The present invention relates to catalytic synthesis of furan derivatives from alkoxymethylfurfural ethers or acyloxymethylfurfural esters. More particularly, the invention pertains to furan derivatives obtained by use of a multifunctional catalyst system to carry out both hydrogenation of furan starting material and hydrolysis of the reduced furan derivative in a single reaction. The process allows recovering and recycling of alcohol or acid from the reaction product.

Method for the manufacture of organic acid esters of 5-hydroxymethylfurfural by reacting a glucose-containing starting material with an organic acid or its anhydride in the presence of a catalytic or sub-stoechiometric amount of acid catalyst. The catalysts are heterogeneous or homogenous and may be employed in a continuous flow fixed bed reactor. The esters can be applied as a fuel or fuel additive and as starting materials for the synthesis of monomers for polymerisation reactions.

acid-miscible organic solvent, (e.g., ethyl acetate). A soluble hemicellulose and lignin enriched fraction is obtained separately from a cellulose pulp enriched fraction and lignin is removed from the soluble hemicellulose fraction. The soluble hemicellulose and lignin enriched fraction is subjected to liquid/liquid separation to obtain an aqueous phase enriched in C5 sugars and C6 sugars and reduced in content of acetic acid. The syrup is suitable for fermentation. The process also produces fractions of organic-insoluble lignin, organic-soluble lignin, and acetate salts.

Method for the manufacture of organic acid esters of 5-hydroxymethylfurfural by reacting a fructose or glucose-containing starting material with an organic acid or its anhydride in the presence of a catalytic or sub-stoechiometric amount of solid acid catalyst. The catalysts are heterogeneous and may be employed in a continuous flow fixed bed reactor. The esters can be applied as a fuel or fuel additive.
