Efficient non-aqueous solvent formed by 2-piperidineethanol and ethylene glycol for CO2 absorption?
Chemical Communications Pub Date: 2019-09-23 DOI: 10.1039/C9CC06320J
Abstract
The non-aqueous solvent formed by 2-piperidineethanol (2-PE) and ethylene glycol (EG) exhibited a high CO2 capacity of up to 0.97 mol CO2 per mol amine at 25 °C and 1.0 atm and a low regeneration temperature of 50 °C, indicating the low energy consumption in the regeneration process. Surprisingly, CO2 directly reacted with EG by forming a carbonate species, proved by FTIR and NMR results.
