Omuringo gw'okuhindura asidi ya oksaaliki
Omuringo ogu gw’okuhindura ebiriisa nigushushana munonga n’omuringo gw’okuhindura ebiriisa omu sitaaki. Omubazi gw’amaizi ogwa ethylene glycol niguteebwa omu muriro kuhika ahari 60 °C, kandi asidi etaburiirwe (30%–40% asidi y’ekibiriiti omu bwingi, 20%–25% asidi ya nitric omu bwingi) na vanadium pentoxide nibiyongyerwamu ahansi y’okugiteera n’amaani. Okuhindura ebiriisa nikukorwa aha 50–70 °C na 1.3–4.0 kPa. Ekintu eki nikifukiirizibwa, kihindurwa ekicupuri, kandi kishwijumwa kutunga oxalic acid erimu obuyonjo bwa 99.9% kandi erikureeta ebiriisa ebirikukira ahari 90%. Omuringo ogu nigubaasa kukorwa omu mbeera ishatu z‘omuringo: okukyendeeza aha nkora y‘omuyaga, okukyendeeza aha nkora, n‘okwongyera aha nkora. Nikigira omuringo gworobi, nikireeta oxalic acid nyingi, omutindo murungi gw’ebintu, kandi haihi n’okugarukaho kwa nitric acid, kwonka omuhendo gw’ebintu ebikuru nigukira.

Shandong Pulisi Chemical Co., Ltd. Oxalic Asid Dihydrate – Omutindo gw’amakorero 99.6% Obushemeire
Shandong Pulisi Chemical Co., Ltd., omukozi w’emibazi orikwesigwa kandi orikugitwara aheeru y’ihanga kuruga 2006, aine obukugu omu kuhanga emibazi y’obuyonjo bw’ahaiguru (H2C2O4·2H2O, CAS 6153-56-6, EINECS-50 control30. Oxalic acid yaitu ey’omutindo gw’amakorero neeyehimbisa ahabw’obushemeire obukye bwa 99.6%, erikureebeka nk’esacu y’ekibiriiti erikwera erimu obutashemeire bukye (sulfate ≤0.1%, ebyoma ebiremeire ≤0.002%, ekyoma ≤0.003%). Nikikozesibwa munonga omu kuhandiika emyenda & okugiteera erangi, okukora aha ruhu, okuboneza aha mutwe gw’ebyoma, okushemeza amabaare g’omuhendo, okushemeza amaizi, okushohoza eitaka eritarikukira kureebwa, n’okukora emibazi y’omugati.
Nituguma nitubiika ebintu bingi omu ibiiko ryaitu erya Shandong, ekirikubaasisa kwohereza ahonaaho ahabw’okugura ebintu bingi. Ebintu ebirikuhindukahinduka (enshaho za kiro 25, kiro 50, kiro 1000) n’okubitwara omu nsi yoona kuruga aha myaaro ya Qingdao, Tianjin, nari Shanghai nibihamya ngu byahikwa omu bwire omu nsi yoona. Nituha obushagiki bwona obw’eby’obuheereza, ebihandiiko bya COA/MSDS, n’emihendo y’okuhakanisa kuhikiiriza ebyetaago by’amakorero ebitari bimwe na bimwe.
Tuhikireho erizooba kutunga esente ezi orikwenda kandi otungye n'okurinda oxalic acid yaawe.
