This paper described a crystallization procedure of the “1-Octadecanol/n-Nonadecane” binary system, an accurate description of the phase change process and the associated analysis of the cooling and melting of this binary system between 20°C and 70°C. The introduction section mainly describes the scientific background and principle of plant cuticle wax layer and the former studies on the crystallization of n-Alkanes and n-Alkanols. The experiment part introduces the experimental chemicals, instruments and specific experimental operating procedures required for the preparation of the “1-Octadecanol/n-Nonadecane” binary system. In the following sections, the thermal properties of this binary system are studied. According to the DSC diagram, phase diagrams and absorption spectrum, the specific phase transition and enthalpy of each phase transition were studied. The cooling and heating phase diagrams were plotted. The influence of the different compositions of these two chemicals was analyzed and discussed. The last part is the conclusion of this thesis, which summarizes the experimental research results of the complete text and points out the needed further research.
