Abstract
Process for the preparation of an approximate mixture of the stereoisomeric equilibrium concentration of bis (4-aminocicloexil) methane, comprising the hydrogenation of bis (4-aminophenyl) methane or bis (4-aminocicloexil) methane, not at equilibrium concentration, a partial hydrogen pressure greater than 500 pounds per square inch (35.15 Kgs./om2) approximately and at a temperature of approximately 180 to 300º C, in the presence of a ruthenium and ammonia catalyst and, optionally, but preferably in the presence of a suitable solvent or diluent.
