Methodology:
The synthetic method was used. Samples of (1) and (2) of weight about 0.2 g were placed in glass ampoules of length 3 to 4 cm and inner diameter of 4 mm. After cooling in a mixture of ice with salt ampoules were sealed. Three to four ampoules were attached to a thermometer and placed in a glass bath with glycerine (for heating) or with acetone and solid $\ce{CO2}$ (for cooling) with continuous stirring. The heating and cooling 2 K per minute. The UCST was determined by following the appearance and disappearance of the meniscus.
