STUDY ON COMPONENTS OF FURFURAL RESIDUE FROM CORNCOB

In this paper,the components of furfural residue are analyzed.Total sugar contentoccupies47.36％ of absolute drying residue,and glucose occupies 83.23％ of total sugar content.Bycombining the phenyl nucleus exchange reaction with nitrobenzene oxidation,the quantity of struc-tural units of phenyl nuclei was determined,products from syringyl units occupy 50％ of klasonlignin Especially,diphenyl methane type syringyl units occupy 38.80％,and guaiacyl units 25％,other condensed guaiacyl units about 20％.The furfural residue is not a good material for the manu-facture of adhesives,but for active carbon.The yield of furfural residue may achieve about 350thousand tons per year,but it has not been used in industry in China.

Study on components of furfural residue from corncob

In this paper, the components of furfural residue are analyzed. Total sugar content occupies 47.36% of absolute drying residue, and glucose occupies 83.23% of total sugar content. By combining the phcnyl nucleus exchange reaction with nitrobenzene oxidation, the quantity of structural units of phcnyl nuclei was determined, products from syringyl units occupy 50% of klason lignin. Especially, diphcnyl methane type syringyl units occupy 38.80%, and guaiacyl units 25%, other condensed guaiacyl units about 20%. The furfural residue is not a good material for the manufacture of adhcsivcs, but for active carbon. The yield of furfural residue may achieve about 350 thousand tons per year, but it has not been used in industry in China.
