    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an amine, comprising the reductive amination of the corresponding carbonyl or alcohol containing a considerable amount (at least 50 ppm, especially organically bound) of a halogen, by which the amine can simply be produced at a low cost in reduced catalyst consumption rate and in a high yield. SOLUTION: This method for producing the amine of formula (I): R R CH- NR R (I) (R , R , R and R are each, for example, a 1 to 12C alkyl), comprising the catalytic reductive amination of a mixture of a carbonyl compound of formula (II): R -C(=O)-R and/or an alcohol of formula (III): R -CH(OH)-R with at least 50 ppm (based on the mixture) of a halogen in the presence of a Co- and/or Ni-containing catalyst with a nitrogen compound of formula (IV): HNR R , is characterized in that the reductive animation is carried out in the additive presence of a solid acidic cocatalyst.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for synthesizing an anthraquinone, economically and simply in view of a production technology, not having a defect in a method publicly known by a preceding technology, starting from 1,4-naphthoquinone and 1,3-diene and capable of being executed in an industrial scale, especially capable of avoiding a risk of forming an explosive gas mixture in an oxidation process. SOLUTION: This method for producing an anthraquinone of general formula I (R to R are each same or different and hydrogen, an 1-8C alkyl, or 2-8C alkenyl), is provided by reacting 1,4-naphthquinone, with 1,3-diene of formula II (R to R are each same as described above) in a cyclizing addition process to form corresponding tetrahydroanthraquinone, and then reacting the tetrahydroanthraquinone with oxygen in the presence of a basic catalyst in an oxidation process to form the anthraquinone. The cyclizing addition process and the oxidation process are both performed in the presence of an aqueous diluent.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing the subject compound useful as an agricultural or pharmaceutical solvent or the like by which the compound is continuously produced in a high yield by reacting a specific urea derivative with a specific diketone, and hydrogenating the reaction product in the presence of a metal-containing catalyst. SOLUTION: A urea derivative of formula I (Y and Y' are each independently H, a linear or branched 1-4C alkyl, a 3-12C cycloalkyl or the like) is reacted with a diketone of formula II [X and X' are each independently H, hydroxy, a linear or branched 1-4C alkyl, a 3-12C cycloalkyl, a 1-4C alkoxy or the like; Z is a single bond, a 1-4C alkylene (substituted with a group X or X')], and the reaction product is hydrogenated in the presence of a metal-containing catalyst to provide the objective cyclic urea derivative of formula III in the method for producing the cyclic urea derivative. The reaction of the urea derivative with the diketone is preferably carried out in an aqueous solvent or an aqueous organism solvent, especially preferably carried out in the aqueous organic solvent containing 1-80 wt.% organic solvent based on the educt mixture.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a higher ketone in high selectivity and in a high yield. SOLUTION: This method for producing a higher ketone comprises reacting an aldehyde of general formula I [R1 is a substituted or nonsubstituted unsaturated 2-20C alkenyl group or a substituted or nonsubstituted 3-7C cycloalkenyl group] with a ketone of general formula II [R2 and R3 are each a substituted or nonsubstituted 1-20C alkyl or 2-20C alkenyl group or a substituted or nonsubstituted 3-1C cycloalkyl or cycloalkenyl group or R2 and R3 are bonded to form a substituted or nonsubstituted 3- to 7-membered carbon ring] in the presence of hydrogen and a catalytic system. The catalytic system is constituted of one or more kinds of components capable of transferring hydrogen to a double bond and a rare earth metal oxide, an alkaline earth metal oxide or their mixture.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an N-alkyl-N'-methylalkyleneurea, especially N,N'-dimethylpropyleneurea and N,N'-dimethylenthyleneurea without substantially containing formic acid. SOLUTION: This method for producing an N-alkyl-N'-methylalkyleneurea represented by the formula [R1 denotes H or CH3; R2 denotes CnH2n+1 (n is 1-4); and (x) denotes 0 or 1] without substantially containing formic acid comprises reacting the corresponding alkyleneurea with a monomeric formaldehyde or a polymerized formaldehyde in the presence of the formic acid. A mixture of the N-alkyl-N'-methylalkyleneurea with the formic acid obtained by the reaction is fed to an upper region of a distillation column and distilled without adding any substance to remove the N-alkyhl-N'-methylalkyleneurea without substantially containing the formic acid in a lower region of the distillation column. The pressure in the upper region of the distillation column at this time is set at a higher level than that in the lower region by 10-100 millibars and the temperature of the lower region of the distillation column is set at a higher level than that in the upper region by 40-210 deg.C.
