Abstract

This disclosure relates to a static mixer (1) with a plurality of nozzles, and more generally, to a mixer and method of use thereof for mixing phosgene and amine with shaped jets or at least two rows of nozzles (15,16) where the second row (16) is used to enrich an area of deficit of the phosgene flow within the static reactive jet mixer (1). Configurations of enriching secondary flow include the use of concentric, eccentric, or offset jets of amine/phosgene, and the use of nozzles with different and irregular geometries to help focus amine/phosgene to a specific area of the principal phosgene flow.
