Aminoalcohol based surfactants with reduced surface tension and the use thereof

摘要

Aminoalcohols are prepared by reaction of at least one secondary amine with at least one epoxide. Aminoalcohols (I) are prepared by reacton of at least one secondary amine of formula (1) with at least one epoxide of formula (2) and/or (3).
