    摘要： A carbocyclic or heterocyclic compound, ammonia and an oxygen-containing gas are subjected to fluid catalytic reaction in vapor phase in the presence of a catalyst containing alkali metal to produce an aromatic or heterocyclic nitrile. The use of the catalyst containing a specific amount of alkali metal enables the stable production of the aromatic or heterocyclic nitrile in high yields with little change with time even when water is present in the reaction system. The use of the catalyst containing the alkali metal also enables the recycle and reuse of unreacted ammonia which is usually accompanied by water, thereby reducing production costs.

    摘要： Disclosed is a process for producing methyl methacrylate which comprises:(I) a step of reacting prussic acid and acetone to form acetonecyanhydrin;(II) a step of hydrating the acetonecyanhydrin obtained in the step (I) to form .alpha.-hydroxyisobutyric acid amide;(III) a step of dehydrating the .alpha.-hydroxyisobutyric acid amide obtained in the step (II) to form methacrylic acid amide;(IV) a step of reacting the methacrylic acid amide obtained in the step (III) and methyl formate to form methyl methacrylate and formamide; and(V) a step of dehydrating formamide separated from the product obtained in the step (IV) to form prussic acid and recycling said prussic acid as a starting material in the step (I).The process produces methyl methacrylate with high selectivity without undesirable by-product such as ammonium sulfate.

    摘要： A di(aminomethyl)-substituted aromatic compound is produced by a two-stage hydrogenation. In the first stage, an aromatic dinitrile is hydrogenated into a cyano(aminomethyl)-substituted aromatic compound in the presence of a Pd-containing catalyst. The resultant cyano(aminomethyl)-substituted aromatic compound is then hydrogenated in the second stage into the target di(aminomethyl)-substituted aromatic compound in the presence of a Ni- and/or Co-containing catalyst. By the above method, the di(aminomethyl)-substituted aromatic compound is produced in a high selectivity and a sufficiently high yield without reducing the catalyst life.

    摘要： In a process for producing a polynitrile compound comprising introducing a polysubstituted organic compound (POC) which is a carbon ring or heterocyclic compounds having a plurality of organic substituents into a reactor with ammonia and a gas containing oxygen and ammoxidizing POC in the presence of a catalyst, at least a portion of the unreacted POC and a mononitrile compound of an intermediate product in the reaction gas discharged from the reactor is separated, recovered and recycled to the reactor so that the flow rate of the mononitrile compound at the outlet of the reactor is 2 to 16% by mole of the total flow rate of POC and the mononitrile compound supplied to the reactor.Burning reaction of the side reaction is suppressed and the loss of POC can be decreased without adverse effects on productivity and the polynitrile compound can be obtained at a high yield.
