イソシアネートの製造方法
Document Type and Number:
Japanese Patent JP5883011
Kind Code:
B2
Abstract:
The invention relates to a method for producing isocyanates by reacting the corresponding amines with phosgene, comprising the following steps: (a) providing at least one amine-containing reactant flow and at least one phosgene-containing reactant flow, (b) mixing the reactant flows to form at least one reaction mixture in a mixing zone, (c) reacting the at least one reaction mixture in a reaction zone, and (d) processing the at least one product mixture obtained from (c), wherein (i) the mixing zone is composed of at least two strands which are connected in parallel and can be controlled separately from each other and which each comprise at least one mixing unit, or (ii) the reaction zone is composed of at least two strands which are connected in parallel and can be controlled separately from each other and which each comprise at least one reaction unit, or (iii) the mixing zone and the reaction zone are composed of at least two strands which are connected in parallel and can be controlled separately from each other and each comprise at least one mixing unit and at least one reaction unit.
