Title:
穴噴射型リアクターおよびこれを用いたイソシアナートの製造方法
Document Type and Number:
Japanese Patent JP2010504918
Kind Code:
A
Abstract:
The present invention relates to a hole-jetting type reactor and its applications, in particular to a process for the production of isocyanates by the phosgenation of aliphatic or aromatic diamines or triamines in the gas phase using this reactor. The present invention achieves a good mixing and reacting result of the gas-phase phosgenation reaction at a high temperature by improving the mixing of reactants in the reactor to reduce the possibility of forming swirls and eliminate negative pressure produced at a local jet area, which can finally reduce back-mixing and formation of solid by-products.
