Fremgangsmåde til fremstilling af metaltalformiat-myresyreblandinger

摘要

A process for the production of metal formate-formic acid mixtures comprises reaction of a metal hydroxide with carbon monoxide or a carbon monoxide containing gas in the presence of a catalyst in an aqueous solution to form the corresponding metal formate; separation of the water and catalyst by distillation; and addition of formic acid. A process for the production of metal formate-formic acid mixtures (I) comprises: (A) reaction of a metal hydroxide with carbon monoxide or a CO containing gas in the presence of a catalyst in an aqueous solution to form the corresponding metal formate; (B) separation of the water and catalyst by distillation; (C) addition of formic acid; and (D) optionally adjusting the temperature of the mixture (I) following steps (A)-(C) to the storage temperature whereby the metal hydroxide is an alkali metal and/or alkaline earth metal and step (C) is optionally carried out before step (B).
