    摘要： A reactor for producing a nitrile compound from a carbon ring or heterocyclic compound having organic substituents by a gas phase reaction using a fluidized catalyst bed with ammonia and a gas containing oxygen. In a cylindrical fluidized catalyst bed having a diameter of 2.0 meters or greater, partial vaporization-type cooling tubes (the cooling medium is partially vaporized in the tubes) and complete vaporization-type cooling tubes (the cooling medium is completely vaporized in the cooling tubes) are disposed in a specific arrangement. Water containing ionic SiO2 in 0.1 ppm or smaller and having an electric conductivity of 5 nullS/cm or smaller is used as the cooling medium for the complete vaporization-type cooling tubes. The temperature of the reaction is easily stabilized and uniform distribution of temperature is obtained in the fluidized catalyst bed. Stable continuous operation is achieved for a long time in a commercial scale apparatus.

    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.

    摘要： In a method for separating isophthalonitrile from a gas produced by causing m-xylene to react with ammonia and oxygen-containing gas in the presence of a catalyst, the gas is brought into contact with an organic solvent having a boiling point lower than that of isophthalonitrile; a liquid in which isophthalonitrile is trapped in a trapping step is distilled, to thereby recover isophthalonitrile and the organic solvent from the top of the column and separate at the bottom of the column impurities having boiling points higher than that of isophthalonitrile; and the organic solvent is recovered from the top of the rectification column and liquefied isophthalonitrile of high purity is recovered at the bottom of the column. Thus, loss of isophthalonitrile and plugging of a vacuum-evacuation system caused by isophthalonitrile migrating from a condensation system during distillation under reduced pressure can be prevented, and high-purity isophthalonitrile can be produced at high yield constantly for a long period of time.

    摘要： A carrier containing silicon carbide, inorganic bonding component, and at least one oxide selected from the group consisting of a niobium oxide, an antimony oxide, and a tungsten oxide carries at least one oxide selected from the group consisting of a vanadium oxide and a molybdenum oxide as catalytically active component. An inexpensive catalyst for catalytic oxidation use can be thus offered that does not change its properties over a period of time, that boasts stable catalytic activity over a period of time, and that is suitable for, e.g., manufacture of an acid anhydride and a nitrile compound by conducting a catalytic gas-phase oxidation reaction (partial oxidation reaction) on a hydrocarbon.

    摘要： A method for producing a purified phthalonitrile is described. The method involves reacting ammonia, oxygen, and xylene in the presence of a catalyst to obtain a product gas containing a phthalonitrile and a cyanobenzamide and then contacting the reaction product gas with an organic solvent to obtain a collection liquid. The collection liquid is distilled by a high boiling point fraction-separating column to obtain a gas that contains the phthalonitrile and the organic solvent from the column top, and to obtain a bottom liquid that contains a cyanobenzamide from the column bottom. The bottom liquid has a phthalonitrile content of 90% by mass or less. The bottom liquid is subjected to combustion, while being kept in a liquid state, and the purified phthalonitrile is obtained by removing the organic solvent from the gas that has been obtained from the column top.
