TREATMENT OF PULP TO PRODUCE MICROCRYSTALLINE CELLULOSE
Eljárás mikrokristályos cellulóz előállítására, amelynek során pulpotelegendő mennyiségű aktív oxigénnel savas közegben egylépcsőseljárásban hidrolizálnak és kinyerik a mikrokristályos cellulózt,amikor is a kinyert mikrokristályos cellulóz színvilágossági foka (L*)nagyobb, mint a kiindulási anyagkén...

| description | Eljárás mikrokristályos cellulóz előállítására, amelynek során pulpotelegendő mennyiségű aktív oxigénnel savas közegben egylépcsőseljárásban hidrolizálnak és kinyerik a mikrokristályos cellulózt,amikor is a kinyert mikrokristályos cellulóz színvilágossági foka (L*)nagyobb, mint a kiindulási anyagként használt pulp szín-világosságifoka (L*). Ó
In one embodiment of the invention is disclosed a process for the production of microcrystalline cellulose comprising hydrolyzing pulp with a sufficient amount of active oxygen in an acidic environment in a one step process; and recovering the microcrystalline cellulose; wherein said recovered microcrystalline cellulose has a color lightness (L*) greater than the color lightness (L*) of the pulp starting material. |
