VERBESSERTES VERFAHREN ZUR HERSTELLUNG VON BLAUSÄURE DURCH KATALYTISCHE DEHYDRATISIERUNG VON GASFÖRMIGEM FORMAMID - DIREKTHEIZUNG

摘要

Process for preparing hydrocyanic acid by catalytic dehydration of gaseous formamide, wherein the dehydration of formamide is coupled with an exothermic reaction by the reactor used in the dehydration comprising two separate fluid paths which are separated by a common reactor wall, with one fluid path being provided for the dehydration of formamide and the second fluid path being provided for the exothermic reaction.
