Verfahren und Vorrichtung zur kontinuierlichen Herstellung von organischen Mono- oder Polyisocyanaten

摘要

The invention relates to a method for mixing educt streams in a mixer (13) for phosgenating amines. According to said method, the reaction product (3) is led off in a closed manner and the educt streams (1, 2) contain organic solvents. The main streams (1.1, 2.1) and/or partial streams (1.2, 2.2) of the educts (1, 2) meet countercurrently.
