STRUCTURAL EVOLUTION AS A FUNCTION OF TEMPERATURE FOR THE MIXTURES N-DOCOSAN N-TETRACOSAN FOR VARIOUS CONCENTRATIONS BETWEEN 20 AND 48 MOL PERCENT IN N-TETRACOSAN - SOLID-LIQUID EQUILIBRIUM DIAGRAM OF THE SYSTEM N-C22-N-C24

Phase transitions was determined as a function of the temperature by X-Ray analysis for various concentrations of n-docosan and n-tetracosan between 20 and 48 mol percent n-tetracosan. The mixtures presenting the orthorhombic structure beta" transform to the orthorhombic structure beta without any intermediate phase transition beta'. These investigations together with the others results obtained in the binary system: n-docosan-n-tetracosan made possible establishing the solid liquid equilibrium diagram.
