Infrared Spectrophotometric Procedure for Analysis of Cellulose and Modified Cellulose

Studies and Experimental Investigations in Connection With Chemical Bonding in Resin-Treated Cellulose

“…However, in the present work a sharp spectrum for cotton cellulose comparable to that shown by O'Connor et al [14), was obtained even though a high-speed vibrator-type ball mill was used in sample preparation. The untreated cellulose I spectrum (sample A) shows all characteristic bands previously reported (14,17]. The main bands observed and their assignments, based on literature data, are given in Table IV. -10- [19), were as follows.…”

“…It has been indicated that the infrared spectra (IR) of cotton cellulose and cellulose derivatives can provide information as to the nature and position of i1odifying substituents and, in many cases, the extent of chemical modification may be quantitatively estimated (14). Therefore the infrared spectra of the resintreated cotton samples have been investigated using a Perkin-Elmer…”

“…O'Connor et al [14], and -leverly and Herrmann (161 observed that the ball milling of cellulose in the preparation of KBr pellets or Nujol mulls caused changes in the IR spectrum involving loss of definition and certain bands due to changes in crystallinity.…”

Chemistry of Hyphal Walls of Phytophthora

“…Infrared spectra of Phytophthora walls showed a much greater similarity to the spectra of amorphous cellulose (cf. O'Connor, DuPre & McCall, 1957) than to that of cellulose I.…”

Dynamic rheology behavior of electron beam-irradiated cellulose pulp/NMMO solution

“…The crystalline structure of irradiated cellulose pulp was studied by FTIR with KBr grinding (O'Connor et al, 1957). IRspectra were recorded using a Nicolet Avatar 370 FT-IR spectrometer with a DTGS detector at 4 cm À1 resolution in the 375-4000 cm À1 region scanned 10 times.…”
