Analysis of 3 - tert . - Butyl - 6 - methyluracil by Gas Chromatography

3-特 丁基-6-甲基脲嘧啶的气相色谱分析研究

Studies showed that α naphthol and non alkyl substituted phenol in ortho position of hydroxyl can promote sediment formation and β naphthol 2 di methyl cresol and 2 di tert butyl para cresol can restrain sediment formation .

结果表明，α-萘酚和羟基 邻位有未被烷基取代的酚类能促使柴油氧化沉渣的形成，而β - 萘酚和受阻型酚类可抑制氧化沉渣的产生 。
