  1. 1. Deepening the insights of lignin structure : Lignin-carbohydrate complex (LCC) fractionation and characterization and Kraft lignin amination

    Författare :Xueyu Du; Jiebing Li; Mikael Lindström; Jussi Sipilä; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Improvement of kraft pulping delignification efficiency and value-addition of industrial kraft lignin are two attractive topics. The proposal that delignification is deteriorated by the presence of lignin-carbohydrate complex (LCC) is still being debated. LÄS MER

  2. 2. Biochemical Control Aspects in Lignin Polymerization

    Författare :Anders Holmgren; Gunnar Henriksson; Liming Zhang; Jussi Sipilä; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Lignin polymerization; DHP; Ascorbic Acid; NADH; template polymerization; melanin; Chemistry; Kemi;

    Sammanfattning : Lignins are produced by all vascular plants and they represent one of the most abundant groups of biopolymers in nature. Lignin chemistry research, which has been of great importance for the progress of pulping technologies, has been plagued by the difficulties of its isolation and characterization. LÄS MER
