Abstract
The structures of molecular aggregates in monostearoylglycerol- water systems were determined primarily by small angle X-ray diffraction method. Based on the results, the phase diagram in these systems were constructed.<BR>Some crystal phases and a gel phase were shown to exist at temperature below Tc. The phase transition between crystals was observed at about 17°C and two crystals phases were shown to exist above 17°C. The layer spaces of the crystals differed. The crystals were α and β forms according to wide angle X-ray diffraction. The a crystal was transformed to the β crystal with respect to time.<BR>A reversed hexagonal phase was present in the region of high monoacylglycerol concentration at higher temperature than Tc. On the contrary, a lamellar phase was found at low concentration range. The lamellar phase was transformed into two different cubic phases at temperature exceeding 70°C. The cubic phase (C1) was present in more than 60 wt% of the monostearoylglycerol. The other cubic phase (C2) existed at monostearoylglycerol content below 60wt%. The size of the liquid crystals were determined in part by temperature.<BR>With formation of the liquid crystals, it became apparent that their structures were determined primarily by the quantity of hydrated water and molecular geometry.
