Omuringo gw’okuhindura asidi ya Oxalic

Omuringo gw’okuhindura asidi ya Oxalic
Glyoxal eine okukyendeeza kw’amaani, n’ahabw’ekyo neebaasa kurahuka kuhinduka oxalic acid ahansi y’ebikorwa bya nitric acid y’amaani erikuhindura okisidi. Ahabw‘enshonga nk‘okutunga ebintu ebitari bimwe na bimwe, omuhendo, na tekinologiya, omuringo ogu gwine okuhakanisa kubi omu katare kandi tigukakozesiibwe omu makorero.
Okwongyera ahari ekyo, hariho emiringo endiijo ey’okukora oxalic acid:
(1) Omuringo gw’okutebeekanisa omuyaga gwa kaboni: Omwika gwa kaboni nigubanza gwakyendeezibwa guhika ahagati .
CO2
kandi bwanyima bikahindurwa ebindi bintu ebiine amagara. Oxalic acid neetunga omu kujwisa omushana omu nkora zitari zimwe na zimwe eza carbon dioxide n’emiringo y’amashanyarazi n’omushana gwa γ-rays, omushana gw’eizooba, nari etabaaza z’amaani maingi eza mercury.
(2) Omuringo gw’okusheenya alkali orikukoresa ebintu ebirimu cellulose: Okutabura ebintu ebirimu cellulose (nk’ebiti ebikozirwe omu itaka, ebishaka, n’ebindi) na alkali ey’amaani etari y’obuhangwa nibishuuma hamwe aha 513–558 K kureetaho oxalate erikurenga 50%. Ebicupuri bya oxalate nibisheesheka ahabw’okuhinduka ebicupuri, reero sulfuric acid neekoresibwa kutunga oxalic acid ehweire. Omuringo ogu gwine omuringo gworobi gw’okutebeekanisa oxalic acid, kwonka omubaro gw’okuhindura omurundi gumwe nigukye (ahansi ya 35%), okukoresa alkali nikwingi, kandi okushiisha eby’obuhangwa nikwingi munonga.
(3) Omuringo gw’okukora ebintu ebikuru eby’amakara: Nibitebeekanisibwa kuruga omu bishaka bitari bimwe na bimwe nk’ebintu ebikuru. Nk’eky’okureeberaho, oxalic acid neeruga omu itaka ry’ebishaka eby’omu kika kya Sphagnum na Polytrichum kurabira omu kuhindura asidi ya nitric. Okugarukamu nikukorwa aha 343 K kumara eshaaha 8–9, n’okutunga ebiriisa ebirikuhika ahari 95%. Ebintu ebitari birungi nk’ekyoma ky’amakara ku birikukoresibwa kureetaho oxalic acid, n’ebirikurugamu nabyo nibihika ahari 51%.

Omuhangu omu by’emibazi ya Shandong Pulisi

Shandong Pulisi Chemical, kampuni erikwebembera omukukora emibazi eyatandikireho omu mwaka gwa 2006 omuri Zibo, China, neekora gye omukukora oxalic acid ey’obuyonjo bw’ahaiguru n’okugireeta omunsi yoona. Omuringo gwaitu gw’ebintu bya oxalic acid ogw’omutaano gwine omutindo gw’amakorero (99.6% obushemeire bw’edakiika) n’omutindo gw’eby’okurya (99.8% obushemeire bw’edakiika) ebirikutaana, ebirikushangwa omu miringo ebiri ey’amaizi (H2C2O4·2H2O, CAS 6153-56-6-6222-642) foomu z‘okuhikiiriza ebyetaago by‘amakorero ebitari bimwe na bimwe.

Ekozirwe n’eby’obuhangwa eby’omurembe n’okurinda omutindo gw’ebintu ebigumire ebirikuhikaana n’omutindo gwa ISO 9001:2015, oxalic acid yaitu neeyoreka obukooko bukye—sulfate ≤0.07%, ebyoma ebiremeire (Pb) ≤0.0005%, n’okukoresa eby’ekyoma (Fe) ≤0005. okuruga aha kuboneza ebyoma n’okushemeza oruhu kuhika aha kuboneza amaizi n’okukora eby’okurya. Twine ebihandiiko by‘obushoboorozi ebirimu okukuratira REACH n‘okwehandikisa kwa FAMI-QS, ebirikuhamya okukuratira kwaitu emitindo y‘ensi yoona ey‘obukuumi n‘omutindo.

25kg omu nshaho za PP ezirukire (ezirikubaasa kuhindurwa n’okuhandiika akamanyiso) ahabw’okuragiira kw’amakorero omu bwingi, oxalic acid yaitu neebaasa kuheebwayo FOB kuruga aha myaaro ya Qingdao, Tianjin, nari Shanghai. N’obushoboorozi bw’okukora tani 3,000 buri kwezi n’ekibiina ky’okucondooza n’okutunguuka ekihaireyo, nituha eby’okugarukamu ebihikire: okuragiira omu bicweka bikye, okubiteeka omu bipapura nk’oku orikwenda, n’obuhwezi bw’eby’obuhangwa ahabwa purojekiti z’abaguzi. Nk’omuhi w’ebintu orikwesigwa omu mahanga garikurenga 30, nitwebembeza okutwara ebintu omu bwire n’okugaaniira omu bwesigwa, ekirikutuhindura okutooranwa okurikukirayo omu kugura oxalic acid omu nsi yoona.
