Abstract: The adsorption properties of eleven isomers of sodium alkyl m-xylene-aryl sulfonates with
odd-numbered alkyls (mcn-hes) on Daqing oil sands were measured, and the effects of initial mass
concentration, molecular structures, the length of carbonic chain of mcn-hs and accessory
chemicals on the adsorption capacity of mcn-hs in Daqing oil sands were discussed. The
experimental data showed that with the increase of mcn-hs initial mass concentration the adsorption.
amount first increased and slightly decreased after reaching its saturation value. With the aromatic
ring in mcn-hs molecule shifting from the terminal to the center of the long carbonic chain, the
adsorption capacity of micn-hs in Daqing oil sands decreased. With the increase of Nacl and NAOH
mass concentrations, the adsorption capacity of mchs in Daqing oil sands increased, while
decreased with the addition of isoamyl alcohol. Under the addion of accessory chemicals, the
adsorption capacity of mcn-hs in Daqing oil sands decreased with the increase of the carbonic chain
length in mcxn-hs molecule
