    Abstract: Thermolytic cracking of formamide (I) to HCN and H2O is carried out by introducing superheated (I) gas at 300-480 deg.C under reduced pressure of 1-350 mbar and with 0.1-10 vol.% air into a reactor with a nest of tubes and passing at 450-590 deg.C and an average dwell time of 0.01-0.25 s over highly sintered mouldings, consisting of 50-100 wt.% Al2O3 and 50-0 wt. % SiO2 or over Cr-Ni stainless steel mouldings, which are resistant to high temp. corrosion. (I) is introduced at 300-400 deg.C and 50-150 mbar with 1.0-3.0 vol.% air; and cracked at 500-540 deg.C witha dwell time of 0.01-0.15 s.. The mouldings consist of 85-95 wt.% Al2O3 and 15-5 wt.% SiO2; or of 18-21 wt.% Cr, 9-13 wt.% Ni, 0-3 wt.% and the rest Fe.
