Abstract People pay more and more attention to quaternary ammonium salt for its good performance. Quaternary ammonium salt has been widely applied in oil field, food and daily chemical field. Capability of static adsorption of TPAC on the surface of Daqing oil sand under formation temperature (45℃) was studied, and the influence of liquidsolid ratio, adsorption time and concentration were discussed. The results show that when the adsorption of TPAC is saturated on the surface of Daqing oil sand: ratio of liquid to solid is 20∶1, concentration is 1.84 mmol/L, adsorption time is 6 h. The absorption isotherms is Sshaped curve. When the concentration becomes 1.10 mmol/L, it can form saturated monolayer adsorption membrane; and when the concentration becomes 1.84 mmol/L, it can form saturated bilayer adsorption membrane with a saturated adsorption quantity of 13.21×10-6 mol/g. The study of the adsorption capacity of quaternary ammonium salt will have a good base for its application in oil field.
