Indlela yokwenza i-Glyoxal Oxidation ye-Oxalic Acid
I-glyoxal inokunciphisa okunamandla, njeke ingatjhuguluka msinyana ibe yi-oxalic acid ngaphasi kwesenzo se-nitric acid enamandla. Ngebanga lezinto ezifana nokunikelwa kwezinto ezisetjenziswako, intengo, kanye nethekhnoloji, indlela le ayikho ukuncintisana okumbi emakethe begodu ayikafakwa emabubulweni.
Ukungezelela, kunezinye iindlela zokwenziwa ze-oxalic acid:
(1) Indlela yokulungiselela i-carbon dioxide: I-carbon dioxide ithoma yehliswa ibe phakathi
CO2
bese itjhugululwa ibe ngezinye izinto eziphilako. I-oxalic acid itholakala ngokufaka imisebe ehlukileko ye-carbon dioxide ngeendlela ze-electrochemical kanye nama-γ-ray, ukukhanya kwelanga, nofana amalambu we-mercury anegandelelo eliphezulu.
(2) Indlela yokuncibilikisa i-alkali ngokusebenzisa izinto ezine-cellulose: Umxube wezinto ezine-cellulose (njengeenkuni ezilahliweko, i-chaff, njll.) kanye ne-alkali eqinileko engaphiliko iyancibilikiswa ku-513-558 K ukukhiqiza i-oxalate engaphezu kwama-50%. Amakristalu we-oxalate athonywa ngokukhiqiza, bese kuthi i-sulphuric acid isetjenziselwe ukuthola i-oxalic acid eqediweko. Indlela le inendlela elula yokulungiselela i-oxalic acid, kodwana izinga lokutjhuguluka kwe-single-pass liphasi (ngaphasi kwama-35%), ukusetjenziswa kwe-alkali kuphezulu, begodu ukusilaphazeka kwebhoduluko kukhulu.
(3) Indlela yokukhiqiza amalahle: Ilungiselelwe ngama-peats ahlukahlukeneko njengezinto ezisetjenziswako. Ukwenza isibonelo, i-oxalic acid yenziwa nge-peat ye-genera ye-Sphagnum ne-Polytrichum ngokusebenzisa i-nitric acid oxidation. Ukusabela kwenziwa ku-343 K ama-awa ayi-8-9, ngokukhiqiza okufika ku-95%. Lokha izinto ezisetjenziswako ezifana ne-coal tar nazisetjenziselwa ukukhiqiza i-oxalic acid, isivuno naso sifikelela ku-51%.
