Chemical reaction kinetics of carbon dioxide with aqueous solutions of D (+) glucosamine hydrochloride (2‐amino‐2‐deoxy‐ D ‐glucose hydrochloride) has been studied using a stirred tank reactor with a planar interfacial area. The operational variables considered in this work have been the glucosamine concentration and the reaction temperature. Specific absorption rates have been obtained and different correlations have been employed to estimate physicochemical properties of carbon dioxide in glucosamine aqueous solutions. Results indicate that the absorption process occurs in a moderately fast reaction regime with a first‐order kinetic for amine and carbon dioxide. The reaction rate constant was calculated and correlated as a function of temperature. © 2007 American Institute of Chemical Engineers AIChE J, 2008
