    Abstract: A process for the preparation of nitro compounds by reacting an organic substrate with nitrogen dioxide either in the presence of oxygen or under such conditions that the nitrogen dioxide/organic substrate ratio is less than 1 by mole. The reaction may be conducted in the presence of an imide compound such as N-hydroxyphthalimide and the organic substrate includes (a) aliphatic hydrocarbons, (b) alicyclic hydrocarbons, (c) nonaromatic heterocyclic compounds having ring-constituent carbon atoms bonded to hydrogen atoms, (d) compounds bearing aromatic rings and carbon-hydrogen bonds adjacent to the rings, (e) carbonyl compounds bearing carbon-hydrogen bonds adjacent to the carbonyl groups, and so on. This process enables efficient nitration of organic substrates even under relatively mild conditions.

    Abstract: Process for the production of a chemical compound from a carbon dioxide starting material, comprising the steps of a) providing a feed stream consisting mainly of carbon dioxide; b) electrolysing in an electrolysis stage the carbon dioxide in the feed stream to a first gas stream containing carbon monoxide and a second gas stream containing oxygen, wherein the molar ratio between carbon monoxide and oxygen is about 1:0.5 in an electrolysis stage; c) adjusting the composition of the first gas stream or the second gas stream or both gas streams to include carbon dioxide, either by operating at less than full conversion of CO 2 or by sweeping one or both gas streams with a gas containing CO 2 or by at some stage between the electrolysis cell and the oxidative carbonylation reactor diluting one or both gas streams with a gas containing CO 2 ; all while maintaining an overall molar ratio of carbon monoxide to oxygen of about 1:0.5; and d) introducing the first and second process stream into a reaction stage and reacting the first and second process stream combined or in succession with a substrate to the chemical compound by means of an oxidative carbonylation reaction with the carbon monoxide and oxygen contained in the process feed stream.
