초록

대두유로부터 생산된 바이오디젤과 바이오디젤 혼합 연료유를 대상으로 산화 특성과 지방산메틸에스터 함량 등 화학적 분석을 수행하여 자동차용 연료로서의 품질특성을 파악하였다. 대두유로부터 생산된 바이오디젤은 불포화 지방산인 oleic acid, linoleic acid 및 linolenic acid가 85 wt% 이상 함유되어 있었다. 특히 활성 메틸렌기를 함유한 다불포화 지방산인 linoleic acid와 linolenic acid가 60 wt% 이상 함유되어 있어 상대적으로 자동산화가 쉽게 일어나는 것으로 판단된다. 산화반응시 주요 반응물질은 linoleic acid와 linolenic acid였으며, 이들의 라디칼 자동산화에 의해서 비점이 약 500 ℃ 전.후에 있는 탄소수 36 전.후의 고분자 물질이 형성되는 것을 확인하였다.

Biodiesel and its blend fuels from soybean oil were characterized for their oxidation to apply automobile fuel from the analysis of FAME (fatty acid methyl ester) and chemical properties. Biodiesel produced from soybean oil contained unsaturated fatty acids (> 85 wt%) such as oleic acid, linoleic acid, and linolenic acid. Especially, polyunsaturated fatty acids such as linoleic acid and linolenic acid containing active methyl radical were over 60 wt%. It is believed that linoleic acid and linolenic acid cause oxidation. Linoleic acid and linolenic acid during oxidation were major reactants, and compounds with the carbon number having around 36 (boiling point of about 500 ℃) were produced from those of radical autoxidation.

Keywords:FAME;bio-diesel oxidation;stability of oxidation;carbon number distribution
