Uburyo bwo Gukoresha Glyoxal Oxidation mu Bushinwa mu Gutunganya Acide Oxalic

Uburyo bwo gukuraho ogisijeni ya Glyoxal muri aside ya oxalic
Glyoxal ifite ubushobozi bwo kugabanya cyane, bityo ishobora guhindurwa oxidation vuba ikaba aside oxalic binyuze mu bikorwa bya aside nitrique ikomeye igabanya oxidation. Bitewe n'ibintu nk'ibicuruzwa fatizo bitangwa, igiciro, n'ikoranabuhanga, ubu buryo bufite ubushobozi buke bwo guhangana ku isoko kandi ntibwashyizwe mu nganda.
Byongeye kandi, hari ubundi buryo bwo gukora aside oxalic:
(1) Uburyo bwo gutegura dioxyde de carbone: Dioxyde de carbone ibanza kugabanuka ikagera ku rwego rwo hagati
CO2
hanyuma bigahinduka ibindi bintu by’umwimerere. Aside ya oxalike iboneka binyuze mu gukamura sisitemu zitandukanye za dioxyde de carbone hakoreshejwe uburyo bwa electrochemical na γ-rays, imirasire y’izuba, cyangwa amatara ya mercure afite umuvuduko mwinshi.
(2) Uburyo bwo gushongesha alkali hakoreshejwe ibikoresho bikungahaye kuri selulosi: Uruvange rw'ibikoresho bikungahaye kuri selulosi (nk'ibiti byanduye, ibihuru, nibindi) na alkali ikomeye idakora bishongeshwa kuri 513–558 K kugira ngo bikore oxalate irenga 50%. Uduce twa oxalate twinjizwamo na crystallization, hanyuma aside sulfurike igakoreshwa kugira ngo haboneke aside oxalic irangiye. Ubu buryo bufite uburyo bworoshye bwo gutegura aside oxalic, ariko igipimo cyo guhindura inshuro imwe ni gito (munsi ya 35%), ikoreshwa rya alkali ni rinini, kandi ihumana ry'ibidukikije ni rinini.
(3) Uburyo bwo gukora ibikoresho fatizo by'amakara: Bitegurwa mu mashanyarazi atandukanye nk'ibikoresho fatizo. Urugero, aside oxalike ikorwa mu mashanyarazi yo mu bwoko bwa Sphagnum na Polytrichum binyuze mu gutwika aside nitrike. Inzira ikorwa kuri 343 K mu gihe cy'amasaha 8-9, umusaruro ukagera kuri 95%. Iyo ibikoresho fatizo nka kaburimbo y'amakara bikoreshejwe mu gukora aside oxalike, umusaruro nawo ugera kuri 51%.

Shandong Pulisi Chemical Co., Ltd. – Impuguke mu bijyanye n'aside oxalic (aside ethanedioic)

Shandong Pulisi Chemical, ikigo gikomeye mu gukora imiti cyashinzwe mu 2006 i Zibo, mu Bushinwa, cyihariye mu gukora aside oxalic nziza cyane no gutanga umusaruro ku isi yose. Urutonde rwacu rw'ingenzi rw'ibicuruzwa bya aside oxalic rufite ubwoko bw'inganda (ubuziranenge bw'iminota 99.6) n'ubwoko bw'ibiribwa (ubuziranenge bw'iminota 99.8), ruboneka mu bwoko bwa dihydrate (H₂C₂O₄·2H₂O, CAS 6153-56-6) na anhydrous (H₂C₂O₄, CAS 144-62-7) kugira ngo ruhuze n'ibikenewe mu nganda bitandukanye.

Yakozwe hifashishijwe ikoranabuhanga rigezweho mu gukora no kugenzura neza ubuziranenge bihuye n’amahame ya ISO 9001:2015, aside oxalic yacu igaragaza umwanda uri hasi—sulfate ≤0.07%, ibyuma biremereye (Pb) ≤0.0005%, na feri (Fe) ≤0.0005%—ituma habaho ubwiza mu bikorwa bitandukanye kuva ku gusukura ibyuma no gusiga uruhu kugeza ku gutunganya amazi no gutunganya ibiribwa. Dufite ibyemezo byemewe birimo kubahiriza REACH no kwiyandikisha muri FAMI-QS, byemeza ko twubahiriza amahame mpuzamahanga y’umutekano n’ubuziranenge.

Dupakiye mu mifuka ya PP ifite uburemere bwa kg 25 (ishobora guhindurwa hamwe n'inyuguti) kugira ngo itumizwe mu nganda nyinshi, aside oxalic yacu iraboneka kugira ngo igerweho na FOB iturutse ku byambu bya Qingdao, Tianjin, cyangwa Shanghai. Dufite ubushobozi bwo gukora toni 3.000 buri kwezi hamwe n'itsinda ryihariye ry'ubushakashatsi n'iterambere, dutanga ibisubizo byihariye: gutumiza mu byiciro bito, gupakira mu buryo bwihariye, ndetse n'ubufasha mu bya tekiniki ku mishinga yihariye y'abakiriya. Nk'umucuruzi wizewe mu bihugu birenga 30, dushyira imbere ibikoresho ku gihe no gutumanaho mu buryo busobanutse, bigatuma tuba amahitamo meza yo kugura aside oxalic ku isi.
