摘要
本工作研究了正丁醇和叔丁醇与月桂基硫酸钠混合体系的表面化学性质,自一系列混合溶液的表面张力一浓度对数关系分析、讨论了体系的表面活性、溶液表面吸附和吸附层中的分子相互作用。结果表明,加入丁醇使表面活性提高,混合吸附增大;两组分在表面层中有明显的相互作用;直链的正丁醇比支链的叔丁醇对月桂基硫酸钠的表面活性提高有更大的作用。
The surface-chemical properties of the n-butyl alcohol-,t-butyl alcohol-sodium laurylsulfate systems had been investigated. The surface activities, sur face adsorptions and molecular interactions in the adsorption layer had been studied and discussed by analyzing the surface tension-concentration relationships of the mixed systems. The results showed that(1) the surface activities and the surfactant adsorptions of the mixed system enhanced by addition of butyl alcohol, and there wes an abvious molecular interaction between the two surfactant components in the surface layer; (2) the butyl alcohol with a straight chain (n-C4H9OH) had a greater surface activity enhancing effect on sodium laurylsulfate than that of branching chain(t-C4H9OH),
