| Abstract: | The reaction of ozone with lignin in aqueous acidic solutions is investigated. The Danckwerst model is used to describe the
kinetics of gas/liquid processes occurring in a bubble reactor. The efficient ozonation rate of a soluble lignin analog, sodium
lignosulfate, is determined. The main lines of the reaction between ozone and lignin are revealed on the basis of kinetic
analysis results and IR and UV spectroscopy data. |
