Abstract

Addition of electrolytes to surfactant solutions does change the temperature at which the clouding phenomena occur. Electrolytes have a large effect on the cloud point (CP) of hexa ethyleneglycol mono-n-dodecyl ether (C12 E6)/water system, because of their effect on water structure and their hydrophilicity. In this work we report the effect of electrolytes (KCl, NaCl and Na2CO3) on the (CP) of C12 E6/water system. It has been observed that the cloud point as a function of electrolyte's concentration, depends mostly on the electrolyte's charge. Furthermore it has been observed that the two factors, temperature and salt concentration mainly affect equivalently the phase separation of C12 E6/water system. Moreover, ionic surfactants such as sodium dodecyl sulfate (SDS) and carboxylate ethoxyle (TDC) have been used to investigate their effect on CP of C12 E6.

Kurzfassung

Die Zugabe von Elektrolyten zu Tensidlösungen verändert die Temperatur, bei welcher Trübungsphänomene auftreten. Aufgrund ihres Effektes auf die Wasserstruktur und ihrer Hydrophilie haben Elektrolyte einen großen Einfluss auf den Trübungspunkt eines Hexaethylen-glykolmono-n-dodecylether(C12 E6)/Wasser-Systems. In dieser Arbeit untersuchen wir den Einfluß von Elektrolyten (KCl, NaCl und Na2CO3) auf den Trübungspunkt eines C12 E6/Wasser-Systems. Es wurde beobachtet, dass der Trübungspunkt als Funktion der Elektrolytkonzentration hauptsächlich vom Elektrolyt-Anion abhängt. Außerdem konnten wir feststellen, dass hauptsächlich die zwei Faktoren Temperatur und Salzkonzentration, gleichermaßen die Phasentrennung des C12 E6/Wasser-Systems beeinflussen. Weiterhin wurde der Einfluss ionischer Tenside, wie z. B. Natriumdodecylsulfat und carboxyliertes Ethoxylat auf den Trübungspunkt von C12 E6 untersucht.

Moussa Alibrahim was born in 1955 and obtained his B.Sc. in the field of chemistry from Damascus university in 1979 and his Ph.D. in the field of Chemistry and molecular physical chemistry (France- Nancy university I, 1988). In 1980 he started working in the Syrian Atomic Energy Commission in chemistry department. He has been awarded to prepare his Ph.D. in France (Nancy university I) from 1982 to 1988, under the supervision of Prof. J. C. Ravey; Prof. C. Tondre; Prof. M. J. Stebe and J. J. Delpuech. His theses presented subject is [SYSTEMES A BASE DE TENSIOACTIFS NONIONIQUES: INFLUENCE DE CO-TENSIOACTIFS IONIQUES ET STRUCTURE DES PHASES MESOMORPHES]. He restarted working in the chemistry department of the Syrian Atomic Energy Commission again from 1989 until now, in the field of Physical Chemistry and Solvent Extraction.
