Abstract
AbstractThe reaction mechanism of carbon dioxide with diethanolamine (DEA) is investigated using the stopped‐flow method with optical detection in the ranges of concentration [DEA] = 0.111–8.4 × 10−2Mand [CO2] = 2.94–5.6 × 10−3M. The comparison of the fast time‐dependent light transmission change of a pH indicator with theoretical simulations of integrated rate equations requires a kinetic model in which a simple carbamate formation takes place simultaneously with hydration reactions, whose contributions are far from being negligible. A first‐order reaction relative to DEA is thus found with a rate constant for carbamate formation smaller than usually predicted (110 ± 15M−1s−1at 25°C). The equilibrium constant for the same reaction is also determined giving pKR= 5.3 at 25°C, in satisfactory agreement with values assumed so far.
