crystalline cellulose

Microcrystalline Cellulose is an isolated, colloidal crystalline portion of cellulose fibers. The relative amounts of celluloses I and I vary with the source of the cellulose, with the I form being dominant in higher plants. In the case of Microcrystalline cellulose, cellulose is treated with mineral acids, followed by purification and spray-drying, and optionally, milling. crystallinity, due to the large number of intermolecular hydrogen bonds between adjacent hydroxyl groups, is mainly responsible for the insolubility in water. The Microcrystalline Cellulose monograph will be incorporated into and become official with the Second Supplement to the USP 42-NF 37. One-chain models of glucose hexamer, in which the interchain hydrogen bonds of real cellulose crystals are absent, do not exhibit the correct reaction behavior of levoglucosan formation; for.
