SYNTHESIS 3-[2F-ALKYLETHYLAMINO]-1,2-EPOXYPROPANES AND PREPARATION OF NEW MONOTAILED AND BITAILED SURFACTANTS WITH BETA-HYDROXYL GROUP

In this paper we report the synthesis of new intermediates of the type 3-[2-F-alkyl-ethylamino]-1,2-epoxypropanes which lead simply and with good yields to a large range of fluorinated monotailed, bitailed and hydrogenated/fluorinated bitailed surfactants having a secondary amino group and at least one hydroxy group. Evaluation of their surface properties has allowed the contribution of each hydrophobic tail contained in the hydrogenated and fluorinated bitailed molecules to be demonstrated.
