Uburyo bwo guhindura aside ya oxalic
Glyoxal irafise ubushobozi bwo kugabanya cane, rero irashobora guhinduka vuba cane ikaba aside oxalique mu gihe ikoreshwa n’aside nitrique ikomeye ihindura aside. Kubera ibintu nk’ugutanga ibikoresho vya mbere, igiciro, n’ubuhinga, ubu buryo burafise ubushobozi buke bwo guhangana n’isoko kandi ntibwashizwe mu nganda.
Ikindi, hariho ubundi buryo bwo gukora aside oxalique:
(1) Uburyo bwo gutegura umwuka w’ikirere: Umwuka w’ikirere ubanza kugabanywa ukaja hagati .
CO2
hanyuma bikahinduka ibindi bintu bifise ubuzima. Asidi ya oxalique ironswa mu gutera imishwarara mu bikoresho bitandukanye vy’umuyagankuba bikoresheje uburyo bw’ubuhinga bw’amashanyarazi be n’imishwarara ya γ, umuco w’izuba canke amatara y’umuyagankuba afise umuyagankuba mwinshi.
(2) Uburyo bwo gufukura alkali hakoreshejwe ibikoresho birimwo cellulose: Ivangura ry’ibikoresho birimwo cellulose (nk’ibiti vy’imyanda, umukungugu, n’ibindi) n’ivyuma bikomeye bitagira ubuzima birafungwa hamwe ku 513–558 K kugira ngo bivemwo oxalate irenga 50%. Ivyo bihimba vy’umubiri bita oxalate bica bihinduka ibisigazwa, hanyuma hakoreshwa aside sulfurique kugira ngo haboneke aside oxalique irangije. Ubwo buryo burafise uburyo bworoshe bwo gutegura aside oxalique, ariko igipimo co guhindura aside imwe gusa ni gito (kiri munsi ya 35%), ugukoresha alkali ni kwinshi, kandi uguhumana kw’ibidukikije ni gukomeye cane.
(3) Uburyo bwo gukora ibikoresho vya mbere vy’amakara: Bitegurwa bivuye mu bihimba vy’umubiri bitandukanye nk’ibikoresho vya mbere. Nk’akarorero, aside oxalique iva mu mfuruka z’ivyatsi vy’ubwoko bwa Sphagnum na Polytrichum biciye ku guhindura aside nitrique. Ivyo bihimba bikoreshwa ku 343 K mu kiringo c’amasaha 8–9, bikaba bitanga umwimbu ushika kuri 95%. Iyo hakoreshejwe ibikoresho vya mbere nk’ibiti vy’amakara kugira ngo haboneke aside oxalique, umusaruro na wo nyene urashika kuri 51%.

Ishirahamwe ry'imiti ry'i Shandong Pulisi, Ltd. – Umuhinga mu vy'aside ya Oxalic (Aside ya Ethanedioic)

Shandong Pulisi Chemical, ni ishirahamwe rikomeye ry’ubuhinga bw’imiti ryashinzwe mu 2006 i Zibo mu Bushinwa, ryitaho cane guhingura aside oxalique y’ubusuku bwinshi no kuyitanga kw’isi yose. Umurongo wacu w’ibintu vy’agaciro vy’aside oxalique ufise urugero rw’inganda (99,6% ubusuku bw’iminota) n’urugero rw’ibifungurwa (99,8% ubusuku bw’iminota), uboneka mu mice yompi y’amazi (H2C2O4·2H2O, CAS 6153-56-6) n’amazi atagira amazi (H22-6-7C) amafomu kugira ngo ashobore gushitsa ivyo inganda zikeneye zitandukanye.

Igizwe n’ubuhinga buteye imbere bwo gukora ibintu be n’ukugenzura neza uburyo bihuye n’ingingo mfatirwako za ISO 9001:2015, aside yacu yerekana ubuhumane buke—sulfate ≤0.07%, ivyuma biremerera (Pb) ≤0.0005%, n’ubushobozi bwo gukoresha ivyuma (Fe) ≤0005. kuva ku gusukura ivyuma no gukora urukoba gushika ku gusukura amazi no gutunganya ibifungurwa. Turafise ivyemezo vyemewe harimwo n’ukubahiriza REACH n’ukwiyandikisha kwa FAMI-QS, vyemeza ko twubahiriza amategeko mpuzamakungu yerekeye umutekano n’uburyo.

Ishizwe mu masaho y’ibilo 25 (ishobora guhindurwa n’icapa ry’ikimenyetso) ku bijanye n’amategeko menshi y’inganda, aside yacu ya oxalic iraboneka kugira ngo ishikirizwe FOB ivuye ku vyambu vya Qingdao, Tianjin, canke Shanghai. Kubera ko dufise ubushobozi bwo gukora amatoni 3.000 ku kwezi be n’umugwi wihariye w’ubushakashatsi n’iterambere, turatanga inyishu zihuye n’ivyo dukeneye: amategeko y’ibice bitobito, gupfunyika ibintu bihuye n’ivyo umuntu akeneye, n’ugufasha mu vy’ubuhinga imigambi yihariye y’abaguzi. Nk’umucuruzi yizigirwa mu bihugu birenga 30, dushira imbere ivy’ugutanga ibikoresho ku gihe no guhanahana amakuru mu buryo buboneye, ivyo bikaba bituma tuba abahisemwo mu bijanye n’ugugura aside oxalique kw’isi yose.
