摘　　要：酚类化合物是重油催化裂化柴油中主要的酸性物质组分 ,在重油催化裂化柴油中共鉴定出 7类 40 0余种酚类化合物。实验表明 ,碱萃取是分离催化裂化柴油中酚类化合物的有效方法 ,碱浓度对酚的抽出率及酚类化合物的相对组成有很大影响。对国内几家炼厂生产的催化裂化柴油的比较发现 ,重油催化裂化柴油酚类化合物含量普遍偏高 ,相对含量也存在较大差异。对不同氧化程度的柴油进行分析发现 ,在柴油变质过程中 。Approximate 400 kinds of phenolic compounds divided into seven classes are identified in a caustic extract from the catalytic diesel oil. The alkaline extraction is the best method for separation and analysis of phenolic compounds. The concentration of alkali has a great effect on the yields and components of phenolic compounds. The catalytic diesel fuels produced from Dagang, Yanshan, Jinxi oils are studied respectively. The results show that the yields of phenolic compounds separated from different diesel fuels are differential. After ageing at ambient temperature, the distribution of phenolic compounds has changed. The content of phenolic compound in diesel fuel cracked with residual oils is high.
