LABORATORY SCALE PRODUCTION OF HYDROXYPROPYLMETHYLCELLULOSE (HPMC) IN A GAS-TIGHT REACTOR UNDER PRESSURE AND ITS APPLICATION IN CEMENT PASTE

Mustafa DOLAZ

Unfortunately, cellulose, which is the most abundant of natural polysaccharides in the world, and is found in high amounts in cotton and the waste/by-products of textile factories, cannot be recycled sufficiently. As an attempt to find a solution to this problem, in this study, a by-product of the towel production process, called towel clippings (TC), was used as a source of cellulose for obtaining HPMC. HPMC was synthesized for the first time from the reaction of cellulose, propylene oxide (PO) and chloromethane (CM) under pressure in a gas-tight laboratory scale reactor and then evaluated as ...Daha fazlası
