Abstract

Abstract: Acrylamide inverse-phase emulsion was prepared with kerosene as organic medium,sorbitan monooleate (Span 80) and alkylphenol polyoxyethylene ether (OP-10) as blended emulsifier,as well as impinging stream-rotating packed bed reactor as emulsification equipment.Effect of super gravity factor,impinging speed,volume ratio of oil to water,mass fraction of emulsifier,HLB value of the blended emulsifier and mass fraction of acrylamide monomer content on stability of the emulsion was studied.Comparison was made with that obtained with stirring emulsification device.Results showed that at the conditions of 65.32 super gravity factor;12.58 m/s impinging speed;1∶1 volume ratio of oil to water;5% mass fraction of emulsifier in total emulsion;6.0 HLB value of the blended emulsifier and mass fraction 15% of acrylamide monomer in water solution,the average emulsion particle size of the emulsion achieves 664 nm,and stability coefficient can achieve 0.973.Comparison study showed that stability,particle size and dispersion of emulsion prepared with impinging stream-rotating packed bed reactor is better,emulsification time is shorter,and the preparation process of the emulsion is continuous.

Key words: acrylamide inverse-phase emulsion, impinging stream-rotating packed bed, stability
