Abstract Kraft lignin has high dispersity and low reactivity. This study aimed to obtain more homogeneous modified chemical fractions from the application of fractionation methods using organic solvents acid precipitation. Organic used were ethyl acetate, ethanol, methanol acetone. The pHs tested 9, 7, 5, 3 1, by adding hydrochloric acid. characterized acid-soluble insoluble lignin, carbohydrates, ashes, elemental analysis Py-GC/MS. All obtained in both showed higher carbon contents, purity lower S/G ratio than corresponding initial materials, characteristics that are very favorable for biorefinery. Acetone-soluble (sequential) pH 1 (one-step) precipitated most promising fiber production. Fractions soluble acetate at appear be appropriate applications require good oxidative properties. ethanol (one-step), acetone 9 5 ones allow better substitution obtaining bioproducts. not commercial interest due their yield.
