    摘要: An apparatus for the recovery of a halogen or pseudohalogens from a halide compound in solution; wherein the apparatus includes an electrochemical cell including, an electrode assembly including at least a first and second electrodes in communication with a controller for providing a current to at least two of the electrodes; wherein, upon delivery of a predetermined voltage, the halide compound is oxidised at one or more of the electrodes to form a halogen corresponding to the halide in solution whereupon the halogen is deposited on said one or more electrode upon completion of oxidation.

    摘要: A method for the treatment of a lignin-containing material such as wood pulp, bagasse and other plant-derived materials, comprising contacting the lignin-containing material with an ionic liquid to extract the lignin therefrom. The ionic liquid is suitably a substituted or unsubstituted imidazolium, triazolium, pyrazolium, pyridinium, pyrrolidinium, piperidinium, ammonium, phosphonium or sulfonium salt of a substituted or unsubstituted aryl sulfonate, such as an ionic liquid salt of a xylene sulfonate.
