Langues : Anglais (eng) Tags : Sodium salts fatty alcohol polyoxyethylene ether sulfonate isethionate Temperature tolerance Salt Interfacial tension Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Sodium salts of fatty alcohol polyoxyethylene ether sulfonates with different length of hydrophobic chain (CnE3SO3, n = 14, 16, 18) were synthesized from sodium isethionate, then the structure was verified by IR. The temperature resistance, calcium-tolerant stability and salt tolerance were evaluated by pyrogenetic decomposition, phase separation and middle phase emulsion respectively. In addition the mixture of CnE3SO3 and heavy alkylbenzene sulfonate (HABS) was studied. The results showed that : (1) CnE3SO3 was very stable at 150°C especially in neutral, weak acid and weak alkaline conditions ; (2) CnE3SO3 performed a good salt tolerance and have a rank of C18E3SO3 > C16 E3SO3 > C14E3SO3 ; (3) the calcium-tolerant stability of CnE3SO3 reached 8700 mg/L, 9500 mg/L and 10000 mg/L respectively ; (4) CnE3SO3 was very good for improving the salt tolerance of mixture of CnE3SO3 and HABS. C18E3SO3 was the best in mixtures of Daqing crude oil/water containing C18E3SO3 and HABS in a ratio of omega C18E3SO3):omega(HABS) = 3:7 and showed the strongest synergistic effect. The interfacial tension in the system Daqing crude oil/water reached a minimum in the order of 10–3 mN/m and was always below 10–2 mN/m for cNaCl from 0 to 15000 mg/L.

The results show that DLBS can be synthesized by reaction of industrial dodecyl benzene with lauroyl chloride in the presence of AlCl3, followed by sulfonation with ClSO3H and neutralization with NaOH. The lauroyl-group is confirmed to be connected to the para-position of the alkylbenzene by1HNMR spectrum. The synthesized DLBS is well soluble in pure water and reservoir (connate) water at 45 °C. It is highly surface active which is indicated by its low CMC of 1.1 · 10–5mol/L, and its low surface tension, γmc of 28.6 mN m–1. By mixing with heavy alkylbenzene sulfonates of relatively low average molar mass (387g mol–1) at a total surfactant concentration of 5 mM, DLBS can reduce the interfacial tension of Daqing crude oil/connate water to an order of 10–3mN/m at 45 °C in the presence of 0.5–1.0 wt.% NaOH and 1000 mg L–1of polymer. If the NaOH was replaced by a gentle alkaline salt, Na2CO3, certain amounts of dodecyl dimethyl carboxy betaine were added and the concentration of Na2CO3was increased to 1.2–2.0 wt.%, the interfacial tension of Daqing crude oil/connate water can also be reduced to an ultralow value. Therefore DLBS is a good hydrophobic surfactant applicable in ASP flooding with either NaOH or Na2CO3as alkaline agents.

Titre : A process for the production of Φ-sulfo fatty methyl ester sulfonates (Φ-MES) Type de document : texte imprimé Auteurs : L. Cohen, Auteur ; D. W. Roberts, Auteur ; C. Pratesi, Auteur Année de publication : 2010 Article en page(s) : p. 18-23 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Surfactant Sulfoxidation Φ-sulfo fatty methyl ester sulfonate Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Phi-Sulfo Fatty Methyl Esters sulfonates (phi-MES) were obtained via sulfoxidation of fatty acid methyl esters (FAME) with SO2, O2, and ultraviolet light of appropriate wavelength. Expectedly, these products may be used as linear alkylbenzene sulfonate (LAS) and alkyl ether sulfate (AES) partners, either in heavy-duty or in hand dishwashing liquids. Phi-MES are new anionic surfactants that can be regarded as potential components for detergent formulations and body care products as well. In this work we summarize the most relevant results of our research started fifteen years ago, on the synthesis, separation and analysis of phi-sulfo fatty methyl ester sulfonates known as phi-MES, and we update our last findings. We have to point out that we are for the time being, the only research group in the world to have published our research on phi-MES. This paper describes the optimum batch conditions for the sulfoxidation of FAME and a reaction mechanism is proposed. The paper depicts an improved workup for the separation of reaction products from non reacted methyl ester and the GC-MS analysis of phi-sulfo fatty methyl ester sulfonate is shown. Finally, an interpretation of conversion and selectivity of sulfoxydation reaction is given. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=8065
