摘要： A process for the reaction of an organic compound in the presence of a catalyst comprising, as active metal, ruthenium alone or together with at least one Group Ib, VIIb, or VIIIb metal in an amount of from 0.01 to 30 wt %, based on the total weight of the catalyst, applied to a support, wherein from 10 to 50% of the pore volume of the support comprises macropores having a pore diameter in the range of from 50 nm to 10,000 nm and from 50 to 90% of the pore volume of the support comprises mesopores having a pore diameter in the range of from 2 to 50 nm, the sum of said pore volumes being 100%, and said catalyst as such.

摘要： A method for producing cyclohexanol by subjecting cyclohexene to a hydration reaction in the presence of water using a solid acid as a catalyst in which as a reaction solvent, there is used an organic solvent having a solubility in water at 25° C. of not higher than 5% by weight, a boiling point which is at least 20° C. higher than that of the cyclohexanol produced, a conversion rate of not more than 3% under the hydration reaction conditions, and a solvent effect index of not less than 1.5 which indicates the effect of making the distribution of cyclohexene into the aqueous phase predominate.
