino acids to nitriles was achieved in aqueous solution by in situ halide oxidation using catalytic amounts of tungstate exchanged on a [Ni,Al] layered double hydroxide (LDH), NH4Br, and H2O2 as the terminal oxidant. Both halide oxidation and oxidative decarboxylation were facilitated by proximity effects between the reactants and the LDH catalyst. A wide range of amino acids was converted with high yields, often > 90%. The nitrile selectivity was excellent, and the system is compatible with amide, alcohol, and in particular carboxylic acid, amine, and guanidine functional groups after appropriate neutralization. This heterogeneous catalytic system was applied successfully to convert a pro-tein-rich byproduct from the starch industry into useful biobased N-containing chemicals.
