Title: Process for the production of cellulose or cellulose containing material having acid properties
IPC: C08B15/04
Filed: 1954-04-05
Abstract: Oxycellulose is obtained by passing nitrogen dioxide or a gaseous mixture containing nitrogen dioxide through cellulose or cellulose-containing material at such a rate that substantially no nitration or parchmentation of the cellulose takes place, the pressure or partial pressure of nitrogen dioxide in the gas being subatmospheric and correlated with the temperature so as to render the cellulosic material alkali-soluble.  Mixtures of nitrogen dioxide with inert gases, e.g. air, oxygen and nitrogen, may be employed. The reaction may be effected at 45-65 DEG  C.  The cellulosic material may be oxidized in the form of fibres, flakes, wadding or paper.  In the case of fibres or flakes treatment may be effected in conical or other shaped chambers employing the suspension or turbulence-bed techniques, the fibres or flakes being kept in suspension by the upflowing gases.  If desired, several chambers may be arranged in series, the upflow gas velocities increasing progressively to expel the oxidized cellulose from one chamber into the next.  Creped paper may be treated in rolls.  Deacidification of the oxycellulose may be effected by passing inert gases through the material, or alternatively superheated steam may be so employed at reduced pressure and at 50-70 DEG  C., and, in either case, fluctuating pressures may be employed.  The steam effluent may be rectified to remove nitric acid, superheated and recirculated, the nitric acid so recovered being thermally degraded to yield a nitrogen dioxide-oxygen mixture which is then employed as the gaseous oxidizing agent.  The oxycellulose in the form of fibres, flakes, wadding or paper may be employed for the dealkalization and cleaning of gases, and liquids, the trace-purification of coal and synthesis gases, for filtering tobacco smoke, for preparing spinning and casting solutions for the manufacture of fibres and films and for the manufacture of artificial catgut and wound tampons.
