Résumé : |
Sulfosuccinate type anionic surfactants are classical ingredients for industrial applications. They are of great interest because of their excellent surfactant properties. Fatliquors prepared from sulfosuccinates have been effectively utilized in the leather industry, where the degree of sulfonation of the surfactant plays a crucial role in deciding performance. This paper reports on the study of factors such as the addition of phase transfer catalyst, non-ionic wetting emulsifier and co-solvent on the degree of sulfonation. Emusification power, zeta potential, surface tension and particle size were measured. Reaction conditions were optimized, based on the results. Fatliquors were prepared using different sulfosuccinates and applied on leather. The properties of resultant leathers were studied qualitatively and quantitatively, and SEM studies were carried out for the treated leathers. This work provides a basis for the development of better fatliquoring agents. |
