Cleavage of the natural lignin of cotton-plant stems with thioacetic acid in the presence of anthraquinone

  • Published:
Chemistry of Natural Compounds Aims and scope

Abstract

The influence of additions of catalytic amounts of anthraquinone on the stages of hydrolysis in the cleavage of natural lignin by thioacetic acid has been investigated. The degree of delignification does not change under these conditions, but the yield of low-molecular-weight cleavage products increases, which indicates a profound degradation of the lignin macromolecule. The qualitative and quantitative compositions of the monomeric fractions of cleavage products do not undergo appreciable changes in the presence of anthraquinone.
