Description

  

  Verfahren zur Herstellung eines     Zwisehenproduktes    der Teerfarbenindustrie.    Das     l.-Chlor-2-naphthylthioglykolsäure-          chlorid    ist bekanntlich ein sehr wertvolles  Zwischenprodukt der Teerfarbenindustrie.  Es wurde gefunden,     dass    man sehr leicht und  in vorzüglicher Ausbeute zu dieser Verbin  dung gelangen kann, wenn man das     2-Naph-          thylthioglykolsäurechlorid    mit chlorierenden  Mitteln behandelt.

      <I>Beispiel:</I>  218 Teile     f-Naphthyltliioglyli:olsäure    wer  den in<B>600</B> Teilen eines geeigneten Ver  teilungsmittels,, wie Chlorbenzol oder     Tetra-          chlorätha.n,    suspendiert und 1.40 Teile     PCl3     beigegeben. Hierauf wird während zwei  Stunden auf 80 bis 100   C erhitzt.

   Nach  Verdünnung der entstandenen Lösung des       ss-Naphtliyltliioglykoylchlorids    mit 800 Tei  len des verwendeten Verteilungsmittels lässt  man nach Zugabe einer geringen Menge  eines Überträgers (zum Beispiel 2     gr        Ferri-          ehlorid    oder     Antimonpentachlorid)    innert  einer halben     ,Stunde    bei 0 bis 5   135 Teile         Sulfurylchlorid        eintropfen.    Das Reaktions  gemisch wird während mehrerer Stunden  weiter gerührt, hierauf auf die Temperatur  des Arbeitsraumes steigen gelassen und zur  Vervollständigung der Reaktion einige Stun  den bei dieser Temperatur gehalten.

   Die so  erhaltene Lösung des     1-Chlor-2-naphthylthio-          glykoylchlorides    ist, gegebenenfalls nach       Vertreibung    der vom     Sulfurylchlorid    stam  menden schwefligen Säure, direkt zur Wei  terverarbeitung geeignet. Die Ausbeuten  sind vorzüglich, besonders wenn man unter  Ausschluss von Licht arbeitet:



  Process for the manufacture of a toe product in the tar paint industry. The l-chloro-2-naphthylthioglycolic acid chloride is known to be a very valuable intermediate product in the tar color industry. It has been found that this compound can be obtained very easily and in excellent yield if the 2-naphthylthioglycolic acid chloride is treated with chlorinating agents.

      <I> Example: </I> 218 parts of f-naphthyltliioglyli: oleic acid are suspended in <B> 600 </B> parts of a suitable distribution agent, such as chlorobenzene or tetrachloroethane, and 1.40 parts of PCl3 are added. This is followed by heating to 80 to 100 ° C. for two hours.

   After diluting the resulting solution of β-naphthyltliioglykoyl chloride with 800 parts of the distribution agent used, after adding a small amount of a carrier (for example 2 g of ferric chloride or antimony pentachloride), within half an hour at 0 to 5 135 parts of sulfuryl chloride are added dropwise. The reaction mixture is stirred for several hours, then allowed to rise to the temperature of the working space and kept at this temperature for a few hours to complete the reaction.

   The solution of 1-chloro-2-naphthylthioglykoylchlorides obtained in this way is directly suitable for further processing, if necessary after expelling the sulphurous acid originating from the sulphuryl chloride. The yields are excellent, especially if you work with the exclusion of light:
