Study on the Sublimatographic Characters of Sulfur

황의 Sublimatographic Characters에 관한 연구

Sublimatographic study on the method of test for sulfur in the petroleum and rubber products was as following results: (1) The relation between the heating temperature$(t_h)$ and the vacuum condensing point(V.C.P.) of sulfur at different degree of vacuum appeared as Fig.4. The results were in good agreement with those expected from the $t_h-V.C.P$ curves of sublimatographic separation of sulfur. (2) The relation between the degree of vacuum and the V.C.P. at different heating temperature of sulfur appeared as follows; $$tv.c.p.=\alpha+{\beta}logP_{va}$$ (3) The V.C.P of sulfur could be physical property comparing with melting point and boiling point. (4) The relation between the V.C.P. and the quantity of sublimation of sulfur becomes quantitative as Fig.7.
