| titleOfInvention | METHOD FOR TEMPERING A GAS REACTION MIXTURE OBTAINED IN THE GAS PHASE PHOSGENATION OF DIAMINES |
| abstract | The present invention relates to a method of quenching, in a quench zone, a gaseous reaction mixture comprising a diisocyanate, phosgene and hydrogen chloride which is obtained in a reaction zone upstream of the phosgenation quench zone. of a gaseous phase diamine, the process comprising injecting a deposition prevention liquid into a deposition prevention zone located between the reaction zone and the quenching zone by passing the deposition prevention liquid through spray nozzles for the deposition prevention liquid at the inlet of the deposition prevention zone, each spray nozzle for the deposition prevention liquid spraying the deposition preventing liquid (i) on a wall segment of the deposition prevention zone which is adjacent to said spray nozzle for the deposition prevention liquid to produce a deposition prevention liquid film; flowing along the wall, and / or (ii) to areas in a cross-sectional plane of the deposition prevention zone prior to entering the quench zone. In another aspect, the present invention relates to a process for the preparation of a diisocyanate by phosgenation of a diamine (i.e. diamine corresponding to diisocyanate) in the gas phase, the quenching process as described in US Pat. the present invention being used for quenching, i.e. for partly cooling and condensing, the gaseous reaction mixture comprising a diisocyanate, phosgene and hydrogen chloride. |
