Hydrogen peroxide is produced in a reaction between carbon monoxide, oxygen, and water in the substantial absence of gaseous hydrogen in the presence of a solvent using a soluble palladium compound as a catalyst and employing an arsine or phosphine ligand.

Preparation of hydrogen peroxide

A process and accompanying catalyst for the hydroformylation of formaldehyde to glycol aldehyde is disclosed. The process features the utilization of (1) a class of transition metal phosphine-amide complexes, (2) a class of transition metal phosphine-amine complexes, and (3) mixtures of 1 and 2 as particularly suitable for use.

Process and accompanying catalysts for the hydroformylation of

An improved transition metal-phosphine-amide hydroformylation catalyst is disclosed having a substantially increased solubility in non-polar organic solvents, thereby preventing migration of the catalyst into the glycol aldehyde product during the hydroformylation process and subsequent separation operations, greatly facilitating and improving the catalyst separation and recycle operations.

Process and catalyst useful in the production of glycol aldehyde

A process for the preparation and purification of a glycol aldehyde intermediate which is later hydrogenated to ethylene glycol is disclosed. The process proceeds via the catalytic reaction of formaldehyde, carbon monoxide and hydrogen and utilizes a novel class of lipophilic rhodium phosphine amide catalysts and an effective solvent mixture, which enables efficient catalyst separation and recycle without the loss of a substantial amount of the expensive catalyst.

Process for the production of ethylene glycol through the

A process for converting a desired olefin to the corresponding olefin oxide, such as propylene oxide, and/or ketone comprising reacting a mixture of the olefin, thallic oxide, carbon dioxide and water in a substantially organic solvent-free reaction zone; withdrawing a product stream from the reaction zone, the stream comprising the olefin and ketone product; separating and collecting the olefin oxide and ketone product from the stream; contacting the reduced thallous values present in the mixture with molecular oxygen and an effective catalyst to back oxidize the thallous values to their original thallic form; separating and recycling back to the reaction mixture the regenerated thallic values.

Process for production of olefin oxides and ketones

A process for the production of alkylene carbonates, such as propylene carbonate, is disclosed. The process involves reacting the desired olefin with a thallic oxide or a weak acid thallic salt with carbon dioxide in an aqueous, organic solvent containing, halogen-free system.

Process for the production of alkylene carbonates and oxides

A process for the preparation of alkylene carbonates, particularly ethylene carbonate, by the reaction of the corresponding olefins with carbon dioxide in the presence of iodine or an iodide compound and an oxide or a weak acid salt of thallium (III). The thallium is reduced to the T1(I) form which may be oxidized back to the T1(III) form for reuse. Gold(III) oxide is also effective.
