Abstract
Abstract (1) The lowerings of the congruent melting points of the alcoholates: LiCl·3CH3OH, LiCl·3CH3OH, LiCL·4C2H5OH, LiBr·4C2H5OH, and LiBr·4n-C3H7OH by the addition of foreign substances have been measured and the molecular depressions referred to 100 g. of each alcohol have been determined. (2) From these cryoscopic constants the heats of fusion of the alcoholates have been calculated. (3) When homologues of the solvent alcohol have been used as solutes, abnormally low values have been obtained for the cryoscopic constant. This discrepancy may be considered as due to the formation of a solid solution between the alcoholate and the solute alcohol and this fact has been semi-quantitatively verified.
