Beschreibung

Allgemeine Beschreibung

Cellulose, a homopolymer consisting of glucose units joined by beta-1,4 bonds. These are strongly attached through inter and intramolecular hydrogen bonds and van der Waals forces resulting in microfibrils which together form fibers. They are arranged in parallel reducing ends of adjacent glucan chains.[1] Cellulose is widely used as sorbent in TLC.[2]

Anwendung

Hochreines Cellulose-Pulver für die Verteilungschromatographie

Cellulose was used to measure the cyrstallinity index using X-ray diffraction (XRD) patterns and solid-state 13C nuclear magnetic resonance spectra.[3]
