DOCUMENT TYPE: Journal CA Section: 43 (Cellulose, Lignin, Paper, and Other Wood Products) Section cross-reference(s): 44 The levoglucosan (I) [498-07-7] content of the tars obtained upon pyrolysis of various cellulosic materials in vacuo was detd. by thin-layer chromtog., IR spectrophotmetry, and gas chromatog. The tar was then converted into glucose (II) [50-99-7] by hydrolysis with dil. H2SO4. The yields of I were ~2% from wood and ~22% for filter paper. The amt. of II was 1.6-2.6 times higher than that of I, indicating the presence of anhydro-sugars other than I in the tar.Except for chemicals metioned above, 50-99-7 and 498-07-7 are also used. .
