 oder in einer Kugelmühle oder in sonst geeigneter Weise energisch durchgemischt. Man lässt hierauf die Flüssigkeit zur klaren Abscheidung einige Zeit ruhig stehen, zieht das obenstehend alkoholische Extrakt ab, entfärbt dasselbe eventuell mit Kohle, filtriert und dampft den Alkohol, welcher hiebei fast vollständig wieder gewonnen wird, bis zur Siruplionsistenz des Rückstandes ab. Das erhaltene Rohprodukt kann von geringen Verunreinigungen durch nochmaliges Lösen in wenig lionzentriertem Alkohol'und Filtrieren gereinigt werden.

   Um dasselbe in reines salzsaures Betain überzuführen, versetzt man den so erhaltenen gereinigten Auszug unter Kühlung mit Salzsäure in geringem Überschuss in gasförmiger Form oder als konzentrierte wässerige Salzsäure oder konzentrierte alkoholische Salzsäure und lässt unter Kühlung zur Kristallisation stehen. Die Kristallmasse wird abgesaugt und durch Umkristallisieren aus Alkohol in völlig reiner Form gewonnen. Desgleichen ergeben die Mutterlaugen nach entsprechender Einengung weitere Mengen Betainchlorhydrat. 



   Bei Anwendung von Melasse an Stelle von Melasseschlempe ist das Verfahren genau das gleiche, nur ist die Ausbeute entsprechend dem geringeren Gehalt der Melasse an Betain eine entsprechend niedrigere. Dasselbe gilt bei Anwendung von anderen Abläufen der   Rübonzuckerfabrikation.

 or vigorously mixed in a ball mill or in some other suitable manner. The liquid is then left to stand for a while for a clear separation, the above alcoholic extract is drawn off, it may be decolorized with charcoal, filtered and the alcohol, which is almost completely recovered, is evaporated until the residue is syrupy. The crude product obtained can be cleaned of minor impurities by dissolving it again in a little lion-centered alcohol and filtering.

   In order to convert it into pure betaine hydrochloric acid, the purified extract obtained in this way is mixed with a slight excess of hydrochloric acid in gaseous form or as concentrated aqueous hydrochloric acid or concentrated alcoholic hydrochloric acid while cooling and allowed to crystallize while cooling. The crystal mass is sucked off and obtained in a completely pure form by recrystallization from alcohol. Likewise, the mother liquors produce further amounts of betaine chlorohydrate after appropriate concentration.



   When using molasses instead of molasses mash, the process is exactly the same, only the yield is correspondingly lower in accordance with the lower betaine content of the molasses. The same applies to the use of other turnip sugar manufacturing processes.
