Study on Thickening Properties of Dodium α-alkenyl Sulfonate in Acid System
The thickening properties of sodium α-alkenyl sulfonate in hydrochloric acid,sulfuric acid,phosphoric acid,sulfamic acid,oxalic acid,citric acid and glycolic acid solutions were studied.The effects of sodium chloride and sodium sulfate at different concentrations on the viscosity of the system were investigated.The results showed that sodiumα-alkenyl sulfonate had self-thickening property in hydrochloric acid and sulfuric acid solutions,and sodium chloride or sodium sulfate was needed to thicken the system in other acidic solutions.
