The invention relates to a method for producing lignin particles, comprising the steps of: a) extracting lignin from a lignincontaining starter material, using a mixture that comprises at least one organic solvent and water, and b) precipitating the lignin in the solution from step a).

Production of lignin particles

A method for working up an aqueous, alkaline-alcoholic and lignin containing solution via nanofiltration, wherein a permeate and a retentate are obtained, which permeate is an aqueous, lignin-starved solution and which retentate is an aqueous lignin-enriched solution.

Method for working up an aqueous lignin containing solution

A process for separating oxygenous organic compounds from aqueous media by liquid-liquid extraction with an organic extraction agent. In order to enable the satisfactory and selective separation of the organic compounds without remarkable amounts of extraction agent remaining dissolved in the raffinate and without microorganisms possibly present in the aqueous media being impaired, an extraction agent is used that contains up to 100% by mass of at least one aldehyde including 4 to 20 carbon atoms.
