摘要：
Acetonlignin isolated from aspen wood was characterized by elemental analysis and FTIR spectroscopy. The composition of liquid products of acetonlignin conversion over NiCu/SiO2 catalysts in supercritical butanol at 300 degrees C and pressure 2.4-5.0 MPa was studied by CMS method. It was found that the catalysts intensify the reactions of butanol conversion and increase by 1.8 times the yield of hexane-soluble products. Liquid products of catalytic conversion of acetonlignin are characterized by high content of esters and the reduced concentration of methoxyphenols as compared to liquid products obtained in the absence of catalyst.
