    Abstract: A process for preparing a polymer having a 2,5-furandicarboxylate moiety within the polymer backbone and having a number average molecular weight of at least 10,000 (as determined by GPC based on polystyrene standards) includes a first step wherein a prepolymer is made having the 2,5-furandicarboxylate moiety within the polymer backbone, followed in a second step by a polycondensation reaction. In the first step a 2,5-furandicarboxylate ester is transesterified with a compound or mixture of compounds containing two or more hydroxyl groups, in the presence of a tin(IV) based transesterification catalyst. In the second step at reduced pressure and under melt conditions the prepolymer prepared in the first step is polycondensed in the presence of a tin (II) based polycondensation catalyst until the polymer is obtained. This polymer may then be subjected to Solid State Polycondensation. Polymers so produced may have a 2,5-furandicarboxylate moiety within the polymer backbone, and having a number average molecular weight of at least 20,000 (as determined by GPC based on styrene standards), and an absorbance as a 5 mg/mL solution in a dichloromethane:hexafluoroisopropanol 8:2 at 400 nm of below 0.05.

    Abstract: 2,5-Furandicarboxylic acid and methyl acetate are prepared in a continuous process by introducing a 5-methoxymethylfurfural-containing feedstock, an oxygen-containing gas, an oxidation catalyst and an acetic acid-containing solvent into a reactor; allowing 5-methoxymethylfurfural to react with oxygen and acetic acid in the presence of the oxidation catalyst to yield 2,5-furandicarboxylic acid as main product and methyl acetate; withdrawing 2,5-furandicarboxylic acid-containing product from the reactor and recovering 2,5-furandicarboxylic acid product; and withdrawing a vaporous stream containing methyl acetate from the reactor.

    Abstract: A substituted benzene derivative is prepared in a process, which includes reacting a furan derivative of formula (I): wherein R is an alkyl group, with an olefin of formula (II): R1—CH═CH—R2  (II) wherein R1 and R2 are the same or different and independently are selected from the group consisting of hydrogen, —CN, —CHO and —COOR3, wherein R3 is selected from hydrogen or an alkyl group, or R1 and R2 together form a —C(O)—O—(O)C— group, with the proviso that R1 and R2 are not both hydrogen, to produce a bicyclic ether; and dehydrating the bicyclic ether to obtain a benzene derivative. The benzene derivative thus obtained can suitably be converted to a benzene carboxylic acid compound by oxidation.

    Abstract: A process for the conversion of solid lignocellulosic material containing hemicellulose, cellulose and lignin, includes (a) hydrolyzing, at a temperature equal to or less than 40° C. at least part of the hemicellulose and at least part of the cellulose of the solid lignocellulosic material with an aqueous hydrochloric acid solution, containing in the range from equal to or more than 40.0 wt. % to equal to or less than 51.0 wt. % hydrochloric acid, based on the combined weight amount of water and hydrochloric acid in the aqueous hydrochloric acid solution; yielding a hydrochloric acid-containing, aqueous hydrolysate solution; (b) separating the hydrochloric acid-containing, aqueous hydrolysate solution from the lignin; and (c) heating at least part of the hydrochloric acid-containing, aqueous hydrolysate solution to a temperature equal to or more than 60° C., yielding a product solution containing 5-(chloromethyl)furfural, and extracting the 5-(chloromethyl)furfural from the product solution into an extraction solvent.
