Evaluation of acidic paper deterioration in library materials by pyrolysis-gas chromatography

Effect of cellulose, hemicellulose and lignin contents on pyrolysis and combustion of natural fibers

“…The presence of a low amount of lignin seems to change the cellulose degradation pathway, promoting dehydration and further char formation at the expense of depolymerization. It has been shown in the literature that acidic catalysts are likely to enhance dehydration reaction and charring [33,34]. For example, Dobele et al [33] have shown that cellulose impregnated with phosphoric acid gives dehydrated cyclic structures in the solid phase during pyrolysis.…”

Effect of slight chemical modification on the pyrolysis behavior of cellulose fibers

“…Dobele et al [20][21][22] studied the dehydration reactions of cellulose in the presence of phosphoric acid and high levoglucosenone yield was achieved, while levoglucosan formation was hindered. Increased pyrolytic yield of levoglucosenone was also observed from paper deteriorated in acidic environment [37]. Fabbri et al [38][39][40] studied the preparation of various anhydroglucoses from cellulose with the application of catalysts.…”

Characterization of Korean handmade papers collected in a Hanji reference book

“…Investigation on traditional East Asian handmade papers employed a variety of material characterisation methods such as physical property measurements [22,23,30], microscopy observation [31][32][33] and chemical composition analysis [34][35][36]. On-line pyrolysis hyphenated with gas chromatography/mass spectrometry (Py-GC/MS) is among the most frequently used techniques for cellulosic material studies due to simple preparation with minimum quantity required [37][38][39]. Its practical application on Japanese and Chinese handmade papers was previously explored as a new approach for East Asian handmade paper characterization [3,40,41].…”
