USE OF A PISTON REACTOR TO IMPLEMENT A PHOSGENATION PROCESS |
摘要 |
A process for phosgenating an amine comprising employing a plug-flow type reactor with internal recycle is disclosed. The process can be continuous, which makes it possible to prepare, in a single stage, a (poly)isocyanate with a good yield, without formation of byproducts and on simplifying the plant in order to carry out the process so as to promote safety. |
