PEROXIDE PULPING PROPERTIES OF ANNUAL PLANTS. 2. THE DYNAMICS OF TRANSFORMATION OF POLYSACCHARIDES IN THE DELIGNIFICATION OF WHEAT STRAW
Abstract
The dynamics dissolution of wheat straw polysaccharides during the oxygen delignification process was investigated with reaction mixture «H2O2 – H2O– АсОН – АсООН-catalyst». In the first period of peroxide pulping (until the release of solid residue 80–82%) mostly dissolve lignin and arabinoksilan. Further decline in output if you continue cooking comes at the expense of the dissolution products of oxidative and hydrolytic degradation of polysaccharides of solid residue.Downloads
