【発明の名称】ペンテン酸類のヒドロカルボキシル化によるアジピン酸の製造法
Document Type and Number:
Japanese Patent JPH07112999
Kind Code:
B2
Abstract:
Process for the preparation of adipic acid by hydrocarboxylation of pentenic acids. …The invention relates more particularly to a process for the preparation of adipic acid by a reaction of water and carbon monoxide with at least one pentenic acid in the presence of a catalyst based on rhodium and of at least one iodine-containing promoter, at a temperature of between 100 and 240 DEG C at a pressure above atmospheric pressure, characterised in that … … a) the reaction is applied in the group consisting of saturated, aliphatic or cycloaliphatic hydrocarbons, aromatic hydrocarbons and their chloro derivatives and in that … b) the partial pressure of carbon monoxide, measured at 25 DEG C, is lower than or equal to 12 bar. …
