摘要:
Surfactants of the general formula R1—X where R1 is an aliphatic C17H35-alkyl radical and X is a hydrophilic group, and the mean degree of branching of the R1 radical is from 2.8 to 3.7. Mixtures which comprise such surfactants and the use of such surfactants and of mixtures thereof for tertiary mineral oil extraction.
