Description

Application

• CO₂ Capture: 1-Methyl-2-pyrrolidinone is used in bench-scale CO₂ capture processes due to its excellent solvent properties. Recent research has demonstrated the effectiveness of NMP in combination with 2-(ethylamino) ethanol and water in capturing CO₂ efficiently. This application is crucial for developing sustainable methods to reduce carbon emissions from industrial sources (Qi et al., Fuel, 2023).
