 mittelindustrie anbelangt, da die Produkte auf Grund ihrer Wirksamkeit sowie ihrer absoluten Unschäd-   l1chkeit   ganz besonders für dieses spezielle Gebiet praktischer Verwendung zu empfehlen sind. 



   Schliesslich ist noch erwähnenswert, dass mit den nach dem erfindungsgemässen Verfahren hergestellten Produkten hinsichtlich des Schaumvermögens ein extrem weiter Bereich von praktisch Null bis zu sehr hohen Werten erzielbar ist. Diese Eigenschaft ermöglicht die Verwirklichung zahlreicher interessanter Entwicklungen, da es Fälle gibt, in denen hohe Waschkraft zusammen mit möglichst geringer Schaumbildung erwünscht ist. 



    PATENTANSPRÜCHE :    
1. Verfahren zur Herstellung oberflächenaktiver Stoffe, bei welchem ein Glyzerid mit einem Alkohol in flüssiger Phase, vorzugsweise in einem inerten organischen Lösungsmittel, in Gegenwart von Carbonaten, Alkylaten oder Phosphaten von Alkalimetallen als Katalysatoren, umgeestert wird, dadurch gekennzeichnet, dass man das Glyzerid mit Xylit etwa 6-16 Stunden lang bei Temperaturen von 20 bis etwa   1200C   umsetzt.

 medium industry, as the products are particularly recommended for this special area of practical use due to their effectiveness and their absolute harmlessness.



   Finally, it is also worth mentioning that with the products manufactured by the process according to the invention, an extremely wide range from practically zero to very high values can be achieved with regard to the foaming power. This property enables the realization of numerous interesting developments, since there are cases in which high washing power together with the lowest possible foam formation is desired.



    PATENT CLAIMS:
1. A process for the preparation of surface-active substances, in which a glyceride with an alcohol in the liquid phase, preferably in an inert organic solvent, in the presence of carbonates, alkylates or phosphates of alkali metals as catalysts, is transesterified, characterized in that the glyceride with Xylitol reacts for about 6-16 hours at temperatures from 20 to about 1200C.
