Conversion of veratrol and sodium lignosulphonate (LS) is studied in sub- and supercritical water (SCW) in the temperature range 200÷430 °C at 220 atm and the residence times 2.5÷10 min. Soluble products of the LS depolymerization are analyzed using HPLC and GC-MS. Thermogravimetric, elemental, IR and NMR spectral analyses of insoluble products of LS conversion are carried out. It is shown that methoxyaril ether bonds and aromatic structures do not undergo any destruction in SCW. The formation of insoluble precipitate is related to decarboxylation and desulfonation of lignin polymeric fragments.
