Effects of Additives and Structure on Adsorption of Pentadecylaryl Sulfonates on Oil Sands
Abstract:
The isotherms and the amount of adsorption of pentadecyl aryl sulfonates with high purity synthesized in our laboratory on oil sands were determined at 45℃.The effects of the concentrations of surfactants,NaCl,NaOH,NaHCO3,n-butyl alcohol and molecular structures of surfactants on pentadecyl aryl sulfonate adsorption were investigated.The experimental results show that with increasing the concentrations of the sulfonates,the absorption capacity was firstly increased,and then decreased.The absorption capacity increased with the addition of NaCl and NaOH while decreased with the addition of n-butyl alcohol and NaHCO3. Moving the aryl from the terminal to the center of the long alkyl chain,the absorption capacity decreased,and the impact of accessory was reduced.
