The Solubility of Deep Eutectic Solvents Derived from Allytriphenylphosphonium Bromide in Supercritical Carbon Dioxide in the Presence of Ethanol as a Cosolvent
Two distinct deep eutectic solvents (DESs) were prepared by combining allyltriphenylphosphonium bromide (ATPPB) as a hydrogen bond acceptor (HBA) and ethylene glycol as a hydrogen bond donor (HBD) at molar rat...
