Abstract
In the present investigation, a series of alkyl polyglycosides with alkyl chain length of C 8, 9, 10, 12 and 14 were synthesized using transacetalization method. Purity of the products was investigated using high performance liquid chromatography. Surface parameters particularly Effectiveness πcmc, Efficiency Pc20, maximum surface excess Γmax, minimum surface area Amin and HLB values are investigated, in addition to thermodynamic parameters (ΔGads and ΔGmic). Resistance to hydrolysis for the prepared compounds was investigated. The synthesized compounds were tested for their biodegradability in Nile river water according to Die-away test method and their antimicrobial activity against different strains of bacteria, yeast and fungi was investigated.
Kurzfassung
In der vorliegenden Arbeit wurde eine Reihe von Alkylpolyglycosiden mit einer Alkylkettenlänge von C 8, 9, 10, 12 und 14 mittels Umacetalisierung synthetisiert. Die Reinheit der Produkte wurde mittels Hochdruckflüssigkeitschromatographie untersucht. Zusätzlich zu den thermodynamischen Parametern (ΔGads and ΔGmic) wurden die Oberflächenparmeter, insbesondere die Effektivität (πcmc), die Adsorptionswirkung (Pc20), die Oberflächenüberschusskonzentration Γmax, die Minimumoberfläche Amin und die HLB-Werte sowie die Beständigkeit gegen Hydrolyse untersucht. Die synthetisierten Verbindungen wurden entsprechend der Die-away Testmethode auf ihre biologische Abbaubarkeit in Nilwasser und auf ihre antimikrobielle Aktivität gegen verschiedene Bakterienstämme, Hefe und Pilze untersucht.
