THERMAL-CONDUCTIVITY OF THE MOLECULAR-CRYSTAL (-)2-(ALPHA-METHYLBENZYLAMINO)-5-NITROPYRIDINE

Thermal diffusivities of high quality (-)2-(alpha-methylbenzylamino)-5-nitropyridine (MBANP) single crystals were measured in different directions by the flash diffusivity method. The complete thermal conductivity tensor at temperatures of 295, 323, and 349 K was then obtained for this monoclinic crystal from the thermal diffusivity, specific heat, and density data. For instance, the thermal conductivity coefficients at 295 K are k1=0.27 W/mK, k2=0.29 W/mK, and k3=0.20 W/mK. The peak melting point of MBANP lies at 357.3 K, whereas the corresponding enthalpy of melting DELTAH(m) has a value 67.2 J/g.
