Abstract[German]
Ein Verfahren zur Gewinnung von Kohlenstoffdioxid aus Calciumcarbonat weist folgende Schritte auf: A) durch Zugabe von Essigsäure wird das Calciumcarbonat umgewandelt in Calciumacetat, wobei Wasser und Kohlenstoffdioxid gebildet werden; B) das Calciumacetat wird durch Erhitzen in Aceton und Calciumoxid umgewandelt, wobei Kohlenstoffdioxid gebildet wird; C) das Aceton wird in einem Reaktionsprozess unter Zugabe von Wasserstoffperoxid als eines der Edukte und in Anwesenheit eines Katalysators in Essigsäure als eines der Produkte umgewandelt.[English]
A method for obtaining carbon dioxide from calcium carbonate comprises the following steps: A) by addition of acetic acid, the calcium carbonate is converted into calcium acetate, wherein water and carbon dioxide are formed; B) the calcium acetate is converted by heating into acetone and calcium oxide, wherein carbon dioxide is formed; C) in a reaction process with addition of hydrogen peroxide as one of the reactants and in the presence of a catalyst, the acetone is converted into acetic acid as one of the products.[French]
L'invention concerne un procédé d'obtention de dioxyde de carbone à partir de carbonate de calcium comprenant les étapes suivantes : A) par ajout d'acide acétique, le carbonate de calcium est converti en acétate de calcium, de l'eau et du dioxyde de carbone étant formés ; B) l'acétate de calcium est converti par chauffage dans de l'acétone et de l'oxyde de calcium, le dioxyde de carbone étant formé ; C) lors d'un processus de réaction avec addition de peroxyde d'hydrogène en tant que l'un des réactifs et en présence d'un catalyseur, l'acétone est convertie en acide acétique en tant que l'un des produits.
