Abstract: ORGANIC CARBODIIMIDES ARE REACTED WITH CARBON MONOXIDE AND/OR CARBON DIOXIDE IN THE PRESENCE OF A CATALYST AT AN ELEVATED PRESSURE AND ELEVATED TEMPERATURE TO PRODUCE ORGANIC ISOCYANATES. THE CATALYST IS PREFERABLY AT LEAST ONE METAL OR COMPOUND OF A METAL FOUND IN GROUPS IB, IIB, IIIB, IVA, IVB, VIA,VIB,IIIA,VIIA,VIII, AND IN THE LANTHANIDE SERIES OF THE PERIODIC TABLE.

Abstract: IN THE PROCESS FOR PREPARING AN ORGANIC ISOCYANATE BY REACTING AN ORGANIC NITRO COMPOUND WITH CARBON MONOXIDE IN THE PRESENCE OF A CATALYST, IMPROVED YIELDS OF THE ORGANIC ISOCYANATE ARE OBTAINED AND CONTAMINATION OF THE ISOCYANATE BY PRODUCTS DERIVED FROM ORTHO-DINITRO COMPOUNDS IS SUPRESSED WHEN THE REACTION IS CARRIED OUT IN THE PRESENCE OF AN ORGANIC CARBONATE. IN ADDITION, WHEN THE CATALYST IS A NOBLE METAL HALIDE COMPLEX OF LEWIS BASE SUCH AS PYRIDINE OR ISOQUINOLINE, DECOMPOSITION OF THE CATALYST COMPLEX IS DIMINISHED.

Abstract: MONOCARBODIIMIDES AND ORGANIC ISOCYANATE-MONOCARBODIIMIDE ADDUCTS ARE PROVIDED BY HEATING ORGANIC ISOCYANATES IN THE PRESENCE OF A CATALYTIC AMOUNT OF PHENYLPHOSPHONIC DIAMIDE AT A TEMPERATUREA FROM ABOUT 120* TO ABOUT 190*C. THE MONOCARBODIIMIDES ARE USEFUL AS CATALYSTS AND CHEMICAL INTERMEDIATES; THE ADDUCTS ARE USEFUL IN THE PREPARATION OF POLYURETHANE FOAMS.
