The phase relationships for all mixtures of biphenyl, naphthalene, phenanthrene, ortho-terphenyl, metaterphenyl, and monoisopropylbiphenyl were examined to determine what mixture constitutes and optimum organic coolant. The ten binary and ten ternary melting point diagrams for the flve unsubstituted compounds under consideration were determined experimentally. The vapor composition diagrams were also calculated for all of these mixtures. Some data were also obtained for the four and five component systems. Although some of the purely aromatic mixtures were liquid at 25 deg C or less, none of them satisfied the optimum coolant criteria with regard to the composition of the vapor phase. A ternary mixture of monoisopropylbiphenyl, ortho-terphenyl, and meta-terphenyl was found to satisfy all the criteria for an optimum organic coolant. A quaternary optimum mixture contains 14 wt. % monoisopropybiphenyl, 54 wt.% D- terphenyl, 15.5 wt. % m-terphenyl, and 16.5 wt.% phenanthrene. (W.L.H.)
