The Detection of Lignin acid. Color reactions have since found widespread use in the detection and identification of lignin and several have also been adapted for use in the quantitative determination of lignin. Recently, color reactions have been proposed for the detection of specific groups within the lignin molecule.作者: 才能 時間: 2025-3-22 03:20 作者: Palpate 時間: 2025-3-22 07:57 作者: 澄清 時間: 2025-3-22 08:47
Ultraviolet Microscopydifferentiating xylem. Both Lange (1954) and Wergin (1965) elucidated the unusual lignin distribution in compression wood by means of UV photomicrographs. Jayme and Torgersen (1967) reported on the topochemistry of delignification in sulfite and sulfate pulping of spruce wood using a Leitz UV microscope.作者: NORM 時間: 2025-3-22 14:48 作者: 繼承人 時間: 2025-3-22 20:22 作者: neutralize 時間: 2025-3-22 21:55 作者: Harness 時間: 2025-3-23 03:49
Isolation of Lignin from Pulpwood. The main difference between the two procedures is that chemical pulp, unlike wood, is digestible by cellulolytic enzymes without ball-milling. Consequently, this method provides an ideal method for the isolation of the residual lignin in chemical pulps without structural modification.作者: 音的強弱 時間: 2025-3-23 08:42

Initially, activity along these lines was fueled by a desire to interpret technical delignification (Le. , pulping) processes in terms of accompanying structural changes in the lignin.

Cross Polarization/Magic Angle Spinning Nuclear Magnetic Resonance (CP/MAS NMR) Spectroscopysolution improved sufficiently to reveal detailed structural information about solid lignin (Bartuska et al. 1980). The number of research groups using the technique then increased rapidly as commercial CP/MAS NMR equipment became available and wood scientists began to recognize the advantages of being able to characterize lignin in situ.作者: sphincter 時間: 2025-3-23 19:32

Fourier Transform Infrared SpectroscopySince the early 1950s, IR spectroscopy has been a routine analytical tool for lignin chemists. In the past, spectra were recorded using the so-called dispersive technique, i.e., with grating-type or prism instruments. In the last decade, Fourier transform infrared (FTIR) spectrometers have become increasingly available for routine laboratory work.作者: 記憶法 時間: 2025-3-24 02:42 作者: Frequency-Range 時間: 2025-3-24 09:18 作者: Glaci冰 時間: 2025-3-24 10:48 作者: Frequency-Range 時間: 2025-3-24 17:46
