Optimisation of hybrid surfactant chemical structure for water-in-C02 microemulsions stabilisation (IR)

This research aimed to investigate the optimisation of hybrid CO2-philic surfactant chemical structure in stabilising water-in-Oo- (w/c) microemulsions. The optimisation was carried out by synthesise anionic surfactants analogue of AerosolOT(sodium bis (2-ethylhexyl) sulfosuccinate) template with th...
