  Verfahren zur Darstellung von   Polyglyzerinen aus Glyzerin.   
 EMI1.1 
 glyzerin durch Erhitzen von Glyzerin unter Atmosphärendruck unter gleichzeitiger Entfernung des sich bildenden Wassers darstellen kann. Nach diesem Verfahren vollzieht sich die Bildung der kondensierten Glyzerine nur   langsam.   So erfordert es z. B. unter den in der genannten Patentschrift gegebenen Bedingungen mindestens 5 bis 6 Stunden Erhitzens, bis eine Mischung von 60 Prozent   Diglyzerin und   40 Prozent Glyzerin erhalten wird. Es 
 EMI1.2 
   heisst,   dass man dem zu kondensierenden Glyzerin vor dem Erhitzen geringe Mengen von Alkali (Ätznatron, Ätzkali, Schwefelalkali, alkalisch reagierende Seifen und ähnliches) zugibt. 



  So ist es   möglich,   die Kondensation in etwa 1/10 der bisher erforderlichen Zeitdauer auszuführen. 
 EMI1.3 
 Sprengstoffen Verwendung findet oder   zur   Herstellung von plastischen Massen oder in der Textilindustrie dienen Roll.

  Process for the preparation of polyglycerines from glycerine.
 EMI1.1
 glycerine can be produced by heating glycerine under atmospheric pressure while removing the water that forms. According to this process, the formation of the condensed glycerine takes place only slowly. So it requires z. B. under the conditions given in said patent at least 5 to 6 hours of heating until a mixture of 60 percent diglycerol and 40 percent glycerol is obtained. It
 EMI1.2
   means that small amounts of alkali (caustic soda, caustic potash, alkali sulfur, alkaline soaps and the like) are added to the glycerine to be condensed before heating.



  It is thus possible to carry out the condensation in about 1/10 of the time previously required.
 EMI1.3
 Explosives is used or for the production of plastic masses or serve in the textile industry roll.
