Synthesis and application of amphiphilic ionic liquid based on acrylate copolymers as demulsifier and oil spill dispersant

摘要

New poly(ionic liquid)s, PILs, based on quaternized ethoxylate octadecylamine acrylamido-2-methylpropane sulfonate-co-acrylic acid (AMPS/AA) copolymers were synthesized using radical polymerization. New hypothesis for demulsification of petroleum crude oil:water emulsions was elucidated from zeta potential measurements of water crude oil emulsions in the presence and absence of the prepared PILs. The prepared PILs based on AMPS/AA copolymer showed greater demulsification and dispersion efficiencies for petroleum emulsion and oil spill, respectively. The data were confirmed by optical microscope and average particle size distribution for crude oil emulsions. (C) 2016 Elsevier B.V. All rights reserved.
