摘要： 测定了丙酮-正己烷、甲苯-正己烷、苯-正己烷、正戊烷-正己烷4个二组分气体在硅烷化硅胶上的吸附等温线,并测定了单组分气体吸附等温线。实验结果表明:二组分气体在硅烷化硅胶上的竞争吸附的强弱可以通过其单组分气体在硅烷化硅胶上第一层吸附热Q_1数值的大小预测。

Abstract: In this paper,the binary adsorption isotherms of acetone-n-hexane,toluene-n-hexane,benzene-n-hexane and n-pentane-n-hexane on silylanization silica gel are presented.The adsorption isotherms for pure gas are also obtained.It will be seen from the experimental results that the adsorption behavior of the vapor mixtures can be predicted from the isotherms of pure components.The extent of predominant adsorption can be predicted by the first layer adsorption heat of the individual pure components.

Key words: Binary gas adsorption, Acetone-n-hexane, Toluene-n-hexane, Benzene-n-hex-ane, n-Pentane-n-hexane, Silylanization silica gel
