CONTINUOUS PROCESS FOR THE PREPARATION OF ORTHO-SUBSTITUTED ANILINES IN A FLOW REACTOR

摘要

Continuous method for producing ortho-substituted anilines in a flow reactor Continuous process for preparing ortho-substituted anilines of the formula in a flow reactor in the presence of a nitrogen base not having an NH group, and multistage process for preparing herbicidal N-alkyl-N-[2-(1,3,5-triazin-2-ylcarbonyl)-phenyl]alkansulphonamides of the formula (4-1) wherein the continuous process for preparing ortho-substituted anilines of the formula (4) in a flow reactor constitutes the first process step of the multistage process for preparing the herbicidal active ingredients of the formula (4-1).
