  Surface properties of new catanionic semi-fluorinated hybrid surfactants

  摘要：

  In order to study their aggregation behaviour, a rapid synthetic procedure from perfluoroalkylethyl thiol derivatives led to twenty four original catanionic hybrid surfactants of general formula: [RF(CH2)(2)S(CHQ)(2)CO2-; HN+(CH3)(2)R-H (Q= H or Cl; R-F = C4F9, C6F13, C8F17; R-H = C6H13, C8H17, C10H21, C12H25)]. Critical aggregation concentration (CAC), surface tension at the CAC (gamma s) and free energy of aggregation (Delta G(A)degrees) of the title surfactants, in aqueous solution, have been investigated as a function of the number of carbon atoms in both the fluorinated and the hydrocarbon tails. TEM studies were used to estimate the shape and size of the aggregates and confirmed the general tendency of fluorinated surfactants to form aggregates with lesser curvature. These catanionic surfactants exhibited very low surface tension at critical aggregation concentration (CAC) of 15.3-17.4 mN m(-1) as well as low CAC of 3 x 10(-5)-11 x 10(-3) and the substitution of one hydrogen atom by one chlorine atom didn't affect significantly the aggregation phenomenon.

• Synthese D'α-chloro (2-F-alkyl ethyl thio) acetates d'ethyle en vue de l'obtention de precurseurs de tensio-actifs bicaudaux F-alkyles

  In this work we report the synthesis of ethyl alpha-chloro (F-alkyl-2 ethyl thio)acetates (F-alkyl: C4F9-,C6F13-,C8F17-) which are potential synthetic intermediates. We investigated their reactivity with mercaptans and alcohols: the dithioacetal compounds are excellent precursors in the synthesis of double-tailed amphiphiles (25 new compounds were obtained, identified and described).
