Process for preparing isocyanates and/or polycarbonates |
| abstract |
A method of preparing an isocyanate or polycarbonate comprising the steps of: providing a chlorine gas stream and a carbon monoxide stream; reacting the chlorine gas stream and the carbon monoxide stream to provide a phosgene stream; cooling the phosgene stream to the light the temperature at which the phosgene in the phosgene stream is liquid, preferably cooled to a temperature 4°C or more below the boiling point of phosgene to form a liquid phosgene stream and a gas stream; separating the gas stream and the liquid phosgene removing residual chlorine from the liquid phosgene stream to form a dechlorinated phosgene stream; and reacting the dechlorinated phosgene stream to form an isocyanate or polycarbonate. |
