Abstract

Design and synthesis of a new galactolipid 6 with carbamate was described in this work. Compounds 1–3 were obtained easily with classical synthesis methods which were improved a little. The influence of the solvent and different groups of the tertiary amine 4 for the quaternization reaction was discussed. The mixture of chloroform, ammonia and methanol was used well as the elution for separating compound 5 with silica gel column chromatograph. The CMC and γCMC was 2.40 · 10−4 mol/L and 26.1 mN m−1, respectively by surface tension measurement. Vesicles can be formed according to the theory of critical packing parameter since the value of the critical packing parameter was 0.83 at CMC, and it was confirmed by TEM micrograph.

Kurzfassung

In dieser Arbeit wurde die Herstellung eines neuen Galactolipids 6 mit Carbamat beschrieben. Die Verbindungen 1–3 wurden einfach mittels klassischer, geringfügig verbesserter Synthesemethoden erhalten. Der Einfluss des Lösemittels und der verschiedenen Gruppen des tertiären Amins 4 in der Quaternisierungsreaktion wurde diskutiert. Die Mischung aus Chloroform, Ammoniak und Methanol war ein gutes Elutionsmittel für die chromatographische Trennung der Verbindung 5 in der Silicagel-Säule. Die kritische Mizellbildungskonzentration CMC beträgt 2,40 · 10−4 mol/L und die Oberflächenspannung 26,1 mN m−1. Vesikel wurden entsprechend der Theorie der kritischen Packungsparameter gebildet. Der Wert des kritischen Packungsparameters bei der CMC ist 0,83. Dies konnte mit TEM-Mikroskopie bestätigt werden.
