메탄올 용액에서 산소 첨가된 Co(III) 착물을 촉매로 사용하여 흡광광도법에의한 2,6-di-tert-butylphenol(DTBP)의 산화반응에 대하여 알아보았다. 산화반응의 결과로서 주 생성물은 2,6-di-tert-butylbenzoqu-inone(BQ)였고 산소 첨가된 착물의 촉매 활성은 [Co(III)2(SMPD)2(Py)2]2O2가 [Co(III)2(SPPD)2(Py)2]2O2보다 더 컸으며 속도상수(K)는 4.55∼2.12${\times}$10-3/s의 값으로 주어졌다. 또한 산화반응은 촉매, 산소분자 및 기질의 노도에 1차 반응임을 확인하였으며 활성화 에너지(Ea)가 10.38kJ/mol로 주어져 Arrhenius의 특성에서 벗어는 결과를 보였다.

Accurate analysis of petroleum hydrocarbons in soil is an important prerequisite for proper source tracking of contamination. Identification of petroleum compounds is commonly carried out by peak pattern matching in gas chromatography. However, this method has several technical limitations, especially when the soils underwent biological, physical and chemical transformation. For instance, it is very difficult to distinguish jet fuel (JP-8) from kerosene because JP-8 is derivatized from secondary reaction between chemical agents (e.g. anti-oxidants, antifreezer and so on) and kerosene. In this study, an alternative method to separately analyze JP-8 and kerosene in the petroleum hydrocarbon contaminated soil was proposed. Qualitative analyses were performed for representative phenolic antioxidants [2,6-di-tert-butyl phenol (2,6-DTBP), 2,4-di-tert- butylphenol(2,4-DTBP), 2,6-di-tert-butyl-4-methyl phenol (2,6-DTBMP)] using a two dimensional gas chromatograph mass spectrometer (2D GC×GC-TOF-MS). This qualitative analysis of antioxidants in soil would be a useful complementary tool for the peak pattern matching method to identify JP-8 contamination in soil.
