Abstract
Herein, glycolysis reaction was performed for managing of disposed polyethylene terephthalate (PET) using various molecular weight grades of polyethylene glycol. The glycolyzed-PET intermediates were converted into their active bromide derivatives throughout the interaction by bromoacetic acid. The active bromide derivatives were reacted by pyridine to yield the cationic bromide compounds. Assemblies of the finally produced compounds were chemically recognized by spectroscopic determination (FTIR, 1H NMR). The glycolyzed PET compounds functionalized by cationic quaternary groups were assessed for their anticorrosive properties and the protection of pipelines in oilfields against deterioration. The composites were assessed at different concentrations in a simulant medium of the oil wells (0.5 M H2SO4). Furthermore, the bacterial potencies of the organized composites were assessed in contradiction of diverse bacteria's strains using minimum inhibition concentration (MIC) evaluation. The results of mass decline and electro-chemical evaluations on carbon steel revealed that the products are exhibited excellent anticorrosive and antimicrobial efficiencies.
