| titleOfInvention | Process for the treatment of alkaline solutions containing aromatic polymers |
| abstract | A method that allows for reliable and clean separationnaromatic polymers, particularly those found in wastenfrom the production of pulp, namely in pure form by their precipitationnafter acidification from alkaline solutions. To achieve goodnseparability, especially filtration, is the need for precipitationnpolymers reduce the pH value at a relatively low temperature, vntypically between 15 and 60 ° C, and subsequentnre-heating the respective dispersion until it passes intonfilterable forms, typically between 50 and 90n° C. For example, by filtration, the thus separated product may be washednand dried at high temperatures up to 110 ° C without blackening. |
