摘要
The saturated vapor pressure data of 2-nitrotoluene, 3-nitrotoluene, and 4-nitrotoluene have been measured by comparative ebulliometry over the approximate range 380-460 K with estimated accuracy better than +/-0.01 K in the temperature and better than +/-0.05 % of the measured pressure value. The results obtained were represented by the Antoine equation. No accurate vapor pressures for 2-nitrotoluene and 3-nitrotoluene have been found in the open literature. For 4-nitrotoluene, the present data supplement the vapor pressures reported by Ambrose and Gundry (1980), both sets being in good mutual agreement. The joint vapor pressure data for 4-nitrotoluene were fitted by the Wagner equation, covering the entire range of conditions of the liquid-phase existence.
