Influencia de la temperatura en la formación de micelas de dodecilsulfato sódico y nonilfenol etoxilenado con diferentes grados de etoxilación

Main Article Content

This paper is a contribution to the physico-chemical study of the formation of mixed micelles at different temperatures in a mix of sodium dodecylsulphate with non-ionic surfactants of nonylphenol oxyethylate at 5, 10, 15, 20 and 30 m.O.E at different temperatures. Variation of the micellar concentrations was obtained at 25°C, 35°C and 45°C from surface tension results for different mixtures, which were studied at each temperature as a function of the proportion of mixture and the length of the oxyethylate chain. Each mixture was characterised by an empirical parameter that provided a quantitative index of the molecular interaction of the mixed micelles and the synergetic effect of the reaction.
