| 摘要 |
The present invention relates to compounds of the formula I <IMG> (I) in which R1 is hydrogen, a substituted or unsubstituted aliphatic radical having up to 30 carbon atoms, a substituted or unsubstituted alicyclic radical having up to 30 carbon atoms, a substituted or unsubstituted aromatic radical having up to 24 carbon atoms or a substituted or unsubstituted heteroaromatic radical having up to 20 carbon atoms, R x' = 0 - 80, y' = 0 - 50, x'' = 0 - 80 and y'' = 0 - 50, with at least one of the variables x', y', x'' and y'' being greater than 0. The compounds of the formula I are prepared by reacting the corresponding dihydrogen phosphate with the respective amino acid or salt thereof. The compounds according to the invention can be employed, for example, as surfactants for emulsifying organic solvents in water.
