Abstract

Procedimiento para preparar ácido cianhídrico mediante deshidratacion catalítica de formamida gaseosa, en el que la deshidratacion catalítica se lleva a cabo en un reactor tubular a un perfil particular de temperatura. Reivindicacion 1: Un procedimiento para preparar ácido cianhídrico por deshidratacion catalítica de formamida gaseosa en un reactor tubular, caracterizado porque la formamida gaseosa, que ha sido calentada a temperaturas que van de 330 a 400sC, es conducida al reactor tubular para formar un gas de proceso que contiene ácido cianhídrico gaseoso, agua y formamida que no ha reaccionado, en el que la temperatura del gas de proceso se aumenta a lo largo del reactor tubular en 0,25 hasta 0,75 K/cm..
