  • Process for producing a cyclic aliphatic oxime
    Patent number: 6930204
    Abstract: Disclosed is a method for producing a cyclic aliphatic oxime, which comprises subjecting a cyclic aliphatic primary amine to oxidation in the liquid phase under superatmospheric pressure in the presence of molecular oxygen and a solid catalyst, wherein the solid catalyst comprises an oxide of at least one metal (a) selected from the group consisting of metals belonging to Groups 5 and 6 of the Periodic Table.
    Type: Grant

  • Method for reactivating ruthenium catalyst
    Patent number: 6077983
    Abstract: A method for recovering the activity of a ruthenium catalyst which comprises a step of bringing a ruthenium catalyst decreased in activity by its use in hydrogenation of an unsaturated organic compound into contact with oxygen in a liquid phase, and a step of maintaining the catalyst at a hydrogen partial pressure lower than that at the hydrogenation and a temperature not lower than a temperature lower by 50.degree. C. than the hydrogenation temperature.

  • Production method of 2-cyclohexene-1-ol
    Patent number: 5900513
    Abstract: The present invention provide a method for producing 2-cyclohexene-1-ol which comprises using a catalyst containing an inetermetallic compound of palladium and lead and/or bismuth when cyclohexenyl hydroperoxide is subjected to hydrogenolysis to produce 2-cyclohexene-1-ol.If the catalyst of the present invention is employed, it is possible to obtain the desired 2-cyclohexene-1-ol at a high selectivity with a much simpler reaction system than the prior art and, in addition, to inhibit the hydrogenation of coexisting cyclohexene sufficiently.
