We thus obiain a specific heat C, p,7 , whichis finite a the erica point, via Eq 10 , below. Symbols and units are given i the st above, and the coexistence phase disgram is outlined in Fg.

Hence, some excluded data, sre presented inthis report, but ar used with zero weigh for the least-squares determination of the coefficients in fitting fumanain, Tae aclete vsial LOS fo Howadeusy sephoe also is presented below Ea, 4 ].
Apparentiy no high-pres- sure melting line P, 7 has been established for methanol, which forms passes under these conditions.
See, however, 8, Carlson and Westrum" for calorimetric transitions at low pressures and temperatures. Vapor Pressures Some ofthe available vapor-pressure data for methanol are listed in Table 2.
