Abstract
Process for preparing hydrocyanic acid by catalytic dehydration of gaseous formamide in at least one main reactor and a downstream after-reactor and also the use of an after-reactor in a process for preparing hydrocyanic acid by catalytic dehydration of gaseous formamide.
Claims15
A process for preparing hydrocyanic acid by catalytic dehydration of gaseous formamide, comprising
- (i) catalytic dehydration of gaseous formamide in at least one main reactor to form an intermediate gaseous reaction product, where the conversion of formamide at an outlet from the at least one main reactor is at least 95%, based on the formamide used, and
- (ii) introduction of the intermediate gaseous reaction product into an after-reactor at an entry temperature of from 350 to 700° C., where the after-reactor comprises internals or beds composed of steel and is operated adiabatically.
