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 le pinène par le camphène et l'acide benzoylebenzoïque par de l'acide té- traehlorbenzoylebenzoïque, tout en obtenant un résultat analogue à celui du procédé du brevet principal, l'éther bornéolique obtenu étant facilement saponifiable au moyen de soude caustique aqueuse.
<I>Exemple:</I> 100 kg de camphène sont chauffés avec 50 kg d'acide tétrachlorbenzoylebenzoïque à 140 C. Après 9 heures, plus de 80 % de l'acide sont transformés en éther isobornéoli- que. L'excès de camphène est alors distillé à la vapeur d'eau, le résidu est chauffé avec de la lessive de soude à 20 % jusqu'à saponi fication complète et l'isobornéol est séparé à la vapeur d'eau.
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, pinene can be replaced by camphene and benzoylbenzoic acid by tetrahlorbenzoylebenzoic acid, while obtaining a result analogous to that of the process of the main patent, ether. borneol obtained being easily saponifiable by means of aqueous caustic soda.
<I> Example: </I> 100 kg of camphene are heated with 50 kg of tetrachlorbenzoylebenzoic acid at 140 C. After 9 hours, more than 80% of the acid is converted into isoborneolic ether. The excess camphene is then distilled off with water vapor, the residue is heated with 20% sodium hydroxide solution until complete saponification and the isoborneol is separated with water vapor.
