Surface and Thermodynamic Characterizations and Secondary Transition of Novel Phthalocyanine Glass

Abstract

The novel 4-(3-tert-butyl-4-hydroxyanisole)]phthalonitrile and its peripherally tetra substituted zinc phthalocyanine complex [2,9(10),16(17),23(24)-tetrakis(4-(3-tert-butyl-4-hydroxyanisole) phthalocyaninato]zinc(II) (ZnPc) were synthesized and characterized by elemental and spectroscopic analysis techniques. The inverse gas chromatography (IGC) method was used to obtain secondary transition, surface properties, and thermodynamic interaction parameters of the phthalocyanine glass. Phthalocyanine selectivity was investigated using the acetate and alcohol isomers by IGC method at temperatures between 313.2 and 423.2 K. The secondary transition temperature was obtained by IGC method and differential scanning calorimetry (DSC). The dispersive component of the surface free energy, γSD, of adsorbent surface was calculated in the infinite dilution region. The specific enthalpy of adsorption, ΔHAS, the specific free energy of adsorption, ΔGAS and the specific entropy of adsorption, ΔSAS of solvents on ZnPc were ...
