    Abstract: A process includes the following steps: a) converting a solid material containing hemicellulose, cellulose and lignin, by: (i) hydrolyzing at least part of the hemicellulose of the solid material with a first aqueous hydrochloric acid solution, yielding a remaining solid material and a hydrochloric acid- containing, aqueous, first hydrolysate product solution; (ii) hydrolyzing at least part of the cellulose of the remaining solid material with a second aqueous hydrochloric acid solution, yielding a residue and a hydrochloric acid-containing, aqueous, second hydrolysate product solution; (b) forwarding to step (c) a, hydrochloric acid-containing, aqueous intermediate product solution comprising: a part of or the whole of the hydrochloric acid-containing, aqueous first and/or second hydrolysate product solution of step (a); and (c) heating at least part of the hydrochloric acid-containing, aqueous intermediate product solution to yield a product solution containing 5-(chloromethyl)furfural, and extracting the 5-(chloromethyl)furfural from the product solution into an extraction solvent.

    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.

    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.
