| Abstract: | An experimental apparatus was established for determining very low vapor pressures by using the Knudsen weighing effusion method. The reliability of the apparatus was checked by measuring the low vapor pressures of n-hexadecane. Vapor pressures of 7 substances including n- octadecane, 1-octadecene, diethylphthalate, dimethylterephthalate, di-isopropylnaphthalene, dicyclohexylphthalate and pyrene were determined at temperatures from 298 to 373 K and correlated by the Antoine equation. |
