  • Patent number: 10377728
    Abstract: A preparation method of an acidic and hydrophobic Pd/C catalytic material comprises performing a simple treatment with chlorosulfonic acid and trimethylchlorosilane, washing and drying a treatment product to obtain a modified Pd/C catalytic material. A method for preparing 2,5-methylfuran by catalyzing a carbohydrate with modified Pd/C comprises: dissolving the carbohydrate in alcohol, allowing a reaction to proceed with modified Pd/C as a catalyst and polymethylhydrosiloxane as a hydrogen donor at a temperature of 80˜140° C. for 1-5 hours, and performing centrifugation to separate the catalyst from the product. The content of the modified Pd/C content is 1-3 mol % relative to the carbohydrate; the polymethylhydrosiloxane amount is equivalent to 4-10 times the carbohydrate amount, and the carbohydrate concentration in the alcohol is 2-6 wt %.

The continuous vapor-phase processes are commercially viable and efficient because they permit the preparation of 2-methylfuran and 2-methyltetrahydrofuran using commercially-available catalysts, namely, a reduced copper-based catalyst consisting essentially of cupric oxide, chromium (III) oxide, manganese oxide and barium chromate and a reduced nickel-based catalyst consisting essentially of nickel, nickel (II) oxide, aluminum oxide and silica. An apparatus comprising two inline hydrogenators is used for preparing the 2-methylfuran or 2-methyltetrahydrofuran.

  • Patent number: 6916347
    Abstract: Primary intermediates for hair coloring compositions for oxidative dyeing of hair are compounds of the formula (1): where R1 and R2 are each individually selected from a hydrogen atom, a C1 to C3 alkyl group, a C1 to C5 mono or dihydroxyalkyl group, phenyl or benzyl optionally substituted with an alkoxy group, or R1 and R2 together with the nitrogen atom to which they are attached form a piperazine, piperidine, imidazole, or morpholine ring.

  • Publication number: 20040077872
    Abstract: The invention relates to a process for carrying out a homogeneously catalyzed C—C coupling reaction between an optionally substituted (hetero)aromatic bromide compound and a second reactant, which is chosen from the group of olefins in which at least one of the substituents on the olefinic sp2 carbon atoms is a hydrogen atom, and the group of organoboron compounds with the formula Ar—B(OR1)—OR2, where Ar stands for an optionally substituted (hetero)aryl group and R1 and R2 each independently represent H or an alkyl group or, together with the O-atoms to which they are bound and the B-atom, form a ring with 2-5 C-atoms, in the presence of an aprotic dipolar solvent and a base, a palladium salt without a ligand being used as palladium catalyst and the reaction being carried out at a ratio between the quantity of palladium present in the palladium salt and the optionally substituted (hetero)aromatic bromine compound of between 0.00001 and 0.1 mol %, preferably between 0.01 and 0.1 mol %.
