Abstract

The present invention refers to a method for manufacturing a phosphorylated lignin which is soluble in water at a pH range of 2 to 14. Said method comprises the efficient phosphorylation of lignin preventing the formation of undesired species, which leads to an outstanding water solubility at neutral and acidic conditions, and, preferably, the separation of the water-soluble phosphorylated lignin from the reaction medium, wherein said separation comprises acid precipitation and/or ultrafiltration and drying under specific conditions. The invention also refers to a phosphorylated lignin that is water-soluble at a pH of 2 to 14, preferably obtained by the method of the invention.
