Abstract

Ten components of NaNSF were separated by thin layer chromatography (TLC) by using F254 silica gel plates as fixed phase and acidic alcohol solution as mobile phase. Adsorption of naphthalene sulphonate formaldehyde (NaNSF) on titania surface was studied through fundamental principles of surface physical chemistry, and the saturation adsorption of NaNSF was found to be much lower than that of dispersant in disperse dyes. This study is of reference significance to the investigation of mechanism of adsorption of dispersant on dyes, cement, and so on.

Kurzfassung

Ein Gemisch von zehn homologen Natriumnaphthalinsulfonat-Formaldehyd-Kondensationsprodukten (NaNSF) wurde dünnschichtchromatographisch unter Verwendung von F-254 Silikagelplatten als stationäre und einer sauren Alkohollösung als mobile Phase in die Einzelverbindungen getrennt. Es wurde eine physikalisch chemische Untersuchung der Adsorption der Naphthalinsulfonat-Formaldehyd-Kondensationsprodukte an Titandioxid-Oberflächen durchgeführt. Dabei wurde gefunden, dass die Sättigungsadsorption der NaNSF-Verbindungen deutlich niedriger ist als die von gebräuchlichen Dispergenzien in Farbpigment-Dispersionen. Die Untersuchung ist von Bedeutung für das Studium des Mechanismus der Adsorption von Dispergenzien an Farbpigmenten, Zement und anderen Feststoffen.
