The relation between the heating temperature and the V.C.P(Vacuum Condensing Point) at different degree of vacuum through the sublimatographic separation was studied where by ; (1) Anthracene and Anthraquinone, ${\alpha}$-Naphtol and ${\beta}$-Naphthol, o-Aminobenzoicacid and p-Aminobeenzoicacid were easily separated from each of its mixtures as shown in Figure9, 10 and 11, while tailings appeared appreciably. The results were in good agreement with those expected from the $t_k$-V.C.P curves in Figures 3,4,5,6,7 and 8. (2) The relation between the degree of vacuum and the V.C.P. of ${\alpha}$-Naphthol and Anthracene at different heating temperatures appeared as follows and are shown in Figures 12 and 13.
