Zur Darstellung der sogenannten Salole (Aether der Salicylsäure mit den Phenolen) wird wie folgt verfahren:To represent the so-called salols (ethers of salicylic acid with phenols) is done as follows:
58 kg Phenolnatrium und 80 kg salicylsaures Natrium werden in gepulvertem Zustande in einem mit Rührwerk und Rückflufsrohr versehenen gufseisernen Kessel innigst gemischt und sodann der Einwirkung des Phosgens ausgesetzt. Es vollzieht sich hierauf unter erheblicher Erhitzung eine lebhafte Reaction, welche nach dem Erkalten des Gefäfses durch mäfsiges Erwärmen zu Ende geführt wird. Aus dem Reactionsproduct kann man den Aether vortheilhaft durch Einleiten von Wasserdampf austreiben; derselbe sammelt sich in Form von Oeltropfen unter dem Wasser an, wird am besten durch Einwerfen eines Krystalls zur Erstarrung gebracht und sodann aus verdünntem Alkohol umkrystallisirt.58 kg of sodium phenol and 80 kg of sodium salicylic acid are powdered in intimately mixed in a cast iron kettle equipped with a stirrer and reflux pipe and then exposed to the action of phosgene. It then takes place under considerable circumstances Heating - a lively reaction, which, after the vessel has cooled, by moderate Heating is completed. The ether can be advantageously obtained from the reaction product expel by introducing steam; it collects in the form of Oil drops under the water, is best achieved by throwing in a crystal Solidified and then recrystallized from dilute alcohol.
Es kann auch in folgender Weise verfahren werden:It can also be done in the following way:
Man bringt (zweckmäfsig in dem oben erwähnten Rührkessel) trockenes Phenolnatrium, erwärmt im OeI- oder im Luftbad, am besten auf 150 bis i8o° G. und leitet Phosgengas in schwachem Strom ein, während man das Rührwerk langsam umlaufen läfst. Die Masse erweicht, und nach verhältnifsmäfsig kurzer Zeit ist die Reaction vollendet. Die Gewinnung des reinen Aethers aus der Reactionsmasse kann auch in diesem Falle leicht durch Behandlung mit Wasserdampf und nachheriges Umkrystallisiren bewirkt werden.Bring dry sodium phenol (expediently in the stirred tank mentioned above), heated in an oil bath or in an air bath, preferably to 150 to 180 ° G. and conducts phosgene gas in weak current while slowly turning the agitator. The mass softens and in a comparatively short time the reaction is complete. The extraction In this case, too, the pure ether from the reaction mass can easily be obtained by treatment with steam and subsequent recrystallization.
