Title:
PROCESS FOR THE PREPARATION OF NITRO COMPOUNDS AND METHOD FOR THE REMOVAL OF NITROGEN DIOXIDE
Document Type and Number:
WIPO Patent Application WO/2000/069803
Kind Code:
A1
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.
