Switchable Chemicals for a Greener Oil Industry
Can CO2-triggered switchable surfactants be used to solve problems in the oil industry? Can such surfactants be designed to have low environmental impact? CO2-triggered surfactants are compounds that exist in two forms, of which only one is an effective surfactant; switching between the two forms is achieved by the introduction of CO2 (for one direction) and removal of the CO2 (for the other direction). Design parameters and applications will be described. Mention will also be made of switchable hydrophilicity solvents and their application to greening the oil industry.
