Title:
PRODUCTION OF CYLOALKYLDIMETHANOL
Document Type and Number:
Japanese Patent JP3921877
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a cycloalkyldimethanol suppressible of elution of a catalyst component in a high yield by subjecting a cycloalkyldicarboxylic acid or the like to a hydrogenation reaction in a liquid phase using a catalyst such as ruthenium.
SOLUTION: This cycloalkyldimethanol (preferably 1,4-cyclohexanedimethanol) is obtained by subjecting at least one kind of raw material compound selected from a cycloalkyldicarboxylic acid (preferably 1,4-cyclohexanedicarboxylic acid) and its alkylated compound to a hydrogenation reaction using a catalyst containing at least catalyst components such as ruthenium, tin and platinum in an aqueous phase, preferably in the presence of a reaction solvent containing water, at 50-350°C under 0.1-30 MPa and in the presence of an alkali metal salt (preferably sodium sulfate, etc.), or an alkaline earth metal salt (preferably calcium hydroxide). The catalyst component is preferably a catalyst carried on a carrier (preferably carbonaceous).
