This note reports the solidand liquld phase equilibria for mixtures of tetrachloromethane with nitrogen-containing com-pounds. The solid intermolecular compound forms in mixture of tetrachloromethane withbenzene, the intermolecular bonding in compound has been assumed to be charge transfer.The intermolecula compounds form easily in mixtures in which the electron density of thebenzene ring has been increased in the presence of electron-excluding substituents in展开更多

The second component in the three tetrachloromethane mixtures have cyclic structure. Ref. [2] pointed out that the cyclic structure of the second component is very important during the compound formation in展开更多
