  Verfahren zur Darstellung der antiseptisch wirkenden   6-Chlor-1-methyl-3-oxybenzol-     - 4-karbonsäuren.   



   Die   6-Halogen-l-methyl-3-oxybenzol-4-karbonsÅauren   sind bis jetzt nur nach einem   einzigen   sehr   umständlichen   und technisch unbrauchbaren Verfahren hergestellt worden (vgl. Berliner Berichte   26   [1893], Seite 1851). Die Produkte selbst sind völlig unbeachtet geblieben. 



   Der Erfindern ist es gelungen, ein Verfahren aufzufinden, welches die glatte technische Darstellung dieser wertvollen Desinfektionsmittel ermöglicht. 



   Es wurde gefunden, dass diese Säuren sich dadurch herstellen lassen, dass man-Chlor- 
 EMI1.1 
   umkristallisiert werden. Aus Wasser kristallisiert sie iu mikroskopischen Madeln, aus Alkohol   in flachen Prismen, Ihr Schmelzpukt liegt hei 205 .

  Process for the preparation of the antiseptic 6-chloro-1-methyl-3-oxybenzene- 4-carboxylic acids.



   The 6-halo-1-methyl-3-oxybenzene-4-carboxylic acids have hitherto only been produced by a single, very cumbersome and technically unusable process (cf. Berliner Reports 26 [1893], page 1851). The products themselves have been completely ignored.



   The inventors have succeeded in finding a method which enables the smooth technical representation of these valuable disinfectants.



   It has been found that these acids can be produced by adding -chlorine-
 EMI1.1
   be recrystallized. It crystallizes out of water in microscopic girls, out of alcohol in flat prisms, its melting point is hot.
