| titleOfInvention | The Preparation method and use of the cellulose sorbing material of sulfonic acid funtionalized |
| abstract | A kind of preparation method of the cellulose sorbing material of sulfonic acid funtionalized, including：Amino aromatic sulphonic acid and acid anhydrides will be contained in inert aprotic solvent, under Louis acid catalysis, the ring-opening reaction of ammonifying base and acid anhydrides is issued in 90~120 DEG C, makes to be connected with carboxyl in the molecule of aromatic sulphonic acid；By the material of the aromatic sulphonic acid for being connected with carboxyl and containing cellulose structure of above-mentioned generation, in inert aprotic solvent, bronsted acid catalyst is added, it is esterified using carboxyl and the primary hydroxyl in cellulosic structure, in the presence of inertia water entrainer, the water that esterification generates is taken away reaction system, keeps esterification complete by water entrainer azeotrope with water item；By distillation, water entrainer, inert aprotic solvent are recycled；Esterification products after recycling design are obtained into the cellulose sorbing material of sulfonic acid funtionalized through alkali neutralization, washing, filtering, drying.The present invention has production technology simple, and raw material sources are extensive, and production cost is too low, the features such as can be recycled. |
