摘要：
Solubility curves (liquidus) of some aromatic amines in naphthalene were determined. Removing the amines from coal tar naphthalene by fractional mass crystallization was studied. The role of individual process stages in the course of naphthalene purification was discussed. The results of laboratory studies were confirmed by the pilot plant test.
