Abstract
The present invention is a method for producing a pulp from a fibrous lignocellulose material or source using a treatment or pretreatment step which exposes the material to oxalic acid derivatives, particularly dialkyl ester derivatives, particularly in the vapor phase. Once treated, the material may be refined using any one of the several pulping methods to produce a final pulp product and the production of the product is accompanied by strength increases in paper made from the pulp and energy savings in making the pulp, hi addition the treatment or pretreatment produces a soluble carbohydrate source and other components (e.g. acetic acid, other wood components) for further product development. In certain cases a pulp product is not produced and all of the carbohydrate present in the lignocellulose is converted into soluble sugars.
