| Zusammenfassung: | Process for preparing hydrocyanic acid, which comprises catalytic dehydration of gaseous formamide to give a product mixture comprising hydrocyanic acid, water, formamide, ammonia, CO and high boilers, separation of the product mixture by condensation of a condensate comprising water, formamide, high boilers and possibly ammonia and hydrocyanic acid from the product mixture obtained and partial or total recirculation of the condensate into a heat exchanger located downstream of the reactor. |
