The invention relates to a process for producing isocyanates by reacting the corresponding amines with phosgene in the liquid phase, comprising: (a) mixing an amine comprising feed stream, a phosgene comprising feed stream and optionally an inert solvent; (b) reacting the amine with phosgene in a first reaction section to obtain an intermediate reaction mixture comprising isocyanate, carbamoyl chlorides, amine hydrochlorides and unreacted phosgene; (c) cleaving the carbamoyl chlorides and remove phosgene from the intermediate reaction mixture in a second reaction section to obtain an isocyanate comprising crude product, (d) optionally working-up the crude product; wherein reacting (b) is carried out such that the intermediate reaction mixture comprises 1.7 to 5 mol-% solid amine hydrochlorides based on the molar amount of amine fed into the process.

Process for producing isocyanates

The present invention relates to a process for preparing phosgene by reacting chlorine with carbon monoxide over an activated carbon catalyst, wherein the content of chlorine oxides in the chlorine feed stream is low, to an apparatus for preparation of phosgene and to the use of the phosgene prepared by the process of the invention.

Method for producing phosgene

The present invention relates to a phosphorus containing polyol, obtainable or obtained by a process comprising the reaction of at least one polyol with a phosphorus containing compound of the general formula (I) as defined herein, as well as the process for preparing a phosphorus containing polyol, comprising the reaction of at least one polyol with a phosphorus containing compound of the general formula (I). Furthermore, the present invention relates to the use of a phosphorus containing polyol as disclosed herein as a flame retardant, to a process for the preparation of a polyurethane and the polyurethane as such.
