Performance of palmitoyl diglycol amide and its anionic and nonionic derivatives in reducing crude oil/water interfacial tension in absence of alkali

- Palmitoyl diglycol amide (PDGA) was synthesized and characterized.
- Anionic and nonionic derivatives of PDGA were synthesized and characterized.
- IFT behavior of these products for surfactant-polymer flooding was evaluated.
- Performance is found to correlate with their cross section area at interface.
- Those with small cross section area at interface give better performance.
