This invention concerns a method for the production of at least a furanic compound having at least one aldehyde function and electrical power, by oxidizing at least a furanic compound having at least one hydroxyl function.

Selective oxidation of furan based alcohols via electro-generative process

Provided is a process for the production of an aromatic compound comprising at least two amine functions, comprising reacting an aromatic compound having at least one hydroxyl function and at least one aldehyde function with a second reactant having an amine function, in the presence of a reductant agent and a catalyst comprising at least one metal element in elemental form and/or at least one metal oxide.

Process for production of aromatic compounds comprising at least two amine functions

An amorphous catalyst support comprising at least a first oxide selected from the group consisting of: silica, germanium oxide, titanium oxide, zirconium oxide or mixtures thereof, preferably silica gel beads or diatomaceous earth; a group 3 metal oxide; and anions in an amount not greater than 10% by weight of the catalyst support; wherein the group 3 metal oxide is incorporated in the first oxide structure at the molecular level. The catalyst support is prepared by (a) mixing the first oxide, with an anhydrous source of the group 3 metal oxide, and water, at a pH above 11, thus forming a suspension, (b) washing the catalyst support with water, (c) separating the catalyst support from the water, and (d) optionally drying and/or calcining the catalyst support. A catalyst based on such a support has improved catalytic properties.

Catalyst support and process for the preparation thereof

The present invention refers to an aqueous hydrogen peroxide solution having a hydrogen peroxide concentration [HO] expressed as % by weight of the solution and an apparent pH of from pHto pH, such that pH=3.45&#x2212;0.0377&#xd7;[HO], and pH=3.76&#x2212;0.0379&#xd7;[HO]. The present invention also relates to a process for the preparation of said hydrogen peroxide solution and the use of said solution in a process for the epoxidation of olefins.
