Solubility and diffusivity of N,O and CO, In water were determined as a function of temperature from the results published In the open literature, and new data were measured In the present work. The solubllity of N,O in several aqueous aikanolamlne (DEA, DIPA, DMMEA, and DIPA) solutlons at varlous temperatures was measured and correlated over a wide range of conditions. For both the diffuslvity of N,O and the aikanolamlne In aqueous alkanolamlne solutions a modHled Stokes-Einstein relation was derived. With the ald also of the "N,O analogy" the diffusivity of CO, In these solutlons can be estlmated.
A study on the reaction between CO2 and alkanolamines in aqueous solutions Blauwhoff, P.M.M.; Versteeg, G.F.; Swaaij, W.P.M. van Abstract-Literature data on the rates of reaction between C0 2 and alkanolamines (MEA, DEA, DIPA, TEA and MDEA) in aqueous solution are discussed . These data induced us to carry out absorption experiments of C02 into aqueous DEA, DIPA, TEA and MDEA solutions from which the respective rate constants were derived . The experimental technique was similar to that used by Laddha and Danckwerts [30] .The results for DEA and DIPA were analysed by means of a zwitterion-mechanism which was derived from the mechanism originally proposed by Danckwerts[16], and were found to fit the model extremely well .The reaction rate of C02 with aqueous TEA and MDEA solutions shows a significant base catalysis effect which is also reported by Donaldson and Nguyen[17] and Barth et at. [ ]. The results for TEA correspond very well with those of Donaldson and Nguyen[171 and Barth et al. [ ] .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
