Abstract
Implementations of the disclosed subject matter provide a process for converting biomass into furfural. The process may include subjecting a pentosan-containing biomass material to an acid catalyzed digestion process in a digestion vessel to produce a digested product stream comprising C5-carbohydrates and solids comprising cellulose. The digested product stream may be separated into a liquid product stream and a solid product stream comprising lignin and cellulose. The solids product stream may be contacted with water and an organic solvent, thereby converting at least part of the lignin to a phenolic solvent. The C5-carbohydrate in the liquid product stream may be subjected to a dehydration reaction in the presence of an acid catalyst and a biphasic mixture comprising an aqueous phase and a water-immiscible organic phase, wherein the water-immiscible organic phase includes at least a portion of the phenolic solvent, to produce furfural or a furan derivative.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
