  Verfahren zur Herstellung eines als Schutz- und     Isolierlack,        Imprägnierungsmittel,          Klebstoff    und dergleichen     verwendbaren    Harzes.    Es wurde gefunden, dass man zu einem  als Schutz- und Isolierlack,     Imprägnierungs-          mittel,    Klebstoff und dergleichen verwend  baren Harzes     gelangen    kann, indem man das  durch     Schwefelung        von        a-Naphthol    erhaltene  Harz mit     Acetylierungsmitteln    behandelt.  



  Die     Acetylierung        erfolgt    in üblicher  Weise,     sei    es durch Verwendung von     Essig-          säureh.alo,genid        bezw.        -anhydrid,    oder vermit  telst der freien Essigsäure in Gegenwart  eines Kondensationsmittels, wie zum Beispiel  gasförmiger Salzsäure,     Thionylchlorid,    Phos  phor- oder     Schwefelhalogenide    usw.  



  Gegebenenfalls kann die     A@cetylierung    in  Gegenwart eines Lösungsmittels,     wie    zum  Beispiel wässeriges Alkali,     Pyridin,        Toluol     und     dergleichen    vorgenommen werden.  



  Bei der Aufarbeitung des Harzes ist       zweckmässigerwcise    darauf zu achten, dass ein  eventueller Säure- oder     A1kaliüberschuss,    so  wie das Lösungsmittel restlos .entfernt wer  den. Das Trocknen erfolgt     vorteilhaft    bei  möglichst niedriger Temperatur,     geggebenen-          falls    unter Verwendung von Vakuum.         Dias    neue Harz ist wie das Ausgangsharz       von:    hell- bis     braungelber    Farbe. Es ist in  Alkohol und Alkali unlöslich.

   Es löst sich  in Äther,     Aceton,    Chloroform,     Äthylenchlo-          ri.d    und andern     halogenierten    Kohlenwasser  stoffen, ferner in aromatischen und hydrier  ten aromatischen     Kohlenwasserstoffen.    Das  Harz ist     weiterhin    auch löslich in einem     Ge-          misch    von Aceton und einem nicht lösenden  Lösungsmittel, wie zum Beispiel Alkohol.  Unter     1Vlitverwendung    von     Benzylalkohol,          Cyclehexanol    und dergleichen, lässt sich das  Harz auch in Leinöl lösen.

   Es ist ferner sehr       beständig    und widerstandsfähig gegen     physi-          kal.is,che    und     chemische    Einwirkungen, wie  zum Beispiel Witterungseinflüsse, mechani  sche Beanspruchung,     elektrische    Spannungs  unterschiede     und    chemische Reagenzien.  



  Dank diesen Eigenschaften eignet sich  das Harz insbesondere als Schutz- und     Iso-          lierlack,        Imprägnierungsmittel,    Klebstoffe       etc.    Zur Erhöhung der Elastizität und des  Lösungsvermögens können ihm die     üblichen     Zusätze, wie zum Beispiel Triphenylphos-           ph.at,        Cyclohexanol,    Kampfer oder     Iia.nipfer-          ersatzprodukte,    ferner Naturharze, beige  mischt werden.

   Da es sich weiterhin in ge  wissen Lösungsmitteln mit     Celluloseester    und       Kautschuk    in beliebigen     Mengen    mischen  lässt, kommt es     auch    als Füllmittel für     Cellu-          loseester    und     Kautschukfabrikate,    sowie als       lIärtungsmittel    für     Kautschuk    in     Frage.     Seine oben erwähnte     Leinöllöslichkeit    in Ver  bindung mit     Benzylalkohol    und dergleichen,  macht das Harz als Emaillack geeignet.  



       Beispiel:     <B>100</B> Teile     a-Naphtholschwefelharz    (erhal  ten zum     Beispiel    nach dem Patent Nr.     10d-015     durch Erhitzen von 150 Teilen     a-Naphthol,          \?5    Teilen Schwefel und 1 Teil     Na.trium-          hydroxyd)    werden in 50 Teilen Benzol gelöst  und mit 55 Teilen     Essigsäurea,nhydri.d    in Re  aktion gebracht.

   Nachdem     die        Veresterung     beendet ist, wird die gebildete Essigsäure,  das Benzol und das gebildete     Wasser    im     Va:          kuum    abgetrieben.



  Process for the production of a resin which can be used as a protective and insulating varnish, impregnating agent, adhesive and the like. It has been found that a resin which can be used as a protective and insulating varnish, impregnation agent, adhesive and the like can be obtained by treating the resin obtained by sulphurizing α-naphthol with acetylating agents.



  The acetylation takes place in the usual way, be it by using acetic acid halo, genid or. -anhydride, or mediated the free acetic acid in the presence of a condensing agent, such as gaseous hydrochloric acid, thionyl chloride, phosphorus or sulfur halides, etc.



  If necessary, the acetylation can be carried out in the presence of a solvent, such as, for example, aqueous alkali, pyridine, toluene and the like.



  When working up the resin, it is advisable to ensure that any excess acid or alkali, as well as the solvent, are completely removed. The drying is advantageously carried out at the lowest possible temperature, if necessary using a vacuum. The new resin is like the original resin from: light to brownish yellow color. It is insoluble in alcohol and alkali.

   It dissolves in ether, acetone, chloroform, ethylene chloride and other halogenated hydrocarbons, and also in aromatic and hydrogenated aromatic hydrocarbons. The resin is also soluble in a mixture of acetone and a non-dissolving solvent such as alcohol. With the use of benzyl alcohol, cyclehexanol and the like, the resin can also be dissolved in linseed oil.

   It is also very stable and resistant to physical, chemical and chemical effects, such as the effects of weather, mechanical stress, electrical voltage differences and chemical reagents.



  Thanks to these properties, the resin is particularly suitable as a protective and insulating varnish, impregnation agent, adhesive, etc. The usual additives such as triphenylphosphate, cyclohexanol, camphor or Iia.nipfer can be added to increase the elasticity and the dissolving power - substitute products, furthermore natural resins, are mixed in beige.

   Since it can still be mixed with cellulose ester and rubber in any quantity in certain solvents, it can also be used as a filler for cellulose esters and rubber products, and as a hardening agent for rubber. Its above-mentioned linseed oil solubility in connection with benzyl alcohol and the like makes the resin suitable as an enamel paint.



       Example: <B> 100 </B> parts of a-naphthol sulfur resin (obtained for example according to patent no. 10d-015 by heating 150 parts of a-naphthol, 5 parts of sulfur and 1 part of sodium trium hydroxide) are dissolved in 50 parts of benzene and reacted with 55 parts of acetic acid, nhydri.d.

   After the esterification has ended, the acetic acid formed, the benzene and the water formed is driven off in a vacuum.
