Dissociation constants and thermodynamic properties of alkanolamines

The dissociation constants of protonated 2-amino-2-ethyl-1,3-propanediol (AEPD), 2-amino-2-methyl-1-propanol (AMP), diethylmonoethanolamine (DEMEA), diisopropanolamine (DIPA), dimethylmonoethanolamine (DMMEA), monoethanolamine (MEA), 1-amino-2-propanol (MIPA), and methylmonoethanolamine (MMEA) have been determined by electromotive force measurements from (293 to 353) K. The experimental results and derived values of the standard state thermodynamic properties are reported. © 2009 Elsevier Ltd. All rights reserved
