Description

  

  Verfahren zur     Herstelltineines        liarzartigeu        Stoffes.       Bekanntlich entstehen durch     Kondeiis.Ltioii     von     Phenolen    mit Aldehyden,     insbesondere     Formaldehyd, in alkalischer, saurer oder neu  traler Lösung Produkte, die harzartigen     t'lia-          rakter    haben.  



  Die älteren dieser     Verfahren    liefern in  der Regel     übelriechende,    durch     Wirkung        voll     Luft und Licht nachdunkelnde und morsch  und bröcklig werdende Körper. Dieselben       Veränderungen    erleiden naturgemäss auch die  daraus hergestellten Lackanstriche und Poli  turen.  



  Die neueren Verfahren, welche diese -Übel  stände beseitigen wollen, erfordern entweder  besonders reines Ausgangsmaterial, wie es  in den technischen     Phenolgeniischen    nicht  geboten wird, oder     grössere    Mengen saurer.  entweder gar nicht oder nur auf     umständlichem     Wege     regenerierbarer    Kondensationsmittel.  



  Sie liefern ferner sämtlich entweder     alkali-          lösliehe,    oder in den üblichen für Lacke in  Betracht kommenden     Lösungsmitteln        nur        schi-          schwer    lösliche Produkte.

           f:s    hat sich     nun    gezeigt,     dass    das     Konden-          sationsprodukt    aus technischem     Kresol    und  Formaldehyd in einen neuen, völlig neutralen,  in Benzol.     llzetoii        usw.    leicht     licsliclieii,    sehr  harten,     spr;;den,        hochschmelzenden,    Hellgelben,  durchsichtigen;

   an Licht und     Luft        unveränder-          lichen        Körper        von    Harzhabitus     übergeführt     wird, wenn es vorteilhaft in alkalischer     Lösung     mit     p-Toluolsulfoclilorid        behandelt    wird.  



       Beispiel   <I>I:</I>  100 g des nach einer der bekannten       Methoden        lierge@st < llten        ]ii-esolallsoliols    raus       technischem        Kresolgeinisch)

          werden    in     einem          geringen        @rberscliufi        verdünnter        Natronlauge          gelöst    und bei einer     Temperatur        rieht        über          30         nüt    einer Lösung von     137    g     p-Toluol-          su@f@ch@orid    in     :

  500    g Benzol mehrere Stunden       gerührt.    Die     Benzolsehicht,    die das Produkt       enthält,    wird von eventuell anhaftender     Lauge          gewaschen.        getrocknet        lind    das Benzol ab  getrieben.

   Das     zurückgebliebene        Hellgelbe,     harte     Produkt    ist in jeder Beziehung den       natürlichen    Harzen. wie     Kolial        usw.,        ähnlich.         <I>Beispiel</I>     Ir     100 g     Formalinkondensationsprodukt,    leer  gestellt aus der Fraktion     215-220"    des       technischen        Kresols    (also im wesentlichen aus  den     Xy        lenolen        1:2':4,    1:3:4 und<U>1:4:

  2</U>  bestehend), werden in einen geringen     L'ber-          schufi        verdiinnter    Natronlauge gelöst     und    bei  einer Temperatur nicht über 30   mit einer  Lösung von<B>137</B> g     p-Toluolsulfochlorid    in  500 g Benzol mehrere Stunden gerührt.  



  Die     Weiterverarbeitung    erfolgt dann wie  in Beispiel I, das entstandene Produkt hat  genau die gleichen Eigenschaften wie das  nach Beispiel I erhaltene.



  Process for the manufacture of a resin-like substance. It is well known that the condensation of phenols with aldehydes, in particular formaldehyde, in alkaline, acidic or neutral solutions gives rise to products that are resinous in character.



  The older of these methods usually produce foul-smelling bodies, which darken after exposure to air and light, and which become rotten and crumbly. The same changes naturally also suffer from the lacquer coatings and polishes produced from them.



  The newer processes, which want to eliminate these -Übel stands, either require particularly pure starting material, as it is not offered in the technical phenol geniic, or larger amounts of acidic. condensation agents that cannot be regenerated at all or only in a cumbersome way.



  Furthermore, they all provide products that are either alkali-soluble or only sparingly soluble in the usual solvents used for paints.

           f: s has now been shown that the condensation product of technical cresol and formaldehyde is transformed into a new, completely neutral one, benzene. llzetoii etc. slightly licsliclieii, very hard, brittle; den, high-melting, light yellow, transparent;

   A body which is unchangeable in light and air is converted from resinous habit when it is advantageously treated in an alkaline solution with p-toluenesulfocliloride.



       Example <I> I: </I> 100 g of lierge @ st <llten] ii-esolalloliols according to one of the known methods out of technical cresolgine)

          are dissolved in a small amount of dilute sodium hydroxide solution and at a temperature of over 30 minutes, a solution of 137 g of p-toluene-su @ f @ ch @ orid in:

  500 g of benzene stirred for several hours. The benzene layer containing the product is washed from any lye that may have adhered. dried and driven off the benzene.

   The remaining pale yellow, hard product is in every respect natural resins. like colial etc., similar. <I> Example </I> Ir 100 g formalin condensation product, left blank from fraction 215-220 "of technical cresol (i.e. essentially from the xylenes 1: 2 ': 4, 1: 3: 4 and <U> 1 : 4:

  2), are dissolved in a small amount of diluted sodium hydroxide solution and stirred for several hours at a temperature not exceeding 30 with a solution of 137 g of p-toluenesulfonyl chloride in 500 g of benzene .



  The further processing then takes place as in example I, the resulting product has exactly the same properties as that obtained according to example I.
