| titleOfInvention | METHOD FOR PROCESSING LIGNOCELLULOSE MATERIALS |
| abstract | 1. A method of cooking a fibrous lignocellulosic material, which includes the steps of:! (a) heating the material in the presence of an oxalic acid derivative and! (b) processing the material that is heated in step (a) into cellulose. ! 2. The method according to claim 1, in which the oxalic acid derivative is a compound of formula (I):! ! in which R1 and R2 independently represent hydroxyl, an oxygen atom, a halide, a substituted or unsubstituted amine, an -OR3 group or a side chain of the formula (II):! ! in which R3 and R4 independently represent a branched or unbranched, cyclic or linear, saturated or unsaturated, substituted or unsubstituted alkyl having from 1 to 10 carbon atoms; and! in which both radicals R1 and R2 cannot be hydroxyl. ! 3. The method according to claim 2, in which R1 is OR3. ! 4. The method according to claim 3, in which R2 means OR3. ! 5. The method according to claim 4, in which the oxalic acid derivative is diethyl oxalate. ! 6. The method according to claim 4, in which the oxalic acid derivative is dimethyl oxalate. ! 7. The method according to claim 1, in which the material is a dry mass, and in which the oxalic acid derivative is present in an amount of less than about 6% of the dry mass of the material. ! 8. The method according to claim 1, in which the material is a dry mass, and in which the oxalic acid derivative is present in an amount of less than about 5% of the dry mass of the material. ! 9. The method according to claim 1, in which the material is a dry mass, and in which the derivative of oxalic acid is present in an amount of approximately between 0.05 and 5% of the dry weight of the material. ! 10. The method according to claim 1, in which the material is a dry mass, and in which the derivative |
