标 题:Synthesis of Diacids, Dialdehydes, or Diamines from THF-Diols
发明人：STENSRUD KENNETH
权利人:ARCHER DANIELS MIDLAND CO
摘要:A simple and elegant chemical process for the synthesis of oxygenated products, such as acids and aldehydes, or other derivative products, such as amines and nitriles, of cyclic bifunctional molecules made from renewable, bio-based sources such as HMF and/or its reduction product, 2,5-bis(hydroxymethyl)-tetrahydrofuran (bHMTHF) is described. In general, the process involves: a) generating a tetrahydrofuran-2,5-diyl-bis(methylene)-bis(sulfonate) from bHMTHFs using a sulfonate; b) displacing nucleophilically at least a sulfonate leaving group from the tetrahydrofuran-2,5-diyl-bis(methylene)-bis(sulfonate) to form a THF-dinitrile; and either c) oxidizing the THF-dinitrile with an acid having a pKa of ≦0 to generate a di-acid, or d) reducing partially the THF-dinitrile to generate a di-aldehyde, or e) reducing fully the THF-dinitrile to generate a di-amine.

标 题:Synthesis of isohexide dicarbamates and derivatives thereof
发明人：STENSRUD KENNETH
权利人:ARCHER DANIELS MIDLAND CO; ARCHER DANIELS MIDLAND CO
摘要:Dicarbamates of the reduction products of 2-hydroxymethyl-5-furfural (HMF) and a method of preparing the same are described. The method involves reacting a mixture of an isohexide and a cynate salt in a non-aqueous solvent, with a miscible acid having a pKa of about 3.7 or less. The dicarbamates of HMF-reduction products can serve as precursor materials from which various derivative compounds can be synthesized.

标题 :Direct synthesis of bio-based alkyl and furanic diol ethers, acetates, ether-acetates, and carbonates
发明人：STENSRUD KENNETH; VENKITASUBRAMANIAN PADMESH
权利人:ARCHER DANIELS MIDLAND CO
摘要:A method of preparing a glycol mono-ether or mono-acetate, or carbonate involving either one of two pathways from alkylene glycols, HMF or its reduction derivative products (i.e., FDM, bHMTHFs), is provided. In particular, according to one pathway, the alkylene glycol, HMF or FDM, bHMTHFs are reacted with a dialkyl carbonate in the presence of a deprotonating agent, in substantial absence of an extrinsic catalyst, to produce an ether, and subsequently reacting the ether with an acid base. According to the other pathway, alkylene glycols are reacted with an acetate donor in the presence of an acid, base, to generate an alkylene mono-acetate, and etherified with a carbonate in the presence of a deprotonating agent.
