Polyethylene terephthalate waste (PET) was
depolymerized by thiodiglycol into thioglycolyzed product. The product was
characterized by FTIR and 1HNMR spectroscopy and the thermal
properties (TGA, DTA) showed that the prepared compound was thermally stable until
250°C. The efficiency of the prepared corrosion
inhibitor for carbon steel was measured by using acid media (0.1 HCl) as
corrosive environment and the inhibitor concentration was (0, 10, 20, 30, 40 and
50 ppm). The electrochemical technique used Tafel plot to measure the
efficiency of inhibitor. Factors effect on the rate of corrosion like temperature
(298, 308, 318, 328 K) and concentration (10, 20, 30, 40, 50 ppm) of inhibitor
were studied. From the obtained results many factors were calculated that
determined the efficiency of the inhibitor like corrosion rate, charge transfer
resistance and inhibitor efficiency. It was observed that the corrosion rate
and charge transfer of the carbon steel for the inhibitor increase with increase
of temperature and decrease with increase of the inhibitor concentration in the
same temperature. The results showed that the inhibitor had high inhibition in
reducing the corrosion rate. The inhibition efficiency (% IE) reached 97.1% for
the 40 ppm concentration at 308 K.
