Abstract

In this report, a kind of fatty acid esters of isethionate was synthesized with myristic acid and sodium hydroxyethyl sulfonate as raw materials and methane sulfonic acid as catalyst. Then, the effects of molar ratio of reactants, reaction temperature, catalyst dosage and reaction time on the product yield were discussed. The optimal reaction conditions are determined as follows: the molar ratio of myristic acid to sodium hydroxyethyl sulfonate was 1.2, the reaction temperature was 160 oC, the weight ratio of methane sulfonic acid to myristic acid was 2.5 , the reaction time was 4 hours, the obtained product yield was 68.7%. Finally, the surface activity of as-obtained product was evaluated by the surface tension (28.4 mN/m) and the critical micelle concentration (1.21×10-3 mol/L), indicating that the product is a fine Surfactant.
