FIELD: process engineering.
SUBSTANCE: isocyanates are produced in interaction between organic amine and phosgene. Proposed method comprises three stages: First stage is executed in dynamic mixer. Second stage is executed in one reactor. Third stage is performed in one separator. Pressure in second stage reactor should exceed or equal that in first stage dynamic mixer. Pressure in third stage separator should be lower than that in second stage reactor.
EFFECT: optimum mixing conditions.
