MANUFACTURE OF POLYURETHANE BY CARBONYLATING HYDROXYAROMATIC NITRATED DERIVATIVE

Document Type and Number:

Japanese Patent JPS58206629

Kind Code:

A

Abstract:

A process for the manufacture of polyurethanes by direct reaction in the liquid phase, comprising reacting, in the presence of a catalyst, carbon monoxide with a nitrated hydroxy-aromatic derivative of the formula: HO-Ar-NO2 wherein Ar represents the aromatic radical: with the nitro and hydroxyl functional groups being in the para or meta positions with respect to each other, and R representing hydrogen or halogen atoms, or an alkyl group containing from 1 to 10 carbon atoms.
