萘—联苯—α-萘酚三元系相图的研究

STUDY ON PHASE DIAGRAM OF THE TERNARY SYSTEM NAPHTHALENE-BIPHENYL-α-NAPHTHOL

用目视变温法测定了题示三元系的相图。三元系为低共熔体系,低共熔点为32.8℃,38.3 mol%萘和48.3 mol%联苯。

A visual-polythermal method was used to study solid-liquid equilibria of the binary system NaSCN-NaNO_3 and the ternary system NaSCN-NaNO_3NaCI. Almost ideal ideal behavior was observed with the binary system, the eutectie occurs at 227℃ and 45.3mol% NaSCN. The ternary system is eutectie type, the eutectic at 223℃, 44.5mol% NaSCN and 52.9mol%NaNO_3.
