    • A process for preparing a catalyst composition comprising copper oxide, zinc oxide and aluminum oxide as essential ingredients and optionally containing boron oxide, which comprises(a) a step of precipitating from an aqueous solution of a water-soluble copper salt optionally containing a water-soluble boron compound the copper component, together with the boron component if it is present, using an alkaline substance selected from alkali carbonates and alkali bicarbonates as a precipitant;(b) a step of blowing carbon dioxide gas into an aqueous dispersion of a zinc compound selected from zinc oxide and zinc hydroxide optionally containing a water-soluble boron compound to convert the zinc compound to basic zinc carbonate and simultaneously precipitate the boron component if it is present; and(c) a step of calcining a mixture of the solid products obtained in steps (a) and (b) in the presence of an alumina precursor compound.The resulting catalyst is useful for synthesizing methanol from a gaseous mixture of carbon monoxide and/or carbon dioxide and hydrogen.

    • 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.
