The invention relates to a process for the preparation of acetals from carbon dioxide. The invention also relates to a mixture of phosphorus containing ligands comprising least one polydentate ligand and at least one monodentate ligand. Further, the invention also relates to the use of mixtures comprising at least one polydentate ligand and at least one monodentate ligand in transition metal complexes for the preparation of acetals.

Process for the production of acetals from carbon dioxide

The present invention relates to a process for the dimerization of alkenes comprising (1) providing a gas stream comprising one or more alkenes; and (2) contacting the gas stream provided in (1) with a catalyst for obtaining a mixture M1 comprising one or more dimerization products of the one or more alkenes, wherein the catalyst in (2) comprises a zeolitic material having a framework structure type selected from the group consisting of MOR, BEA, FER, MFI, TON, FAU, and mixtures of two or more thereof, wherein the framework structure of the zeolitic material comprises YO, wherein Y stands for one or more tetravalent elements.

Catalyzed process for the dimerization of alkenes

Provided herein is a process for preparing furan-2,5-dicarboxylic acid. The process includes the following steps: (A-1) preparing a starting mixture comprising one, two or more carbohydrate compounds selected from the group consisting of: hexoses, oligosaccharides comprising hexose units, and polysaccharides including hexose units, and as a solvent or as a co-solvent for the carbohydrate compounds an amount of one or more carboxylic acid esters of a formula (II) and (A-2) subjecting the starting mixture to reaction conditions so that at least one of the one, two or more carbohydrate compounds reacts, and a fraction of the amount of one or more carboxylic acid esters of formula (II) is hydrolyzed, resulting in a mixture including 5-(hydroxymethyl)furfural and/or the one or more HMF esters of a formula (I), one or more carboxylic acids of a formula (III) and a remaining fraction of the amount of one or more carboxylic acid esters of formula (II).

Process for preparing furan-2,5-dicarboxylic acid

Provided herein is a process for preparing a mixture including 5-(hydroxy-methyl)furfural (HMF) and one or more HMF esters of formula (I), the process including the following steps: (A-1) preparing or providing a starting mixture which includes one, two or more carbohydrate compounds and as the solvent or as a co-solvent for the carbohydrate compounds an amount of one or more carboxylic acid esters of formula (II); (A-2) subjecting the starting mixture to reaction conditions so that at least one of the one, two or more carbohydrate compounds reacts, and a fraction of the amount of one or more carboxylic acid esters of formula (II) is hydrolyzed, so that a mixture results that includes 5-(hydroxy-methyl)furfural and/or the one or more HMF esters of formula (I), one or more carboxylic acids of formula (III) and a remaining fraction of the amount of one or more carboxylic acid esters of formula (II).

Process for preparing a mixture comprising 5-(hydroxymethyl) furfural and specific HMF esters

Catalytic process for preparing an &#x3b1;,&#x3b2;-ethylenically unsaturated carboxylic acid salt, comprising reacting an alkene and carbon dioxide in the presence of a carboxylation catalyst and releasing the &#x3b1;,&#x3b2;-ethylenically unsaturated carboxylic acid salt with a base, the carboxylation catalyst being a transition metal complex, which comprises a structurally constrained bidentate P,X ligand, wherein X is selected from the group consisting of P, N, O, and carbene, the P and X atom are separated by 2 to 4 bridging atoms, and wherein the bridging atoms are part of at least one 5- to 7-membered cyclic substructure. A further catalytic processes for preparing &#x3b1;,&#x3b2;ethylenically unsaturated carboxylic acid derivatives from COand an alkene is provided.
