催化柴油中的酚类化合物及其对柴油安定性的影响

催化裂化柴油用１０％的碱－醇（５：１体积）萃取，得到了０．５～０．８Ｗ％（相对柴油）的酚的混合物。通过色质分析，鉴定出了６９种酚，其结构比文献报道的从催化柴油中分离的酚的结构要复杂得多。这些酚的混合物对柴油的颜色和沉渣有明显的影响。元素分析表明其中还含有硫氮化合物。

IDENTIFICATION OF PHENOLIC COMPOUNDS IN LCOs AND THEIR EFFECTS ON STABILITY OF DIESELS

Phenolic mixtures were obtained from LCOs by caustic extraction. More than 69 phenols were identified by GC/MS and the phenolic mixtures had dramatic effects on the stability of LCOs in formation of color and sediments. Phenols in LCOs were more complex in structures and amounts than the results obtained by other researchers. The percentages of phenolic mixtures were 0.5～0.8 w% (based on LCOs). There were also nitrogen- and sulfur-containing compounds in the phenolic mixtures beside phenols.
