Abstract
PURPOSE: To prepare the title compounds useful as a raw material of dyes, pharmaceuticals, pesticides, synthetic resins, etc., by reducing nitrodiphenyl ethers with hydrogen in the presence a hydrogenation catalyst, using glycol monoether monoesters as a solvent.
CONSTITUTION: The objective compound III (Y1W4 are H, alkyl, amino, halogen; n, m are 1 or 2; Z is H, amino), e.g. 4,4'-diaminodiphenyl ether, is prepared by reducing a nitrodiphenyl ether I (X is H, nitro), e.g. 4,4'-dinitrodiphenyl ether, with hydrogen, in the presence of a hydrogenation catalyst (e.g. Pd/C) using mono- or poly-alkylene glycol monoether monoester II (R1,3 are alkyl; R2 is alkylene; n is 1W3), e.g. 2-ethoxyethyl acetate, as solvent.
EFFECT: The produced water can be easily removed from the reaction system by, e.g. liquid separation.
