Uburyo bwo gupima aside ya oxalic hakoreshejwe ethylene glycol nitrique
Iyi gahunda yo gukaraba isa cyane n'uburyo bwo gukaraba starch. Umuti wa ethylene glycol w'amazi ushyushywa kugeza kuri 60 °C, hanyuma aside ivanze (30%–40% aside sulfurike ku bunini, 20%–25% aside nitrike ku bunini) na vanadium pentoxide byongerwamo mu buryo bukomeye. Gukaraba bikorwa kuri 50–70 °C na 1.3–4.0 kPa. Umuti urakonjeshwa, ugashyirwamo kristali, hanyuma ukayungururwa kugira ngo haboneke aside oxalic ifite ubuziranenge bwa 99.9% n'umusaruro urenga 90%. Ubu buryo bushobora gukorwa mu bihe bitatu: umuvuduko w'ikirere, umuvuduko ugabanuka, n'umuvuduko wiyongera. Ufite inzira yoroshye, umuvuduko mwinshi wa aside oxalic, ubwiza bwiza bw'umusaruro, no kugarura aside nitrike hafi ya yose, ariko igiciro cy'ibikoresho fatizo kiri hejuru.

Shandong Pulisi Chemical Co., Ltd. Oxalic Acid Dihydrate – Ingano y'inganda 99.6% Ubuziranenge
Shandong Pulisi Chemical Co., Ltd., ikigo cyizewe mu gukora imiti no kohereza mu mahanga kuva mu 2006, cyihariye mu gukora aside oxalic dihydrate (H₂C₂O₄·2H₂O, CAS 6153-56-6, EINECS 205-634-3) gifite igenzura rikomeye ry’ubuziranenge. Aside oxalic yacu yo mu rwego rw’inganda ifite ubuziranenge bungana na 99.6%, igaragara nk'ifu y'umweru ifite umwanda muto (sulfate ≤0.1%, ibyuma biremereye ≤0.002%, icyuma ≤0.003%). Ikoreshwa cyane mu gucapa no gusiga amarangi imyenda, gutunganya uruhu, gusukura ibyuma, gusiga amarangi ya marble, gutunganya amazi, gukuramo ivumbi ridasanzwe, no gukora imiti hagati.
Dufite ububiko bwinshi buri mu bubiko mu bubiko bwacu bwa Shandong, bigatuma twohereza ibicuruzwa byihuse ku buryo bunini. Uburyo bworoshye bwo gupakira (imifuka 25kg, 50kg, 1000kg) hamwe n'uburyo bwo kohereza ibicuruzwa ku isi yose bivuye ku byambu bya Qingdao, Tianjin, cyangwa Shanghai butuma bitangwa ku gihe ku isi yose. Dutanga ubufasha bwuzuye mu bya tekiniki, inyandiko za COA/MSDS, hamwe n'ibiciro bishimishije kugira ngo duhuze n'ibikenewe mu nganda zitandukanye.
Twandikire uyu munsi kugira ngo ubone ibiciro byihariye kandi ushyireho uburyo bwo gucunga umuyoboro wawe w’amazi aside oxalic.
