                 Abstract: A sulfonate Gemini surfactant, N,N'-dipalmitoyl p-phenylenediamine diethyl sulfonate (DS16-P-
                 16) was synthesized by substitution and acylation reaction using p-phenylenediamine, palmitoyl chloride
                 and  sodium  2-chloroethyl  sulfonate  as  main  raw  materials.  The  intermediate  and  target  product  were
                                     1
                 identified by FTIR and  HNMR. The water solubility, surface/interfacial activity, foaming properties and
                 emulsifying  properties  of  DS16-P-16  were  investigated.  The  results  showed  that  the  critical  micelle
                                                        –4
                 concentration (CMC) of DS16-P-16 was 5.01×10  mol/L at 25 ℃, which was 6.26% of traditionalsurfactant
                 sodium dodecyl sulfate (SDS), pC 20 (the negative logarithm of the concentration of DS16-P-16 solution
                 required to reduce the surface tension of water by 20 mN/m) was 3.61, indicatedthat DS16-P-16 had a better
                 ability  to  reduce  water  surface  tension.  With  the  increase  of  experimental  temperature  and  solution
                 concentration, the interfacial tension between DS16-P-16 solution and crude oil in Jilin oilfield gradually
                                                –2
                 decreased,  both  were  lower  than  10 mN/m.  At  45 ℃,  0.5%  (mass  fraction)DS16-P-16  solution  could
                                                          –2
                 reduce the oil-water interfacial tension to 1.46×10  mN/m. The initial foaming height of 0.1% DS16-P-16
                 solution was 28 cm, the foam stabilization rate reached 93%, and the stable time of emulsion was 437 s.
                 Under the same conditions, the initial foaming height of 0.1% SDS solution was only 15 cm, the foam
                 stabilization rate was 60% and the emulsification time was 128 s.
