(FR) PROCÉDÉ DE PRODUCTION D'ISOCYANATES PAR OXYDATION ANODIQUE DE FORMAMIDES
Abstract
(DE)
Verfahren zur Herstellung von Isocyanaten R-NCO durch anodische Oxidation von Formamiden der allgemeinen Formel (I) worin R Wasserstoff oder einen beliebigen organischen Rest bedeutet, wobei die Elektrolyselösung neben dem Formamid (I) mindestens ein Leitsalz enthält.
(EN)
The invention relates to a method for the production of isocyanates R-NCO by anodic oxidation of formamides of the general formula (I), wherein R is hydrogen or an arbitrary organic radical, wherein the electrolytic solution comprises at least one conductor salt in addition to the formamide (I).
(FR)
L'invention concerne un procédé de production d'isocyanates R-NCO par oxydation anodique de formamides de formule générale (I), dans laquelle R désigne hydrogène ou un groupe organique quelconque, la solution électrolytique contenant, outre le formamide (I), au moins un sel conducteur.
