摘要
本文是在研究以多醣类物质作吸附剂制取无水乙醇的新工艺基础上,采用迎头色谱法测定了吸咐等温线,突验数据通过回归分析,获得符合Freundlich型的吸咐等温方程,计算值与实验结果吻合较好。实验还证明了多醣类物质在实验的温度范围内,选择性地吸附水蒸汽,而不吸附乙醇蒸汽。
The line of isothermal adsorption with polysacharidcs adsorbent at 70℃ , 80℃ and 90℃ respectively is determined by the method of frontal chromatography in this paper. Experimental results can be fitted satisfactorily with the equation of isothermal adsorption for Freundlich. It is found that the aqueous vapor can be adsorbed selectively on the polysacharidc adsorbent bat the vapor cthanol can't.
