Ụzọ Oxidation nke Carbohydrate Oxalic Acid
Usoro a na-eji starch na shuga dị ka ihe eji emepụta ihe ma na-eme ka ha dị ọcha na nitric acid na 73–80 °C iji mepụta oxalic acid. Dịka ọmụmaatụ, usoro a bụ ndị a: A na-agbasa starch nke 85% n'ime mmiri mmiri nwere 10% oxalic acid ma ọ bụ ihe ọṅụṅụ nne nke ngwaahịa ndị ọzọ dị n'etiti, kpoo ya ọkụ na acid, ma tinye ya n'ime mmiri ruo awa isii iji nweta glucose ngwaahịa dị n'etiti. Mgbe ahụ, a na-agbakwunye nitric acid na ihe na-akpali iron-vanadium na 63 °C maka hydrolysis ọzọ, a na-enwetakwa oxalic acid site na nchacha mgbe mmeghachi omume gasịrị.
