Abstract
The determination of dimethyl phthalate (DMP) that leached from twenty-four brands of plastic bottles in Thailand revealed the environment, conditions such as storage temperature, acid solution and chloride solution leads to the degradation process of PET polymer and phthalate compounds molecules could migrate from the inner surface area of a PET bottle, in contact with food into the food itself. The thermal degradation process of PET polymer occurred when temperatures increased and led to higher dimethyl phthalate leaching into the PET bottle. Moreover, the increasing of storage temperature could enhance the hydrolytic degradation process of PET polymer, leading to an increase in the dimethyl phthalate leached from the PET bottle at higher temperatures. In addition, High Performance Liquid Chromatography (HPLC) analysis could detect the peak of dimethyl phthalate that leaching from PET bottles when increased storage duration time and concentration of NaCl solution at temperature 600C Keywords- Polyethylene terephthalate (PET), Dimethyl phthalate (DMP), Degradation.
