Determination of Melting Point of Succinonitrile–Pyrene System by Capillary Method (CAT#: STEM-PPA-0045-YJL)

Introduction

The vast field of materials, both natural and man-made, exhibits the intimate interdependence between society and nature. Many aspects of science and engineering are directed presently to the understanding and utility of materials with respect to performance, reliability and cost. Recent advanced technologies rely on sophisticated advanced materials. Most of these materials are mixtures of one or more phases. In a material, the presence of one or more phases causes interaction between them due to which the resulting properties are usually different from the properties of the individual phases.
An organic analogue of a metal–nonmetal system, namely, succinonitrile (SCN)–pyrene (PY), where SCN and PY have their heat of fusion values 3.7 and 16.6 kJ mol−1, respectively was chosen. Purity of both the components was checked by determining the melting point and comparing its value with that in the literature.
