Phasendiagramme und Exzeßvolumina der Systeme (CH3)2SiCl2/Pyridin und (CH3)2CCl2/Pyridin / Phase Diagrams and Excess Volumes of the Systems (CH3)2SiCl2/Pyridine and (CH3)2CCl2/Pyridine

Abstract

Abstract The isobaric melting and boiling diagrams for the systems: dimethyldichlorosilane/pyridine and 2,2-dichloropropane/pyridine are reproduced. The existence of the incongruently melting addition compounds (CH3)2SiCl2 · (Pyridine)2 and [(CH3)2CCl2]3 · Pyridine could be proved. Some measurements of the molar volume of mixtures of pyridine and dimethyldichlorosilane, and pyridine and 2,2-dichloropropane are reported. For both systems the molar excess volume has been calculated as a function of the mole fractions.
