Glyoxal Oxidation Mɔnu si Wotsɔ Wɔa Oxalic Acid
Glyoxal ƒe ɖiɖi sesẽ le esi, eyata woate ŋu awɔe kabakaba wòazu oxalic acid le nitric acid sesẽ si naa oxidation ƒe dɔwɔwɔ te. Le nusiwo nye nu xoxowo ƒe agbɔsɔsɔ, asixɔxɔ, kple mɔ̃ɖaŋununya ta la, asitsatsa ƒe hoʋiʋli mede mɔnu sia nu o eye womewɔe le dɔwɔƒewo o.
Tsɔ kpe ɖe eŋu la, mɔnu bubu siwo wotsɔ wɔa oxalic acid hã li:
