Processes and reactor systems for biomass conversion are described. A continuous process for the conversion of carbohydrate-containing feed material into furanic compounds comprises a reaction step comprising subjecting said feed material to reaction conditions in a reaction medium comprising two immiscible liquid phases, including a reactive phase and an extractive phase, and a Brønsted acid as catalyst, wherein the reaction medium comprises a solid component comprising at least a part of a carbohydrate-containing fraction of said feed material.

The invention relates to a method for preparing a compound comprising two phenyl groups by reacting a bisfuranic compound with a dienophile; and to such compounds.

Preparation of phenyl compounds

The present invention is directed to a method for preparing a final phenolic product from biomass comprising the steps of providing a furanic compound obtainable from biomass; reacting the furanic compound with a dienophile to obtain a phenolic compound; reacting the phenolic compound further to obtain the final phenolic product.

Method to prepare phenolics from biomass

The invention is directed to a method for preparing a phenolic compound comprising reacting a furanic compound with a dienophile in the presence of a catalyst comprising yttrium.
