Abstract

Stability of di(ethyl hexyl) adipate (DEHA), diisobutyl  adipate(DIBA), dibutyl adipate (DBA), di(ethyl hexyl) sebacate (DEHS) and dibutyl sebacate (DBS) in the three aqueous food simulants:  distilled water, 3%w/v acetic acid and 10%v/v ethanol.,  during microwave heating has been studied. The percent of recovery of each plasticizer was determined using direct HPLC method. Stability was depended on heating (exposure) time, microwave power setting, and the nature of the food simulant. In general, studied plasticizers appeared to be more stable in 10%v/v ethanol, than in distilled water, The 3%w/v acetic acid showed good stability with the lower molecular weight compounds even at full power, while the higher molecular weight compounds decomposed rapidly.

Keywords: plasticizers, microwave, stability, migration, food simulants, HPLC.
