TITLE: Infrared Spectra of Cellulose and of Its Dorivatives

ABSTRAOT: It is pointed out in the introduction tha 't cellmlooe as a
fiber could be investigated only inadequatelyp booauee light
dispersion presents a considerable obstacle in infrared
spectroscopic investigations. Attempts made to avoid this ob-
stacle by dissolving the fiberg or by emb,edding it in an im-
mornion medium, or oven by regenorating oellulooo to callo-
plutne gave entirely unsatisfactory results which did not show
the true cellulose spectrum. Thus, the autnore endeavored to
press cellulose fibers without any additionp and they invosti-
gated the spectrum of these pressed cellulose samples within
the range of from 2.5 to 15,*- In the spectra of native cel-
lulosee bande were found in the following ranges: 3330, 2940,
16,50, 1428, 1360, 1340, 1325, 1290, 1225, 1190, 1150L910 and
7015 om-1. The former is to be attributed to the OH-valence

band was found at 1740 am" (0-0). An inoireaeo of the degree of
oxidation attenuated the intensity of the bands 1430, 136o,
1340, and 1325 am and inoieased'the in-tensity of the band in
the range of .1280-1160 cm7l. Further details are,discussed in
this connection. A nitration reaulted in the ocourrence of the
bUndS 1290, 1390; and 1200 'am-1. The speot-rum of dialdehyde cel-
lulose was 'characterited by absorption i:ft the range of 900 am-1.
A cellulose with, many ca-rboxyl groups,- showed weak band at
955 am mercerized cellulose showed inareaspd absorption in the
range of-910 cm-1p eto,. In conclusions the great importance of
cellulose infrared spectroccopy'ia pointed out.'
