The mechanism of the absorption of carbon dioxide by an aqueous solution of monethanol‐amine has been studied. Experimental results for the absorption of carbon dioxide into a laminar jet of amine solution have been used to examine the transfer process. Previously this process has been considered as pseudo unimolecular, but this has been disproved. When considered as a second‐order, fast, irreversible reaction by the film, penetration, and corrected penetration theories, the results are most satisfactory. It is possible by the corrected penetration theory to correlate the results such as to predict k L / k Lo to within 3% of the experimentally determined value.
