Abstract
A process for the air oxidation of hydrogen cyanide to isocyanic acid in the presence of a solid catalyst utilizing adiabatic conditions and controlling temperatures by the proportion of inert gas.
Claims8
A process for oxidation of hydrogen cyanide to isocyanic acid which comprises passing a gas feed stream of hydrogen cyanide, oxygen and inert gas under adiabatic conditions in contact with a solid catalyst effective to promote the reaction of hydrogen cyanide and oxygen to form isocyanic acid, the proportion of oxygen being at least one-half mole per mole of hydrogen cyanide, the reaction temperature at the catalyst being about 500.degree.-700.degree. C., and said temperature being controlled by the proportion of inert gas in said gas feed stream.
