摘要: Abstract The phase diagram of the system naphthalene/2-chloronaphthalene (N/CN) has been reexamined. previously reported solid solubility CN in N is erroneous. Crystals N/CN grown from melt were found to show very large radial inhomogeneity, with outermost few μm containing ca. 102 times bulk concentration. high concentration on surface appears result axial rejection impurity, followed by redistribution through sublimation.
