ABSTRACT:
Tall oil obtained by splitting sulphate soap with an acid, and which still contains acid splitting liquid residues after removal of splitting liquid, is subjected to a lignin-removing operation by drying the tall oil to free it from an additional quantity of splitting liquid, and thereafter separating lignin in solid form, together with an acid residue of salt crystals, from the tall oil thus dried.
