Uburyo bwo guhindura aside ya oxalic
Uwo murongo wo guhindura ibara ry’umubiri (oxidation) usa cane n’uburyo bwo guhindura ibara ry’umubiri ry’imitsi. Igisubizo c’amazi c’ethylène glycol kirashushwa gushika ku bushuhe bwa 60 °C, hanyuma aside ivanze (30%–40% ya aside sulfurique ku buremere, 20%–25% ya aside nitrique ku buremere) n’aside ya vanadium pentoxide bigashirwamwo mu gutera imbere cane. Ivyo bihimba vy’umubiri bikora ku bushuhe bwa 50–70 °C no ku bushuhe bwa 1,3–4,0 kPa. Ico kintu kirakonjeshwa, kigahinduka ikibiriti, kigacungururwa kugira ngo kironke aside oxalic ifise ubusuku bwa 99,9% n’umwimbu urenga 90%. Ubwo buryo burashobora gukoreshwa mu bihe bitatu: umuvuduko wo mu kirere, umuvuduko ugabanutse, n’umuvuduko wongerekanye. Ifise uburyo bworoshe, itanga umusaruro mwinshi w’aside oxalique, uburyo bwiza bw’ibicuruzwa, kandi hafi y’ugusubirana kw’aside nitrique, ariko igiciro c’ibikoresho vya mbere ni kinini.

Ishirahamwe ry'imiti ry'i Shandong Pulisi, Ltd. Asidi y'amazi y'amazi – Igitigiri c'inganda 99,6%
Ishirahamwe ry’imiti ryitwa Shandong Pulisi Chemical Co., Ltd., ryizigiwe rikora imiti kandi rirungika hanze kuva mu 2006, ryitaho cane guhingura imiti y’ubusuku bwinshi (H2C2O4·2H2O, CAS 6153-56-6, EINECS6-542. Asidi yacu y’ubuhinga bwa oxalic irafise ubusuku bukeyi bwa 99,6%, igaragara nk’ifu y’ikibiriti yera ifise ubuhumane buke (sulfate ≤0,1%, ivyuma biremerera ≤0,002%, icuma ≤0,003%). Ikoreshwa cane mu gucapura impuzu no gutera ibara, gutunganya urukoba, gusukura ivyuma, gusukura amabuye y’agaciro, gusukura amazi, gukura ubutaka budasanzwe, no gukora imiti yo hagati.
Turabungabunga ibikoresho vyinshi biri mu bubiko bwacu bwo mu gisagara ca Shandong, bikaba bituma dushobora guca twohereza amategeko menshi. Uburyo bwo gupfunyika bushobora guhinduka (imifuko y’ibiro 25, ibiro 50, ibiro 1000) be n’ugutuma ibintu kw’isi yose biva ku vyambu vya Qingdao, Tianjin, canke Shanghai bituma bishika ku gihe kw’isi yose. Turatanga ubufasha bushitse mu vy’ubuhinga, ivyangombwa vya COA/MSDS, n’ibiciro bihuye kugira ngo dushobore gushitsa ivyipfuzo bitandukanye vy’inganda.
Twandikire uno musi kugira ngo ubone igiciro gisanzwe kandi ukingire uruhererekane rwawe rwo gutanga aside ya oxalic.
