Abstract

Illegal discharge of waste cooking oil (WCO) not only causes environmental pollution but also wastes useful resources. Converting WCO into surfactant to partially substitute virgin vegetable oil is one of the measures for solving simultaneously the three problems of food security, pollution, and raw materials shortage. In this paper, the pretreatment of WCO was investigated, WCO and purified WCO were analyzed, purified WCO was used as an alternate feedstock for surfactant preparation by a chemical three-step modification process, structure characterization and surfactivities of obtained surfactant were demonstrated.

Kurzfassung

Die illegale Entsorgung von Speiseöl (WCO) verursacht nicht nur Umweltbelastungen, sondern verschwendet auch nützliche Ressourcen. Die Umwandlung von WCO in Tensid, um teilweise reines Pflanzenöl zu ersetzen, ist eine der Maßnahmen, um gleichzeitig die drei Probleme der Ernährungssicherheit, der Verschmutzung und der Rohstoffknappheit zu lösen. In dieser Arbeit wurde die Vorbehandlung von WCO untersucht, WCO und gereinigtes WCO analysiert, gereinigtes WCO als alternatives Einsatzmaterial für die Tensidherstellung durch ein chemisches Modifikationsverfahren in drei Schritten verwendet. Die Strukturcharakterisierung und die Oberflächenaktivitäten des erhaltenen Tensids wurden nachgewiesen.
