A process is disclosed for fractionating lignocellulosic materials fast-pyrolysis oils to produce phenol-containing compositions suitable for the manufacture of phenol-formaldehyde resins. The process includes admixing the oils with an organic solvent having at least a moderate solubility parameter and good hydrogen bonding capability, the solvent extracting the phenol and neutral fractions from the oils. The organic solvent-soluble fraction containing the phenol and neutral fractions is separated from the mixture and admixed with water to extract water-soluble materials therefrom. The organic solvent-soluble fraction is then separated from the water fraction and admixed with an aqueous alkali metal bicarbonate solution to extract strong organic acids and highly polar compounds from the solvent fractions. Finally, the residual organic solvent-soluble fraction is separated, and the organic solvent is removed therefrom to produce the phenol-containing compositions.
