Abstract

By the method the lignin-containing, or lignin sulphonic acid-containing, respectively, initial raw materials are heated, and the desired substances produced under the effect of the heat during the evaporation of the solid components of the initial raw materials are evaporated. Boundary conditions, are maintained necessary for the separation of the unacceptable substances, the conditions being unusual for turning out the end products from the solid components of the initial raw materials, but are not harmful to them. 11 claims
