The abilities of sodium alkyl aryl sulfonate,which had high-purity and defined structure,to emulsify alkanes,were investigated by a water diversion method.Using liquid paraffin wax as the oil phase,the effects of the concentration of emulsion,length of alkyl chain,structures and locations of aryl groups in alkyl chain on emulsion stability were studied,and the best concentration of emulsion were determined.Meanwhile,the effects of different oil phases to emulsion stability were discussed.The experimental data showed that the best mass fraction of emulsion was 0.1%.With definite structures of aryl group,emulsion stability increased linearly with the increasing of the length of carbonic chain.When the length of alkyl chain on alkyl group was set,the emulsion stability was enhanced with the increasing of the length of alkyl chain on aryl group.With the aromatic ring shifts from the terminal to the center of the long alkyl chain,the emulsion stability increased.With the increase of molecular mass of oil phases,the molecular mass of emulsifier to achieve stable emulsifying liquid increased.
