Surfactants réactifs -- SynthèseIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : A series of novel anionic fumaric polymerizable surfactants with different lengths of carbon chains (C8–C14) were synthesized. The chemical structure of the surfactants was confirmed by 1H NMR, IR and MS. The values of critical micellar concentration (cmc) and gamma-cmc of the surfactants were determined. The surface properties of this series of designed polymerizable surfactants show their potential application in the emulsion polymerization to improve the stability of the latices and water sensitivity of the films.

SurfactantsIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Surfactants are widely used in the leather-making processes. The structure and property of surfactant obviously affect the quality and performance of leather. In this paper, a novel anionic surfactant, organosilicone modified sodium sulfonate of alkanolamide succinic acid monoester with palm oil was synthesized. Firstly palm oil was amidated with diethanolamine, then grafted with hydroxy-terminated silicone oil, esterified with maleic anhydride and sulphited with sodium bisulfite in sequence. The emulsification properties and fatliquoring performance of the prepared surfactant were tested. The influence of the mass percentage of reactants, the reaction temperature and time on the surface tension, the emulsifying activity and stability of the prepared surfactant were investigated. The FT-IR spectra analysis showed that under optimised conditions the novel surfactant was obtained. The fatliquoring application experiments showed that the novel surfactant is an excellent leather fatliquor.

ZwitterionsUn zwitterion (de l'allemand Zwitter — "hybride", "hermaphrodite » prononcé [tÍœsvɪtÉ›rjɔ̃]) est une espèce chimique moléculaire possédant des charges électriques formelles d’une unité, de signes opposés et situées en général sur des atomes non adjacents (dans le cas où les deux charges formelles sont portées par deux atomes adjacents, on parle d'ylures comme les ylures de phosphore). Les acides aminés, qui possèdent des groupements amine (sous forme d'ammonium NH3+ à pH =7) et acide carboxylique (sous forme de carboxylate COO- à pH =7) peuvent exister sous forme zwitterionique (à l'état solide, dans certaines gammes de pH en solution aqueuse) . Les bétaïnes sont d'autres exemples de zwitterions.Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Fourteen new sulfobetaines with N-alkylmorpholinium moiety have been synthesized using correspording N-alkylmorpholines and propanesultone or butanesultone. Their interfacial activities in aqueous solution were studied by equilibrium and dynamic surface tension measurements. Surface tension measurements provide information about the surface excess concentration, the minimum area per surfactant molecule, the critical micellar concentration (CMC) and the standard Gibbs energy of adsorption. The adsorption properties of these compounds significantly depend on the length of alkyl chain (the number of carbons). The lowest value of critical micellar concentration is obtained for the compound with the longest carbon chain and decrease with increasing of chain length of compounds considered. The same tendency is observed for effectiveness of adsorption. Note de contenu : - EXPERIMENTAL PROCEDURES

Surfactants -- SynthèseTags : 'Surfactants gemini' Imidazole 'Propriétés interfaciales' Synthèse Nanomatériaux Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Two novel imidazoline gemini surfactants quaternary ammonium salts of di(2-undecyl (heptadecyl)-1-formyl aminoethyl imidazoline) hexanediamine (SUAEIHDI/SHAEIHDI) were synthesized in this article, and their interfacial properties were studied. It was found that SUAEIHDI had a higher CMC value than SHAEIHDI in distillated water at constant temperature (12 ± 2) °C, indicating that it was easier for SHAEIHDI to form micelles in water. The symmetrical molecular structure of SUAEIHDI/SHAEIHDI is composed of lipophilic group and hydrophilic group comprising many active elements i.e. O, N and two imidazoline rings. The novel imidazoline gemini surfactants can be viewed as block-like copolymers, whose surface-modifying effects on nanomaterials are promising.
