Verfahren zur Oxydation von Polyacroleinen

摘要

Polymers of a -unsaturated aldehydes are oxidized in an aqueous alkaline medium containing alkali-metal ions, using as oxidizing agent a mixture of cupric oxide or cupric hydroxide and a noble metal or noble metal oxide or noble metal hydroxide, to produce the appropriate alkali-metal salt of the polycarboxylic acid. The oxidizing agent can be regenerated in situ.
