    摘要: The invention describes solutions containing cellulose and a method of dissolving lignocellulosic materials. In the method, the lignocellulosic material is contacted with a conjugate acid, formed by a strong organic base and a weaker acid, under conditions which are conducive to at least a partial dissolution of the cellulosic components of the lignocellulosic material. It has been found that it is possible to recover at least a portion of the dissolved part of the lignocellulosic material by at least partial dissociation of the conjugate acid. Furthermore it is possible to recover at least a portion of the dissociated organic base and the acid, to form a conjugate acid of the recovered base and acid, and to recycle it for use in the first steps of the method.

    摘要: The invention relates to a process for fibrillating lignocellulosic material wherein the process comprises treating lignocellulosic material with ionic liquid and recovering basically intact fibres of said lignocellulosic material. Another object of the invention is to provide an activated and/or basically intact fibre wherein the lignocellulosic material is treated with ionic liquid and a basically intact fibre of said lignocellulosic material is recovered. The invention further relates to the use of the basically intact fibre of the invention in the production of bio-based materials, preferably bio-plastics, more preferably conductive polymers, stimuli-responsive polymers, bio-based polymer composites, ceramics, fabrics, or elastomers. A process for producing paper, board, pulp or the like from fibers of lignocellulosic material which have been treated with ionic liquid and recovered as basically intact fibres is also enclosed.
