Carbon Dioxide Solubilities in Decanoic Acid-Based Hydrophobicdeep Eutectic Solvents

To alleviate drawbacks like high toxicity, high cost, non biodegradability etc, deep eutectic solvents (DES's) were found and are the modern solvents that have the caliber to ameliorate these fallibilities and we use these solvents to examine the potential of CO2 as a capturing agent. The preparation of DES takes mixing of decanoic acid and quaternary ammonium salt with variegated halide anions and alkyl chains.Varying temperature from 298 to 323 K and at a maximum pressure of 2MPa, six unique hydrophobic DES's were put in to be discerned and outcomes have been innumerated after solubility data with existent hydrophilic DES's, contemporary physical solvents and fluorinated ionic liquids have been tallied. All this has been done with a motivation to wander into a new arena of measuring CO2's solubility in DES's and such experiments prove the potency of CO2 as a capturing agent. The measured CO2 solubilities have nuance differences with those of fluorinated ILs but CO2 absorption lies in the bracket of those of nonpolar solvents.
