Thermodynamic properties pertaining to phase equilibria in the binary‐fluid hydrate systems, methylene chloride‐water and chloroform‐water, and the ternary hydrate system, methylene chloride‐chloroform‐water, were measured. Total vapor pressure data were recorded as a function of temperature over a range of −3 to + 10°C. Quadruple locus measurements of the ternary four‐phase equilibrium, L 1 ‐ L 2 ‐ H ‐ G , and isobaric studies of the ternary system chloroform‐methylene chloride‐water, support the existence of a solid solution hydrate between methylene chloride and chloroform. The addition of the nonhydrate former, hexane, to the methylene chloride‐water system lowered the isobaric critical decomposition temperature of the hydrate.
