Abstract

A series of ethoxylated sodium monoalkyl sulfosuccinate (ESMASS) ester surfactants were prepared by reaction of polyethylene glycol (M. wt. 600) with sodium mono alkyl sulfosuccinate (SMASS). The esters were prepared by reaction of octyl, lauryl or cetyl alcohol with sodium sulfosuccinate (SSS) to prepare E(14)SMOSS, E(14)SMLSS and E(14)SMCSS. The chemical structures of the prepared surfactants were confirmed by FTIR and 1HNMR spectroscopy. The surface tension of the synthesized surfactants was measured at 25°C individually or mixing at different molar fraction with the sodium dioctyl sulfosuccinate. The surface active properties were calculated and micellization process of the mixture was investigated. The molar ratio of anionic (SDOSS) and anionic-nonionic surfactants moiety [E(14)SMOSS, E(14)SMLSS and E(14)SMCSS] in the mixed aggregates were deduced using the regular solution approximation equations. Depending on the critical micelle concentration values for each surfactant individually and mixed systems, the minimum surface tension was exhibited at mixture of [0.6 SDOSS and 0.4 E(14)SMCSS]. The micellar composition of the mixed aggregates were explained and discussed based on the effect of their chemical structures. Activity coefficient (f1, f2), interaction parameter (b) and ideality of anionic-nonionic mixed aggregates were evaluated.

Kurzfassung

Eine Reihe von Tensiden aus ethoxylierten Natriummonoalkylsulfosuccinatestern wurde durch Reaktion von Polyethylenglykol (M. wt. 600) mit ethoxyliertem Natriummonoalkylsulfosuccinat (SMASS) dargestellt. Die Ester wurden durch Reaktion von Octyl-, Lauryl-, oder Cetylalkohol mit Natriumsulfosuccinat (SSS) dargestellt, um E(14)SMOSS, E(14)SMLSS and E(14)SMCSS zu bilden. Die chemische Struktur der dargestellten Tenside wurde mittels FTIR und 1HNMR Spektroskopie bestätigt. Die Oberflächenspannungen der synthetisierten Tenside wurden bei 25°C einzeln oder gemischt bei verschiedenen molaren Anteilen mit Natriumdioctylsulfosuccinat gemessen. Die Eigenschaften der Oberflächenaktivität wurden berechnet und der Mizellisierungsprozess der Mischungen untersucht. Das molare Verhältnis von anionischen (SDOSS) und anionisch-nichtionischen Tensidgruppen [E(14)SMOSS, E(14)SMLSS und E(14)SMCSS] in den Mischaggregaten wurde durch Annäherungsgleichungen regulärer Lösungen abgeleitet. Abhängig von den Werten der kritischen Mizellbildungskonzentration für jedes einzelne Tensid und deren Mischsysteme, zeigte sich das Minimum der Oberflächenspannung bei Mischungen von [0.6 SDOSS und 0.4 E(14)SMCSS]. Die mizellare Zusammensetzung der Mischaggregate wird erklärt und auf Basis ihrer chemischen Struktureffekte diskutiert. Die Aktivitätskoeffizienten (f1, f2), der Wechselwirkungsparameter (b) und der ideale Zustand der anionisch-nichtionischen Mischaggregate werden bewertet.
