More Information
Summary:Phosgene is mixed with an organic polyamine to produce polyisocyanate compounds. A phosgene flow is established in a conduit (15), and the organic polyamine is injected into the phosgene flow. A constricted region (4) of the conduit (15) resides downstream of the point of the polyamine injection. The presence of the constricted region (4) reduces by-product formation.
