  Verfahren zur Darstellung von   Brom- und Jodlezithin.   



   Den Gegenstand der vorliegenden Erfindung bildet ein Verfahren, mittelst welchem ans Lezithin in sehr einfacher Weise   Brom-und Jodlezithin hergestellt   werden kann, das sich gegen- über den bisher dargestellten derartigen Präparaten dadurch auszeichnet, dass dasselbe von dem durch die Verwendung des Chloroform entstehenden unangenehmen Geruch und Geschmack vollkommen frei ist. 



   Das vorliegende Verfahren besteht nur darin, dass Lezithin in Tetrachlorkohlenstoff   gelöst   
 EMI1.1 
 wähnte Menge Bromwasserstoffsäure ist etwas geringer als diejenige Menge, die zur Darstellung von Bromlezithin mit 25% Bromgehalt erforderlich ist. Die nach dem   Rütteln   erhaltene Masse wird   behufs Neutralisierung der Bromwasserstoffsä@re mit 150 g wasserfreiem, kalzinierten     Natriumkarbonat   vermischt und diese Mischung durch 50 g auf ein Filter   gelegtes kalziniertes   Natriumkarbonat abermals filtriert.

   Von der filtrierten Mischung sird der Tetrachlorkohlenstoff in einem Vakuumapparate abdestilliert und die   zurückgebliebene   Masse, die bereits fertiges Bromlezithin ist, behufs Austreiben   der noch enthaltenen geringfügigen Feuchtigkeit, im evakuierten

  Process for the preparation of bromo- and iodolecithin



   The subject matter of the present invention is a process by means of which bromo- and iodine-lecithin can be produced in a very simple manner on the lecithin, which is distinguished from the preparations of this type previously presented in that it has the unpleasant odor resulting from the use of chloroform and taste is completely free.



   The present method consists only of lecithin being dissolved in carbon tetrachloride
 EMI1.1
 Mentioned amount of hydrobromic acid is somewhat less than that amount which is required to prepare bromolecithin with 25% bromine content. The mass obtained after shaking is mixed with 150 g of anhydrous, calcined sodium carbonate to neutralize the hydrobromic acid, and this mixture is filtered again through 50 g of calcined sodium carbonate placed on a filter.

   The carbon tetrachloride is distilled off from the filtered mixture in a vacuum apparatus and the remaining mass, which is already finished bromolecithin, is evacuated to drive out the slight moisture it still contains
 EMI1.2
