Study on Influence Factors of the Stability of Inverse Microemulsion of ACRYLAMIDE

WANG Jian-ming;CHEN Wen-mi;School of Metallurgy and Environment,Central South University;  
Water-in-oil(W/O) microemulsion was prepared by using the composite emulsifier and taking liquid alkanes as the continuous phase, acrylamide aqueous solution as the disperse phase. Then, for the purpose of obtaining the maximum solved water phase, the influences of such factors as type of continuous phase, emulsifier composition, concentration of acrylamide monomer and salinity on the microemulsion stability were investigated by means of visual inspection and conductivity measurement. The optimum conditions for preparing the microemulsion were finally obtained. Experimental results show that, when the Isopar M is used as continuous phase,Span80/OP-10 is used as composite emulsifier and moreover the mass fraction of Span80 in the composite emulsifier is 80%, the system can obtain the maximum solved water phase. And that,with the increasing of the concentration of acrylamide and adding proper amount of electrolytes Na Ac, the stability of the microemulsion can be improved. In addition,the optimum HLB value of emulsifier is also improved by the addition of electrolytes.
