摘要 |
Starting material streams are mixed in a mixer (13) for the phosgenation of amines by a process in which the reaction product (3) is removed in a closed loop and the starting material streams (1.2) contain organic solvents. The main streams (1.1, 2.1) and/or part-streams (1.2, 2.2) of the starting materials (1, 2) come into contact with one another according to the countercurrent principle. |
