Synthesis and properties of itaconic acid diester disulfonate Gemini surfactant
摘要
Abstract
A new type of Gemini surfactant (Gemini-12) was synthesized with cheap materials such as itaconic anhydride (IAn),lauryl alcohol,1,4-butanediol and sodium bisulfite by the monoesterification,sulfonation and diesterification reaction processes.The optimal reaction conditions of the diesterification obtained via orthogonal experiments were:ratio of sodium lauryl sulfoitaconic monoester to 1,4-butanediol=2.30 ∶ 1.00,and 1.0％p-methyl benzenesulfonic acid at 150℃C for 6.0h.The structures of intermediate products and Gemini-12 were confirmed by FTIR and 1H NMR.Finally,the primary physico-chemical properties of Gemini-12 were characterized.The critical micelle concentration (CMC) was 1.38 × 10-3mol/L,and the surface tension at CMC was 28.60mN/m;the efficient factor pC20 was 3.14;CMC/C20was 1.91;the saturation adsorptionΓcMc was 1.15mmol/m2;the area per molecule at interface was 1.44× 10-3nm2/mole;the standard free energy of micellization was-9.018kJ/mol and the standard free energy of adsorption was-31.22kJ/mol.The CMC of Gemini-12 decreased with the increase of the concentration of NaC1 solution.关键词
