(FR) ACIDE CYANHYDRIQUE OBTENU A PARTIR DE FORMAMIDE
Abstract
(DE) Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Blausäure (HCN) durch katalytische Dehydratisierung von gasförmigem Formamid in einem Reaktor, der eine innere Reaktoroberfläche aus einem Stahl enthaltend Eisen sowie Chrom und Nickel aufweist, sowie einen Reaktor zur Herstellung von Blausäure durch katalytische Dehydratisierung von gasförmigem Formamid, wobei der Reaktor eine innere Reaktoroberfläche aus einem Stahl enthaltend Eisen sowie Chrom und Nickel aufweist und die Verwendung des erfindungsgemäßen Reaktors in einem Verfahren zur Herstellung von Blausäure durch katalytische Dehydratisierung von gasförmigem Formamid.
(EN) The invention relates to a method for producing hydrocyanic acid (HCN) by means of catalytic dehydration of gaseous formamide in a reactor having an inner reactor surface consisting of a steel-containing iron, chromium and nickel. The invention also relates to a reactor for producing hydrocyanic acid by means of catalytic dehydration of gaseous formamide, said reactor having an inner reactor surface consisting of a steel-containing iron, chromium and nickel. The invention further relates to the use of the inventive reactor in a method for producing hydrocyanic acid by means of catalytic dehydration of gaseous formamide.
(FR) La présente invention concerne un procédé pour préparer de l'acide cyanhydrique (HCN) par déshydratation catalytique de formamide gazeux dans un réacteur qui présente une surface intérieure faite d'un acier qui contient du fer, du chrome et du nickel. L'invention a également pour objet un réacteur pour préparer de l'acide cyanhydrique par déshydratation catalytique de formamide gazeux, le réacteur présentant une surface intérieure faite d'un acier qui contient du fer, du chrome et du nickel, et l'utilisation du réacteur de l'invention dans un procédé pour préparer de l'acide cyanhydrique par déshydratation catalytique de formamide gazeux.
