长链烷基酚是生产表面活性剂和润滑油添加剂的主要原料。是由烯烃和苯酚进行烷基化反应得到的产品。用不同的烯烃原料和用不同的催化剂进行反应时,得到的烷基酚的组成是不相同的。测定长链烷基酚的组成,曾采用过各种方法,尤其是液体色谱法。然而,由于液体色谱的分离效率低,不能将烷基酚中各组分按结构组成进行完全地分离。微型液体吸附色谱用硅胶柱很好地分离了2,6-二烷基酚和4-烷基酚,但2,4-二烷基酚和2-烷基酚却从柱中一同洗脱
Long-chain alkylphenols are the main raw materials for the production of surfactants and lubricant additives. Is the product of alkylation of olefins and phenol. With different olefin feedstocks and with different catalysts, the composition of the alkylphenol obtained is different. Determination of long-chain alkylphenol composition, have used a variety of methods, especially liquid chromatography. However, due to the low efficiency of liquid chromatographic separation, the individual components of the alkylphenol can not be completely separated by the structural composition. The 2,6-dialkylphenol and 4-alkylphenol were well separated on a silica gel column using a miniature liquid adsorption chromatography, but the 2,4-dialkylphenol and 2-alkylphenol eluted from the column together
