Abstract

PURPOSE: To catalytic reduction of 3,3'-dinitrodiphenyl sulfone is carried out in the coexistence of a specific alkali metal compound and a reduction catalyst containing Pd or Pt to produce the titled compound used as a starting material for producing high-molecular-weight compounds in high purity and yield.
CONSTITUTION: The catalytic reduction of 3,3'-dinitrodiphenyl sulfone with molecular hydrogen is carried out in a solvent such as 1W8C aliphatic alcohol or cyclohexanol in the presence of a catalyst containing Pd to produce the titled compound wherein at least one selected from hydroxides, oxides, carbonates and bicarbonates of alkali or alkaline earth metals is added to the reaction system to prevent the deactivation of the catalyst, resulting in high yield of the objective compound. The amount of the alkali metal compound employed is 0.1W5wt% on the basis of 3,3'- dinitrodiphenyl sulfone.
