Description
AUSGEGEBEN AM 11. JULI 1919ISSUED JULY 11, 1919
Durch das Hauptpatent 303805 ist ein Verfahren zur Reindarstellung von Glyzerin geschützt, welches darin besteht, daß man tech-. nische, glyzerinhaltige Flüssigkeiten mit Blei-Verbindungen behandelt und das Glyzerinblei zerlegt.The main patent 303805 protects a process for the pure preparation of glycerine, which consists in being tech-. niche, glycerine-containing liquids with lead compounds treated and dismantled the glycerine lead.
Es wurde nun gefunden, daß diese Zerlegung des Glyzerinbleis durch Erhitzen mit Wasser unter Druck den besonderen Vorteil bietet, daß direkt konzentriertet Glyzerinlösungen erhalten werden. Das Bleioxyd fällt in schwerer Form aus und kann leicht entj^ fernt werden.It has now been found that this decomposition of the glycerine lead by heating with Water under pressure has the particular advantage that directly concentrated glycerine solutions can be obtained. The lead oxide precipitates in a severe form and can easily be formed be removed.
575 Gewichtsteile Glyzerinblei von etwa 80 Prozent Trockengehalt, wie es nach Beispiel ι des Hauptpatentes erhalten wird, werden mit 600 Gewichtsteilen Wasser in einem Autoklaven unter Rühren auf 160 ° erhitzt und 2 Stunden bei dieser Temperatur gehalten. Dann wird das Rührwerk stillgesetzt und die Heizung entfernt. Nach einer weiteren halben Stunde wird durch ein Rohr, das bis kurz über den Bleiniederschlag heruntergeführt wird, eine fast klare Glyzerinlösung von etwa 16 Prozent abgezogen, die durch Kohlensäure vom Bleioxyd befreit und destilliert wird. Der im Autoklaven verbleibende Rückstand wird mit Wasser aufgeschlemmt und abgesaugt. Die erhaltene verdünnte Glyzerinlösung wird aufs neue mit Glyzerinblei versetzt und mit dieser wieder unter Druck erhitzt, während das erhaltene Bleioxyd zur' weiteren Abscheidung von Bleiglyzerin aus Rohglyzerin oder Schlempe verwandt wird.575 parts by weight of glycerine lead of about 80 percent dry content, as according to the example ι of the main patent is obtained with 600 parts by weight of water in one Autoclave heated to 160 ° with stirring and kept at this temperature for 2 hours. Then the agitator is stopped and the heating is removed. After another half Hour is led down through a pipe that comes down to just above the lead precipitation is, an almost clear glycerine solution of about 16 percent drawn off by carbonic acid is freed from lead oxide and distilled. The residue remaining in the autoclave is suspended with water and sucked off. The diluted glycerine solution obtained is added again with glycerine lead and heated with this again under pressure, while the lead oxide obtained is used for further separation of lead glycerine Raw glycerine or stillage is used.
