<p>A method of aminophenols production and/or their derivatives is commenced by reaction of water and gas containing carbon monoxide and components intensifying the reactant contact such as solvent, a catalyst of the semiphase transfer with nitrophenols or nitrosophenols, optionally derivatives thereof, at temperature from 80 to 240 degrees Celsius and pressure ranging from 0,15 to 30 Mpa; in an alk. medium during a catalyst reaction of sulphur and/or compounds thereof with a molar weight from 32 to 90 gmol-1, preferably sulphuretted hydrogen and carbonsulphide or compounds thereof with at least one vanadium compound in a total amount ranging from 0,2 to 12 percent by weight, in respect to the initial nitrophenols or nitrosophenols or derivatives thereof. The initial nitro- and nitrosocompounds or derivatives thereof-to-water molar ratio is ranging from 1 to 30. The said method is usable in the chemical industry, especially in production of intermediates of pharmaceutical compositions, antioxidants, pesticides, antioxidants and developers.</p> |
