Title (EN) PROCESS FOR PREPARING AROMATIC URETHANE
(FR) PROCEDE DE PREPARATION D"URETHANE AROMATIQUE
Abstract: front page image
(EN)A process for preparing aromatic urethane by reacting an aromatic nitro compound, a hydroxy group-containing organic compound having at least one hydroxy group, and carbon monoxide at elevated temperatures under high pressure in the presence of a catalyst comprising a platinum group metal and/or a compound thereof, a Lewis acid, and a tertiary amine, which comprises allowing ferrous hydroxide and/or ferric hydroxide to coexist in the reaction system. This process so remarkably accelerates the reaction that it is completed in a short time, and the process enables the preparation of aromatic urethane in a high yield using a small amount of the platinum group metal catalyst.
(FR)Procede de preparation d"urethane aromatique consistant a faire reagir un compose nitro aromatique un compose organique contenant au moins un groupe hydroxy et du monoxyde de carbone a des temperatures elevees sous haute pression en presence d"un catalyseur comprenant un metal du groupe platine et/ou un compose d"un tel metal, un acide de Lewis, et une amine tertiaire, en permettant a un hydroxyde ferreux et/ou a un hydroxyde ferrique de coexister dans le systeme reactionnel. Ce procede ameliore remarquablement la cinetique de la reaction, et celle-ci s"effectue en un temps court, et permet la preparation d"urethane aromatique avec un rendement eleve en utilisant une petite quantite de catalyseur metallique du groupe platine.
