摘要：

New non-ionic surfactants based on alkylamine and poly(ethylene glycol) dimethacrylate were synthesized by one-step Aza-Michael addition reaction. The surfactants' chemical compositions, surface and interfacial activities, micellization, and zeta potential were characterized. Their surface and interfacial activities recommended the application as demulsifiers for water in Arabian heavy oil emulsions (w/o). The demulsification of this type of emulsion has attracted researchers' attention because of its high stability with water droplets in the microscale. The outcome of using the prepared surfactants showed high performance as emulsion breakers, as the demulsification efficiency reached 100% for w/o emulsions with different water to oil ratios (50:50, 30:70, and 10:90).
