Abstract
ABSTRACT
Efficient solvent free green glycolysis for Polyethylene Terephthalate plastic waste, in this respect, PET waste was subjected to depolymerization process with trimethylene glycol (1,3-propandiol) in the presence of manganese acetate as trans esterification catalyst, the product is Bis-(3-hydroxy-propyl)-terephthalate, BHPT, as a non-ionic surfactant was separated and characterized by FT-IR and 1HNMR, The surface properties were studied by measuring the surface tension at different concentrations and temperatures. The surface tension, critical micelle concentration (CMC), and surface activities were determined. The surface parameters such as surface excess concentration (rmax), the area per molecule at interface (Amin)and the effectiveness of surface tension reduction ( πCMC ) were determined from the adsorption isotherms of the prepared surfactant. The thermodynamic data for the micellization and adsorption process were calculated and discussed.
