text: The fractionation process based on an initial Soxhlet extraction with the organic solvent followed by a membrane-mediated ultrafiltration was carried out in this study on a representative technical lignin (Protobind 1000), using 2-butanone (methyl ethyl ketone, MEK) as the extraction solvent (due to its industrial relevance and its favorable toxicological profile).
text: The mass fractionation results were compared with a further test (process B) carried out by fractionating the same technical lignin (Protobind 1000) in an aqueous solvent (ethanol/basic water 60:40 v/v) with a different first stage process (0.7 μm membrane microfiltration instead of the Soxhlet extraction), as we described in a previous work with different membranes.
