|Title:||Polymorphism in Solid 1,1,1-trichloroethane and Solid 2,2-dichloropropane|
|Advisor:||Morrison, J. A.|
|Abstract:||<p>The methylchloromethane (MCM) compounds ((CH₃) in C Cl(n-4) with 0</p> <p>2,2-dichloropropane has three solid phases and only one is cubic. The cubic phase is unusually stable; this may be attributable to a stabilizing influence of the surface (glass) of the sample cell. The optical birefringence results give a different view of the transitions than that deduced from existing meagre thermal data.</p> <p>The information gleaned from the optical birefringence measurements had subsequently led to an extensive investigation of the thermal properties of 1,1,1-trichloroethane with a high precision adiabatic calorimeter. It has confirmed the general description of the interrelation between the different phases given here as well as the strategic role played by impurities.</p>|
