the posidonia oceanica and its waste products and materials: cellulose direct chemical modification

摘要

the debris of posidonia oceanica accumulate every year on the beaches of tunisia. the cleaning of the beach, at the beginning of each season requires great efforts and expenditure. the recovery of the debris can be an economically very interesting. the rate of posidonia oceanica contains a large enough cellulosic materials.the different paths of recovery that we present in this patent are the use of the cellulose after extraction or directly using the raw materials. the compounds based on cellulose or its derivatives are used in the production of a very wide range of commercial products.these products can be used in various industries ranging from paper and packaging industry, textile and food processing. the currently used in the manufacture of cellulose and a variety of industrial products mainly comes from trees, other plants such as alfa were also harvested.this cellulose was extracted by different methods, and then purifiee, and then used in various manufacturing processes.the cellulose can be converted into chemically to produce the full range of cellulose derivatives (acetate cellulose, carboxymethylcellulose, etc.). the patent protects the results of our work have developed the use of posidonia oceanica as a feedstock for the production of a cellulose based products and for the production of a variety of cellulosic materials.these products may be manufactured from cellulose extracted from posidonia oceanica or directly from the crude plant without going through the steps of separation and purification of cellulose. these methods are important production economic benefits.
