Abstract:
1. A method for reacting oxygen-containing polymers to form hydrogen and alkali metal carbonates, comprising: bringing polymers comprising carbon, hydrogen and oxygen atoms with and without further atoms into intimate contact with a molten mixture of alkali metal hydroxide and alkali metal carbonate; carrying out the reaction while avoiding direct contact of the interior of the employed reactor above the molten mixture with the oxygen of the atmosphere; and separating off the resulting hydrogen and crystallizing out and separating off the resulting alkali metal carbonate; wherein at least a quantity of alkali metal hydroxide is made available, and a concentration of alkali metal hydroxide is maintained in the reaction mixture during the reaction, which are sufficient to start and maintain an exothermic reaction of alkali metal hydroxide together with the oxygen-containing polymers.
