| Inhoud: |
High yields of D-glucose and D-xylese water soluble oligosaccharides were obtained by extraction of birch wood with anhydrous hydrogen fluoride at sub-ambient or ambient temperature. A small amount of carbohydrates remained in the resulting insoluble lignin. Investigation b) infrared spectroscopy as well as phenolic group analyses indicated a probable low level of aryl alkyl ether linkage cleavage, at least in the range of the reaction conditions studied. Alkaline nitrobenzene oxidation of lignin showed that, condensation occurred, as measured by the decrease in yield of total p-hydro-xybenzaldehydes, during the hydrogen fluoride treatment. |
