摘　　要：运用硅胶三氧化二铝柱+硅酸柱分离原油中的烷基酚类化合物,用BSTFA试剂硅烷化,然后进行色质分析。比较了3种分离方法的优劣,进行了硅烷化等实验条件的试验。研究表明,用硅胶三氧化二铝柱可以对原油中的烷基酚进行富集,由于硅酸的极性较强,因而减少了苯酚和甲酚的损失,同时也降低了非烃中其它极性组分对分析的干扰,延长色谱柱的寿命。烷基酚的含量与水洗和氧化作用有关,水洗和氧化作用越大,烷基酚的含量损失越大。本方法的最大相对偏差小于15%,标样回收率达到89.60%。The alkyphenol compound in crude oil was separated by the silica get alumina and silicic column and silanized with BSTFA, and then was analyzed with GC--MS. Three ways of separation were compared in this study, and the conditions of silanization were tested. It was concluded that alkylphenol compound could be enriched with silica gel alumina column, and the loss of phenol and cresol could be reduced because of the polarity of silicic acid, so that the influence of other polar component in nonhydrocarbon would be reduced. The content of alkylphenol had something to do with the water washing and oxidation action, the more water washing and oxidation action, the more loss of the content of alkyl phenol. The max relative deviation in this method was less than 15%, and the recovery rate of the standard sample reached 89.60%.
