Continuous reaction process of cyanuric acid fluoride and amine

摘要

The present invention relates to a process for the simultaneous introduction of a cyanuric acid fluoride and an aqueous amine solution simultaneously and continuously into a pipe with static mixing elements in a constant mass stream such that the molar ratio of cyanuric acid fluoride to amine is in the range of 1: 1 to 1.5: 1, Adjust the pH of the aqueous reaction mixture after intensive forced mixing and exiting the static mixer to 5.5 to 7.0 by means of an inorganic alkaline medium. From the cyanuric acid fluoride and amine, 1-amino-3,5-difluoro-s-/RTI triazinyl compounds.
