ABSTRACT

Experimental vapor pressures, vaporization, fusion and sublimation enthalpies of a number of dialkyl benzenedicarboxylates have been examined by correlation gas chromatography (CGC) experiments in order to identify a series of experimental measurements that appear to be internally self-consistent. The compounds studied in this regard include dimethyl phthalate dimethyl terephthalate, dimethyl isophthalate, diethyl phthalate, dibutyl phthalate, and bis(2-ethylhexyl) phthalate. New vaporization enthalpies and liquid vapor pressure equations (T/K = 298.15 to 550) of several other compounds are reported also evaluated by CGC experiments. The compounds, the vaporization, fusion, and sublimation enthalpies and liquid and solid vapor pressures evaluated are summarized in Table 22 of the text.
