Verfahren zur Herstellung von 2r-Arylamino- 4 Process for the preparation of 2r-arylamino- 4th jj 6-diohlor-s-triazinen6-diochloro-s-triazines
Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Herateilung von 2-Arylamino-4,6-dichlor-s-triazinen durch Umsetzung von Cyanurchlorid mit Arylaminen im Molverhältnis 1 : 1 in wässrigem Medium; das Verfahren besteht darin, dass man die Arylamine in Form ihrer wasserlöslichen Salze einsetzt.The present invention is a method for Division of 2-arylamino-4,6-dichloro-s-triazines by Reaction of cyanuric chloride with arylamines in a molar ratio of 1: 1 in an aqueous medium; the procedure consists in that the arylamines are used in the form of their water-soluble salts.
Als wasserlösliche Ary!aminsalze kommen beispielsweise die Chlorhydrate und die Sulfate der Arylamine in Betracht. Als Arylamine seien beispielsweise Anilin, 2-Chloranilin, 3-0hloranilin, 4-Chloranilin, 2,4-Dichloranilin, 4-Methylanilin, 4-Methoxyanilin, 4-Cyananilin, 4~Bromanilin, N-Methylanilin und 2-Aminonaphthalin genannt.As water-soluble ary! Amine salts, for example Chlorhydrates and the sulfates of the arylamines into consideration. Examples of arylamines are aniline, 2-chloroaniline, 3-chloroaniline, 4-chloroaniline, 2,4-dichloroaniline, 4-methylaniline, 4-methoxyaniline, 4-cyananiline, 4 ~ bromaniline, N-methylaniline and called 2-aminonaphthalene.
Bas wässrige Medium, in dem die Umsetzung des Cyanurchlorids mit den wasserlöslichen Arylaminealzeη erfolgt, kann organische Lösungsmittel, beispielsweise Aceton, enthalten, es kann aber auch von organischen Lösungsmitteln frei sein.Bas aqueous medium in which the implementation of the cyanuric chloride takes place with the water-soluble Arylaminealzeη, organic Solvents, for example acetone, contain, but it can also be free of organic solvents.
Ea ist bekannt, 2-Arylamino-4,6-dichlor-s-triaaine durch Umsetzung von Cyanurchlorid mit Arylaminen in wässrigem Medium in der Weise herzustellen, dass man die Arylamine in Form der ** k ^0- 008849/1965Ea is known to produce 2-arylamino-4,6-dichloro-s-triaaine by reacting cyanuric chloride with arylamines in an aqueous medium in such a way that the arylamines are in the form of ** k ^ 0 - 008849/1965

freien Basen einsetzt. Ist in diesen Fällen das wässrige Medium frei von organischen Lösungsmitteln, dann liegen die Arylamine in ungelöstem Zustand vor und erschweren infolgedessen die Umsetzung sehr; enthällt das wässrige Medium jedoch organische Lösungsmittel, wie z.B. Aceton oder Äthylalkohol, dann können die Arylamine zwar in gelöstem Zustand vorliegen, es entstehen aber leicht unerwünschte Hebenprodukte.uses free bases. In these cases it is the watery one Medium free of organic solvents, then the Arylamines in the undissolved state and consequently make the implementation very difficult; however, the aqueous medium contains organic solvents such as acetone or ethyl alcohol, then the arylamines can be in a dissolved state, but undesirable by-products are easily formed.
Im Gegensatz hierzu lässt sich die Umsetzung des Cyanurchlorids mit Ary!aminen zu 2-Arylamino-4f6-dichlor-s-triazinen in wässrigem Medium bei dem erfindungsgemässen Verfahren ohne Erschwerung und ohne Bildung unerwünschter Nebenprodukte durchführen, gleichgültig, ob das wässrige Medium organische Lösungsmittel enthält oder hiervon frei ist.In contrast to this, the reaction of the cyanuric chloride with aryl amines to 2-arylamino-4 f 6-dichloro-s-triazines in an aqueous medium in the process according to the invention can be carried out without complication and without the formation of undesired by-products, regardless of whether the aqueous medium is organic Contains or is free from solvents.
Der Gedanke, die wasserunlöslichen Arylamine in Form ihrer wasserlöslichen Salze mit Mineralsäuren, wie Salzsäure oder Schwefelsäure einzusetzen, hat keineswegs nahegelegen, da die Umsetzung des Cyanurchlorids mit Aminen bislang stets unter Bedingungen durchgeführt worden ist, bei denen eine Bildung von Salzen der Amine mit Mineralsäuren gerade unterbunden wurde.The thought, the water-insoluble arylamines in the form of their Using water-soluble salts with mineral acids, such as hydrochloric acid or sulfuric acid, was by no means obvious, since the Implementation of the cyanuric chloride with amines has so far always been carried out under conditions in which formation by salts of amines with mineral acids has just been prevented.
Die nach dem erfinduhgsgemässen Verfahren erhaltenen 2-Arylamino· 4,6-dioülor-s-triazine sind bekannt; sie lassen sich u.a. als Pflanzenschutzmittel verwenden.The 2-arylamino obtained by the process according to the invention 4,6-diolor-s-triazines are known; they can be used as Use pesticides.
