METHOD FOR MANUFACTURING ISOCYANATES IN THE GASEOUS PHASE

Producing primary isocyanates comprises feeding at least one feed stream containing phosgene (P) and at least one feed stream containing primary amines (A) to the reaction chamber through a nozzle assembly, where the amines are reacted above its boiling point with phosgene. The nozzle arrangement ha...

Beschreibung
Zusammenfassung:	Producing primary isocyanates comprises feeding at least one feed stream containing phosgene (P) and at least one feed stream containing primary amines (A) to the reaction chamber through a nozzle assembly, where the amines are reacted above its boiling point with phosgene. The nozzle arrangement has a number of (n >= 1) nozzles parallelly oriented to the rotational axis of the tube reactor, and an open space surrounding the nozzles. The one of the feed streams is fed over the nozzles and the other is fed over the open space to the chamber. The chamber has at least one movable mixer rotor.
