Abstract
The glass-transition temperature (T g) in binary mixtures of the primary alkanols with CBr 4 and CHBr 3 has been measured as a function of composition. The results are compared with earlier studies on alkanol solutions of organic chlorides. The initial molar slope (IMS) of theT g vs. composition curve at the pure alkanol indicates formation of a 1:1 halide-alkanol complex stabilized by a specific halogen-oxygen interaction. The IMS values decrease in the order CBr 4 >CHBr 3 >CCl 4 >CHCl 3 >CH 2 Cl 2 , reflecting decreasing stability of the complex.
