Oxalic Acid Carbohydrate Ɔkwan a Wɔfa so Yɛ Oxidation
Saa kwan yi de starch ne asikre di dwuma sɛ nneɛma a wɔde yɛ nneɛma na ɛde nitric acid oxidize wɔ 73–80 °C ma ɛyɛ oxalic acid. Sɛ yɛfa starch sɛ nhwɛsoɔ a, ɔkwan a wɔfa so yɛ no te sɛ deɛ ɛdidi soɔ yi: Wɔde 85% mass fraction starch petepete nsuo a ɛwɔ mu a 10% oxalic acid anaa ɛna nsa a ɛwɔ nneɛma foforɔ a ɛwɔ ntam, de acid yɛ no hyew, na wɔsan de gu mu nnɔnhwereɛ 6 na ama wɔadi kan anya ntamgyinafoɔ glucose.
