Title:
イソシアネートの製造方法
Document Type and Number:
Japanese Patent JP2012505850
Kind Code:
A
Abstract:
The invention relates to a process for preparing isocyanates by reacting the corresponding amines with phosgene in the gas phase, if appropriate in the presence of an inert medium, in which the amine and the phosgene are first mixed and converted to the isocyanate in a reactor, and in which a reaction gas which comprises isocyanate and hydrogen chloride and leaves the reactor is cooled in a quench space of a quench by adding a quench medium. The quench medium on addition to the quench space has a temperature above the condensation temperature or the desublimation temperature of the reaction gas.
