Abstract

Abstract Translated from German Glycerinäther-phosphatide der Formel worin zwei der Reste R 1 , R 2 und R 3 C 10-30 -Alkylreste mit mindestens 8 C-Atomen in gerader Kette darstellen, wobei mindestens einer dieser Reste durch mindestens 2 C 1-3 -Alkylreste substituiert ist und die Summe der C-Atome in beiden Resten grösser als 20 ist; und der dritte Rest ein Rest - P(O)(O - )OR 4 ist, worin R 4 einen durch eine quaternäre Ammoniumgruppe substituierten nieder-Alkyl- oder C 5-7 -Cycloalkylrest oder einen ein di-(nieder-Alkyl)-substituiertes Stickstoffatom enthaltenden C 5-7 -Cycloalkylrest darstelit, verwendbar bei der Herstellung kolloidaler Lösungsmittelsysteme, werden ausgehend von den Verbindungen der Formel 1 analogen Verbindungen, worin Wasserstoff an Stelle einer der Reste R 1 , R 2 und R 3 vorliegt, hergestellt. Glycerin ether phosphatide of the formula wherein two of the radicals R 1 , R 2 and R 3 are C 10-30 alkyl radicals having at least 8 C atoms in a straight chain, at least one of these radicals being substituted by at least 2 C 1-3 alkyl radicals and the sum of the C -Atoms in both residues is greater than 20; and the third radical is a radical - P (O) (O - ) OR 4 , in which R 4 is a lower alkyl or C 5-7 cycloalkyl radical substituted by a quaternary ammonium group or a di- (lower alkyl) - Substituted nitrogen atom-containing C 5-7 cycloalkyl radical darstelit, usable in the production of colloidal solvent systems, are prepared starting from the compounds of formula 1 analogous compounds in which hydrogen is present instead of one of the radicals R 1 , R 2 and R 3 .
