Druck siedet das Salizylsantalol unter teilweiser Zersetzung bei zirka 250-2600. Das spezifische Gewicht ist 1'07.
Beispiel 3 : Darstellung des Ä t h y l k a r b o n a t e s.
1¸ kg Oleum Santali werden mit 1 kg wasserfreiem Pyridin in chloroform gelöst und allmählich unter Einhaltung einer Temperatur von zirka 15 C mit 1 kg Chlorkohlensäureester versetzt. Die Reaktionsmasse wird mit Wasser und verdünnter Salzsäure gewaschen, das Chloroform verdunstet und der Rückstand im Vakuum destilliert. Die Hauptmasse siedet unter 25 mm. Druck bei zirka 180-1850. Das spezifische Gewicht des erhaltenen Präparates beträgt 1-010 bei 150, das des Ausgangsmateriales 0#976. Mit alkoholischem Kali schwach erwärmt, scheidet das Präparat alsbald einen dicken Niederschlag von kohlensaurem Kali aus. Bei der Einwirkung von Phosgen auf Santelöl in Gegenwart von Pyridin erhält man den entsprechenden neutralen Kohlensäureester.
In der gleichen Weise wie in den angeführten Beispielen kann man auch durch

öles erhalten, welche dem genannten Zwecke genügen.

EMI2.1
The salicylsantalol boils under pressure with partial decomposition at around 250-2600. The specific weight is 1,07.
Example 3: Representation of the Ä t h y l k a r b o n a t e s.
1¸ kg of Santali oleum are dissolved with 1 kg of anhydrous pyridine in chloroform and 1 kg of chlorocarbonic acid ester is gradually added while maintaining a temperature of around 15 ° C. The reaction mass is washed with water and dilute hydrochloric acid, the chloroform is evaporated and the residue is distilled in vacuo. The main mass boils below 25 mm. Print at around 180-1850. The specific gravity of the preparation obtained is 1-010 at 150, that of the starting material 0 # 976. Warmed up slightly with alcoholic potash, the preparation soon excretes a thick precipitate of carbonate of potash. The action of phosgene on Santel oil in the presence of pyridine gives the corresponding neutral carbonic acid ester.
