The invention is directed to bio-oil fractions compositions comprising anhydro sugars and acetic acid obtained from bio-oils when subjected to polar solvent mixtures, to the process for the preparation of a bio-oil fractions composition, the uses thereof, as well as a desiccant herbicide and a crop insecticide comprising said bio-oil fractions composition. Further, the invention is also directed to a method for preparing a dispersion composed of an oil phase and a non-oil phase, by contacting a bio-oil with a polar solvent, and to a method for extracting a bio-oil fractions composition and a pyrolytic lignin from the dispersion.
A bio-oil fractions composition, comprising anhydro sugars and acetic acid wherein a weight proportion of anhydro sugars to acetic acid is from 0.8-1.5.
A pyrolytic lignin comprising from 15-20% phenols and from 12-16% benzaldehydes.
