UN PROCEDIMIENTO PARA LA PREPARACION DE FOSFATIDOS DE ETER DE GLICOL

摘要

Compounds of the general formula I wherein two of the residues R1, R2 and R3 represent C10-30-alkyl residues with at least 8 C-atoms in a straight chain, at least one of these residues being substituted by at least 2 C1-3-alkyl residues and the sum of the C-atoms in the two residues being greater than 20; and the third residue is a residue -P(O)(O-)OR4 in which R4 represents a lower-alkyl or C5-7-cycloalkyl residue which is substituted by a quaternary ammonium group or a C5-7-cycloalkyl residue which contains a di-(lower-alkyl)-substituted nitrogen atom, are useful for the manufacture of colloidal solution systems. The compounds of formula I can be prepared starting from glycerol derivatives as described in more detail in the specification.
