ABSTRACT
Phase diagrams of naphthalen-2-ol + 1,3-dinitrobenzene have been investigated by the thaw melt method. The results show the formation of a simple eutectic mixture. Enthalpy of fusion values of pure components and the eutectic mixture were obtained from DSC studies. Linear velocity of solidification of pure components and the eutectic mixture was determined at different undercooling rates. The values of the linear velocity of crystallization indicate the nonideal nature of the eutectic mixture in the melt. The anisotropic and isotropic crystallizations of naphthalen-2-ol, 1,3-dinitrobenzene, and the eutectic mixture were studied. The flexural strengths of the pure components, hypo- and hypereutectics, and eutectic mixture were determined.
