由石油烃制得的高级脂肪醇含有许多杂质。其中烃的含量是评价脂肪醇质量的一项重要指标,通常用低压液相柱色谱法或反应色谱法进行测定。但是低压液相柱色谱法操作较繁,准确度不高,而反应色谱法在缺乏有效和热稳定的消除试剂时,其应用也受到限制。高压液相色谱法是测定醇中烃的较好方法。这种方法成功地用于测定醇中的二
Higher fatty alcohols made from petroleum hydrocarbons contain many impurities. Among them, the content of hydrocarbons is an important index to evaluate the quality of fatty alcohol, which is usually determined by low pressure liquid column chromatography or reaction chromatography. However, the low pressure liquid column chromatography is complicated and the accuracy is not high. However, the application of reactive chromatography in the absence of effective and thermostable elimination reagent is also limited. High pressure liquid chromatography is a good method for the determination of hydrocarbons in alcohols. This method has been successfully used to determine two in alcohol
