Abstract

Vorgeschlagen wird ein Verfahren zur Herstellung von Diisocyanaten durch Gasphasenphosgenierung ausgehend von einem die entsprechenden Diamine sowie einem Phosgen enthaltenden Eduktstrom, wobei die Eduktströme jeweils getrennt in die Gasphase übergeführt und auf die Reaktionstemperatur der Gasphasenphosgenierung vorerhitzt werden, das dadurch gekennzeichnet ist, dass hierfür die Abwärme aus einer Anlage zur Herstellung von Chlor durch heterogenkatalysierte Oxidation von Chlorwasserstoff nach dem Deacon-Verfahren genutzt wird.
