Title:
JET REACTOR WITH FLOW DUCTS AND PROCESS FOR PREPARING ISOCYANATES USING IT
Document Type and Number:
WIPO Patent Application WO/2009/023989
Kind Code:
A1
Abstract:
The present invention provides a jet reactor with flow ducts and a process for preparing isocyanates using it. The jet reactor with flow ducts situates the flow ducts in inner feed pipe which form cyclone and reinforce vortex, thereby amine steam rapidly admixes and reacts with phosgene, and the byproducts are reduced. In addition, the present process uses jet-absorb 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.
