Abstract:
A process for manufacturing isocyanates or polycarbonates comprising the steps of: providing a chlorine stream and carbon monoxide stream; reacting said chlorine stream and said carbon monoxide stream for providing a phosgene stream; cooling the phosgene stream to a temperature at which the phosgene in the phosgene stream is liquid, preferably, to a temperature that is 4° C. less or more than 4° C. less than the boiling point of phosgene, to form a liquid phosgene stream and a gas stream; separating the gas stream and the liquid phosgene stream; removing residual chlorine from the liquid phosgene stream to form a chlorine depleted phosgene stream and reacting the chlorine depleted phosgene stream to form an isocyanate or a polycarbonate.

Claim (Index 1):
A process for manufacturing isocyanates comprising the steps of:\n a) providing a chlorine stream and carbon monoxide stream, wherein the chlorine stream comprises less than 500 ppm bromine; b) reacting said chlorine stream and said carbon monoxide stream for providing a phosgene stream, wherein the mole ratio carbon monoxide in the carbon monoxide stream over chlorine in the chlorine stream is in a range of between 0.900:1.000 to 1.025:1000; c) cooling the phosgene stream to a temperature at which the phosgene in the phosgene stream is liquid, to form a liquid phosgene stream and a gas stream; d) separating the gas stream and the liquid phosgene stream; e) removing residual chlorine from the liquid phosgene stream to form a chlorine depleted phosgene stream; g1) reacting the chlorine depleted phosgene stream with an amine compound to form a corresponding isocyanate compound.
