Description

  

  Procédé pour la     fabrication    d'un     bornéol.       L'objet de la revendication du brevet  principal est un procédé pour la fabrication  d'un     bornéol,    suivant lequel on condense du       pinène    avec de l'acide     benzoylebenzoïque     pour produire un éther     bornéolique    facile  ment saponifiable.  



  Or, il a été trouvé qu'on peut     remplacer     dans ce procédé     l'acide        benzoylebenzoïque     par de l'acide     dichlorbenzoylebenzdïque,    tout  en obtenant un résultat analogue à celui du  procédé du brevet principal, l'éther     bornéoli-          que    obtenu étant facilement     saponifiable    au  moyen de soude     caustique    aqueuse.

      <I>Exemple:</I>  3 parties de     d-pinène    provenant du     pinus          halepensis,    connu sous le nom d'essence de  térébenthine grecque, sont chauffées à 130  C,  en     agitant    bien, avec 1 partie d'acide di-         chlorobenzoylebenzoïque    -obtenu par traite  ment d'acide     dichlorophtalique    anhydre avec  du benzène et du chlorure d'aluminium.  .près dissolution, le     pinène    qui n'est pas en  tré en réaction est distillé à. la vapeur d'eau,  le résidu est saponifié avec la quantité théo  rique de soude caustique et le     d-bornéol    ob  tenu est entraîné à la vapeur d'eau.

   Le ren  dement s'élève à     environ    85 % du     pinène     consommé.



  Process for the manufacture of a borneol. The object of the main patent claim is a process for the manufacture of borneol, wherein pinene is condensed with benzoylbenzoic acid to produce an easily saponifiable borneol ether.



  Now, it has been found that, in this process, benzoylbenzoic acid can be replaced by dichlorbenzoylebenzdic acid, while obtaining a result similar to that of the process of the main patent, the borneol ether obtained being easily saponifiable with medium aqueous caustic soda.

      <I> Example: </I> 3 parts of d-pinene from pinus halepensis, known as Greek turpentine, are heated to 130 C, stirring well, with 1 part of dichlorobenzoylebenzoic acid - Obtained by treating anhydrous dichlorophthalic acid with benzene and aluminum chloride. .after dissolution, the pinene which is not in very reaction is distilled at. water vapor, the residue is saponified with the theoretical quantity of caustic soda and the d-borneol obtained is entrained with water vapor.

   The yield is around 85% of the pinene consumed.
