The Liquefaction Mechanism Research of Straw Fiber in Polyhydric Alcohol

Article Preview

Abstract:

Two key products were isolated and purified from liquid mixture composition of wheat straw, by means of a combination of organic solvent extraction and column chromatography. Their structures were identified on basis of nuclear magnetic resonance (1H-NMR, 13C-NMR, DEPT), mass spectrometry (MS), and infrared (IR). The mechanism of liquefaction of straw was inferred from the structures of products and changes of hydroxyl value and liquefaction residue, which make up the lack of mechanistic studies of overall utilization of plant fibers.
