Abstract

Phytosterols are minor constituents of vegetable oils, which are being removed in the vegetable oil refining process such as deodorization. Deodorizer distillate is obtained in deodorization process, which contains about 4–8% of phytosterols. In the present study the aim was to utilized vegetable oil refining byproducts into valuable specialty surfactants. Phytosterols were isolated from deodorizer distillate of soybean oil using two different methods. In the first method methyl ester of deodorizer distillate was prepared and phytosterols isolated by crystallization. In the second method calcium soap of deodorizer distillate was prepared and unsaponifiable matter extracted using solvent. Phytosterols were isolated by crystallization in hexane from unsaponifiable matter. The phytosterols thus obtained was used for synthesis of sulfosuccinate surfactant. Surface active properties of phytosterols sulfosuccinate were evaluated and shows good surface active properties.

Kurzfassung

Phytosterole sind geringfügige Bestandteile von Pflanzenölen, die bei der Raffination von Pflanzenölen, wie zum Beispiel der Desodorierung, abgezogen werden. Das durch Desodorierung gewonnene Desodorierungsdestillat enthält 4–8% an Phytosterolen. Das Ziel der vorliegenden Untersuchung war, die Raffinationsnebenprodukte von Pflanzenöl als nützliche Spezialtenside zu verwenden. Die Phytosterole wurden nach zwei verschiedenen Methoden aus dem Desodorierungsdestillat von Sojabohnenöl isoliert. Nach der ersten Methode wurde das Desodorierungsdestillat mit Methylester aufbereitet und die Phytosterole durch Kristallisation isoliert. Nach der zweiten Methode wurde das Desodorierungsdestillat mit Kalziumseife aufbereitet, mit einem nicht verseifbaren Lösungsmittel extrahiert und durch Kristallisation in Hexan vom nicht verseifbaren Stoff isoliert. Die so erhaltenen Phytosterole wurden zur Synthese von Sulfosuccinat-Tensiden verwendet. Die oberflächenaktiven Eigenschaften dieser Phytosterol-Sulfosuccinate wurden als gut bewertet.
