Paraan na Glyoxal Oxidation na Oxalic Acid
Say glyoxal et walaan na mabiskeg ya reducibility, kanian maples ya na-oxidize ya magmaliw ya oxalic acid diad panamegley na mabiskeg ya oxidizing nitric acid. Lapud saray bengatla a singa say suplay na hilaw a materyales, presyo, tan teknolohiya, sayan paraan et walaan na makapuy a kompetisyon ed merkado tan ag-in-industriyalisa.
Niarum ni, wala ni ray arum ya paraan na panaggawa na oxalic acid:
(1) Paraan na panagparaan na carbon dioxide: Say carbon dioxide et unonan nabawasan ed pegley
CO2
insan nauman ed arum ya organikon substansia. Say oxalic acid et naala diad pangi-irradiate ed nanduruman sistema na carbon dioxide panamegley na electrochemical iran paraan tan γ-ray, sinag na banwa, odino high-pressure mercury lamps.
(2) Paraan na panagtunaw na alkali ya uusaren iray materyales ya mayaman ed cellulose: Say laok na materyales ya mayaman ed cellulose (singa say basuran kiew, apa, tan arum nira) tan inorganic ya mabiskeg ya alkali et tinunaw ed 513-558 K pian makagawa na masulok ya 50% ya oxalate. Saray oxalate crystals et na-precipitate panamegley na crystallization, insan say sulfuric acid et usaren pian naala so asumpal ya oxalic acid. Sayan paraan et walaan na simplin proseso ed panagparaan na oxalic acid, balet say single-pass conversion rate et abeba (kulang ed 35%), atagey so konsumo na alkali, tan grabe so polusyon ed kaliberliber.
(3) Paraan na panaggawa na hilaw a materyales ed karbon: Iparaan manlapud nanduruman peats bilang hilaw a materyales. Singa bilang, say oxalic acid et napapawala manlapud peat na genera Sphagnum tan Polytrichum panamegley na nitric acid oxidation. Say reaksion et nagagawa ed 343 K ed loob na 8-9 oras, ya say ani et anggad 95%. No saray raw materials a singa say coal tar so usaren pian makagawa na oxalic acid, say ani et onsabi met ed 51%.
