Alkyl phenol polyoxyethylene ether sulphonates were synthesized with AEO/APEO through halogenation and sulphonation reaction.It is believed that the sulphonation proceeds through S_N 2 substitution.The influences of the reaction conditions on the sulphonation were investigated by the experiment of L_(27)(3~(13)).At 70℃ and normal pressure,the yield of the product was 89.76% with sodium sulphite as the sulfonating agent.The results of the interracial tension test showed that the flooding system comprising 0.2% content of the surfactant has super low interfacial tension up to the level of 10~(-3) mN/m at 70℃,total salinity 80 g/L and the total content of Ca~(2+)/Mg~(2+) 0.4-1.1 g/L without alkali in the system.
