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。
In this work, the surface chemical properties of n-butanol, t-butyl alcohol and sodium lauryl sulfate mixed system were investigated. The logarithm of the surface tension and logarithm of a series of mixed solutions was discussed. The effects of surface activity, surface adsorption and adsorption layer In the molecular interaction. The results showed that the addition of butanol increased the surface activity and increased the mixed adsorption. The two components had obvious interactions in the surface layer. The linearity of n-butanol over branched-chain tert-butyl alcohol was higher than that of sodium lauryl sulfate Improve a greater role.
