本文通过对醇和胺的界面张力的测定,获得了醇和胺的饱和吸附量和分子面积;指出了叔胺法制碱中的醇和胺都是表面活性物质;建立了界面相模型,认为在实验浓度范围内表面活性物质的界面浓度是主体相浓度乘上一个常数。由此导出了碳化反应模型,并且进一步得到了实验验证,说明了碳化机理的可靠性。 In this paper, the saturated adsorption amount and molecular area of ​​alcohols and amines were obtained through the determination of the interfacial tension of alcohols and amines. It was pointed out that the alcohols and amines in the base of tertiary amines were all surface-active substances. The interfacial phase model was established, The concentration of the interfacial surface active material is the concentration of the main phase multiplied by a constant. From this, the carbonation reaction model was derived and further verified by experiments, indicating the reliability of the carbonization mechanism.
