A hydrogenated Diels-Alder adduct of the formula (III) a hydrogenated Diels-Alder adduct of the formula (IV) anda lactone compound of formula (V) are disclosed and described.

Hydrogenated Diels-Alder adducts and lactone compounds

A benzene compound is prepared by reacting a furan compound to produce an unsaturated bicyclic ether having an unsaturated carbon-carbon bond; hydrogenating the unsaturated carbon-carbon bond in the unsaturated bicyclic ether to produce a saturated bicyclic ether; and dehydrating and aromatizing the saturated bicyclic ether to produce the benzene compound.

Process for the preparation of a benzene compound

The present invention refers to a process for production of a mixture including 2,4-furandicarboxylic acid (2,4-FDCA) and 2,5 furandicarboxylic acid (2,5-FDCA) through the disproportionation route, using as base compounds oxidation products of furfural. This invention also relates to a process for production of 2,4-FDCA as a result of a disproportionation route and the use of 2,4-FDCA as a monomer or comonomer to synthesize esters or any compounds which can generate macromolecules, such as polyesters.

&bgr;-Ketoesters and their enamines derived from alcohols or polyols are suitable for stabilizing polymers, and are represented by formulae: A&lsqb;(O&mdash;CHR &mdash;Z&mdash;CHR ) &mdash;O&mdash;CO&mdash;CHR &mdash;CO&mdash;R &rsqb; and A&lsqb;(O&mdash;CHR &mdash;Z&mdash;CHR ) &mdash;O&mdash;CO&mdash;CR &boxH;C(&mdash;NHR )&mdash;R &rsqb; , wherein: A is the residue of an alcohol or polyol selected from hydroxyalkanoic acid esters, sugars and their glycosides, sugar alcohols, sugar acids and their esters, and oligosaccharides; m is an integer number from 0 up to 6; n is a number from 1 up to the total number of hydroxyl groups in the polyol; R is hydrogen, C -C alkyl, C -C alkenyl or cycloalkyl (alkyl) or C -C aryl or aralkyl; R is hydrogen, C -C alkyl, C -C hydroxyalkyl or C -C alkenyl; R is C -C alkyl, alkoxy or alkylamino, C -C alkenyl, alkanoylmethyl, alkoxycarbonylmethyl or cycloalkyl(alkyl), C -C aryl, aryloxy, arylamino, aralkyl, aralkoxy or aralkylamino, or C -C aroylmethyl, aryloxycarbonylmethyl or arylcarbamoylmethyl; R and R are independently hydrogen or methyl; and Z is a direct bond, CH , CHOH, CH&mdash;O&mdash;CO&mdash;CHR &mdash;CO&mdash;R or O&mdash;CO&mdash;CR &boxH;C(&mdash;NHR )&mdash;R .

&bgr;-ketoesters for use as polymer stabilizers

Natural cyclic polyalcohols such as polyfructoses and, dehydration products of sugar alcohols can be used for stabilising thermoplastic polymers, at a ratio of 0.001-5 phr of polyol with respect to the polymer. The cyclic polyol is in particular inulin or sorbitan. The polymer to be stabilised is in particular PVC, PE, PP or a halogenated rubber.
