Abstract

Method for the manufacture of hydrocyanic acid, characterized in that it is carried out by means of the reaction of ammonia, methane, nitrogen and oxygen, in the presence of a catalyst constituted by platinum networks or their alloys, at a temperature of the range of 1100 to 1200º C , starting from a gaseous mixture, of composition corresponding to the molar ratios comprised in the range defined by the following values; O2/O2 + N2 from > 0.21 to 0.35 O2 + N2/NH3 from 6 to 2 O2 + N2/CH4 from 6 to 1.6 CH4/NH3 from 1.3 to 1.0, and subjecting said gaseous mixture, before it enters the reactor, to a preheating comprised in the range from 200 to 400º C.
