| titleOfInvention | Process for the preparation of metalformate-formic acid mixtures |
| abstract | a) Umsetzung von mindestens einem Metallhydroxid mit Kohlenmonoxid oderneinem Kohlenmonoxid-haltigen Gas in Gegenwart eines Katalysators in einernwasserhaltigen Lösung zu dem oder den entsprechenden Metallformiat(en); b) destillative Abtrennung des Wassers und des Katalysators; c) Zumischen von Ameisensäure; d) gegebenenfalls Einstellen der Temperatur der nach den Schritten a) bis c)nerhaltenen Metallformiat-Ameisensäure-Mischung auf Lagertemperatur; nwobei in Schritt a) als Metallhydroxide die Hydroxide von Alkalimetallen und/oder Erdalkalimetallenneingesetzt werden und Schritt c) auch zeitlich vor Schritt b) durchgeführtnwerden kann.The invention relates to a process for the preparation of metal formate-formic acid mixtures comprising the following steps: a) reaction of at least one metal hydroxide with carbon monoxide or a carbon monoxide-containing gas in the presence of a catalyst in a water-containing solution to the corresponding metal formate (s); b) separation of the water and the catalyst by distillation; c) admixing formic acid; d) optionally adjusting the temperature of the metal formate-formic acid mixture obtained after steps a) to c) to storage temperature; wherein in step a) the hydroxides of alkali metals and / or alkaline earth metals are used as metal hydroxides and step c) can also be carried out before step b).n n n At least one catalyst from the group consisting of alcohol and formic acid ester is used as the catalyst. Preferred catalysts are linear C 1 -C 4 -, branched C 3 -C 4 alkanols and their formic acid esters. Preferred metal hydroxides are the hydroxides of sodium, potassium and / or calcium. The concentration of the formic acid used in step c) is generally 80 to 99.99% by weight in water, and the storage temperature in step d) is a temperature of 0 to 40 ° C. |
