Title:
フローダクトを備えるジェット式反応装置、及びフローダクトを備えるジェット式反応装置を用いたイソシアネート類製造方法
Document Type and Number:
Japanese Patent JP5595271
Kind Code:
B2
Abstract:
The present invention provides a flow duct type jet reactor and a process for preparing isocyanates using it. The flow duct type jet reactor situates flow ducts in inner feed pipe which form whirlpool and reinforce vortex, thereby amine steam rapidly admixes and reacts with phosgene, and the byproducts are reduced. In addition, the present process uses a jet-absorption apparatus which rapidly cools the high temperature gas discharged from the reactor to a temperature at which the product is thermally stable, and at the same time provides negative pressure for the reaction process of the system, and thus saving bulky vacuum system.
