Density and viscosity have a wide range of applications, and naphthalene data were extremely scarce, so it is necessary to measure its density and viscosity. According to the solubilities of naphthalene in toluene and xylene and the surrounding temperature , In this paper, the densities and viscosities of naphthalene + toluene and naphthalene + xylene mixtures have been measureed in K ~ K, naphthalene molality, respectively, in 0~,0~ mol/kg. There are many methods for measuring the density and viscosity , in this study ,I have measured the density of mixed solution with 25ml pyometer capillary temperature conditions in the determination。 the viscosity with intrinsic viscosity, constant temperature water bath to control temperature fluctuations 177。 K. For the density and viscosity of the two binary system, I have drawed a conclusion that when the molality increase, the density and viscosity increase 。 with the temperature increase, contrarily, the density and viscosity will decrease. Meanwhile I have calculated the relevance among analysis of density, viscosity , temperature and the position of the solution, also I have used VogelTammanFulcher (VTF) equation for correlation, and obtaind the equation parameters and ARD, SD values.
