Methodology:
The synthetic method was used. A Reichert microscope, type RCH, with a heating stage was used. A 26 x 38 mm slide was adapted to hold capillaries on the stage. Two glass strips were glued, using water glass, to the slide, leaving a 0.5 mm channel. The slide was then placed in the adjustable device of the heating stage. (1) and (2) were put into capillary tubing (0.2 to 0.3 mm diameters) by dipping consecutively into both liquids. The height of the liquid was 7 to 10 mm. Room temperature solids were melted on a glass slide over a micro burner. The capillary was sealed at both ends to a length of 30 to 35 mm, then inserted in to the channel on the slide and heated on the stage. The UCST was determined by following the appearance and disappearance of the meniscus.
