本文测定了硅胶自四氯化碳中对直链脂肪醇的单元、二元和三元混合物的吸附.实验结果表明Langmuir型的混合吸附公式对这类体系基本可以应用.以相应吸附量作图皆得斜率为负的直线,且直线的负斜率不因被顶物和顶替物分子的链长改变而不同.上述结果可以用单分子吸附层和醇分子在硅胶-四氯化碳界面上是垂直取向的模型而得到合理的解释.

The adsorption of single and mixed normal aliphatic alcohols from dilute carbon tetrachloride solutions by silica gel has been determined.The experimental results of single alcohols(C2,C6,C8) may be expressed by Langmuir equation.Careful study of the adsorption from the following binary and ternary mixed aloohols:C4 C8,C5 C8,C4-C5 C8,indicates that the adsorption of any one alcohol is less than that of the alcohol from a solution of the alcohol alone.
