Abstract

N,N-bis-(2-hydroxyethyl)oleamide (NHEO) was synthesized using oleic acid and diethanolamine in 1:1 molar ratio using orthophosphoric acid as catalyst. The reaction kinetics at 140°C has been evaluated. The latter follows a first order reaction rate which is in accordance with the reaction mechanism proposed. Yield optimization has been performed implementing an L4 Taguchi orthogonal array. The chemical analysis, rheological behavior and stabilizing ability of the product for metal and metal oxide slurries has been investigated.

Kurzfassung

Aus Ölsäure und Diethanolamin im molaren Verhältnis von 1:1 wurde mit Orthophosphorsäure als Katalysator N,N-Bis-(2-Hydroxyethyl)oleamid (NHEO) dargestellt und die Reaktionskinetik bei 140°C bewertet. Letztere folgt einer Reaktionsgeschwindigkeit erster Ordnung, die mit dem beabsichtigten Reaktionsmechanismus übereinstimmt. Die Optimierung der Ausbeute wurde mittels einer L4 Taguchi Orthogonal Array Methode ausgeführt. Die chemische Analyse, das Rheologieverhalten und Stabilisierungsvermögen des Produktes für Metall- und Metalloxidschlämme wurde untersucht.
