Abstract
In reduction of an epoxy group-containing organic compound, for example, a C5-C20 saturated or unsaturated epoxy cycloaliphatic compound, in the presence of a nickel catalyst, by bringing the compound into contact with hydrogen, the target compound can be produced at a high yield by adding a basic substance (for example, an alkali metal hydroxide, an alkali metal carbonate, an alkali metal alkoxide, and an amine compound having 1 to 3 C1-C12 alkyl groups), to the reduction reaction system, to thereby restrict production of by-products due to a side deoxidation reaction.
Claims11
A method of reducing an epoxy group-containing organic compound with hydrogen, comprising
- contacting a nickel catalyst and a basic substance to form a basic substance-carrying nickel catalyst,
- pretreating the basic substance-carrying nickel catalyst with hydrogen, and
- bringing an epoxy group-containing saturated or unsaturated cycloaliphatic organic compound having 5 to 20 carbon atoms into contact with hydrogen in the presence of the basic substance-carrying nickel catalyst, to reduce the epoxy group-containing saturated or unsaturated cycloaliphatic organic compound in a hydrogen reduction reaction system.
