Uburyo bwa Sodium Formate bwo gukoresha aside oxalic
Uburyo bwo gukora aside oxalic hakoreshejwe uburyo bwa sodium formate bugabanyijemo uburyo bwa lead na calcium method. Monoxide ya karuboni inyuzwa mu gisubizo cya sodium hydroxide kugira ngo haboneke sodium formate, hanyuma igakurwamo hydrogene kugira ngo habeho sodium oxalate. Iyi ya nyuma ihura na sulfate ya lead (uburyo bwa lead) cyangwa calcium hydroxide (uburyo bwa calcium) kugira ngo habeho lead oxalate precipitate cyangwa calcium oxalate precipitate, hanyuma ishyirwamo aside sulfuric kugira ngo habeho oxalic acid.
Uburyo bwo gukora aside ya oxalic: Nyuma yo gukaraba, gukaraba alkali, no gukuraho ivumbi, monoxide ya karuboni ishyirwa kuri 2 MPa na compressor, ishyushye kugeza kuri 150 °C hamwe na 160 g/L sodium hydroxide, hanyuma ikoherezwa muri reactor kugira ngo ikore umuti wa sodium formate uvanze. Umuti ushyirwa kuri 600 g/L, woherezwa mu isafuriya idafite hydrogenation kugira ngo ishyushye kandi ihuzwe mu kintu gikomeye, hanyuma ishyushye kandi ishonge, hanyuma ikavanwaho hydrogenation kuri 400 °C. Sodium oxalate idafite hydrogenation itegurwa mu buryo bwo gufunga, hanyuma sulfate ya lead ikongerwamo mu gihe pH igumana agaciro ka 3–4. Imyanda ishongeshwa ikurwaho mu gukaraba, hanyuma aside sulfuric irenze yongerwaho kugira ngo ihindurwe kugira ngo haboneke umuti wa aside ya oxalic. Barium carbonate na 1% polyacrylamide byongerwaho kugira ngo bifatanye kandi bivanweho kugira ngo bikureho imyanda. Umuti urakonjeshwa, ukarangizwa, uyungururwa hakoreshejwe centrifugation, hanyuma wumishwa kugira ngo ubone umusaruro urangiye.
Uburyo bwa kalisiyumu bwo gukora aside oxalic: Ifu ya sodium oxalate yateguwe hamwe na calcium hydroxide suspension bipimwa hanyuma bikoherezwa muri reactor ya kalisiyumu kugira ngo habeho reaction ya kalisiyumu irimo kuvanga. Amazi ya kalisiyumu yabonetse arayungururwa hanyuma akagezwa. Filtrate sodium hydroxide irahuzwa kandi igakoreshwa mu gukora formate ya sodium, naho calcium oxalate ya filter ikoreshwa mu gukora reaction ya aside. Ifu ya filter itegurwa mu ifu ya kalisiyumu oxalate, igashyirwamo aside mu isafuriya irimo aside sulfurike na aside oxalic ya vinyl, hanyuma ikayungururwa. Ifu ya filter (gypsum) irasukurwa, hanyuma amazi yo kumesa agakoreshwa mu gutegura ifu ya kalisiyumu oxalate. Ifu ya filter (solution ya aside oxalic) irashyirwa mu mazi kugira ngo ikuremo uduce duto twa kalisiyumu sulfate, ikonjeshwa, ikarangizwa, hanyuma ikarangizwa kugira ngo itandukane aside oxalic, ikongera guhindurwa, igatandukanywa, kandi yumishwe kugira ngo haboneke umusaruro wujuje ibisabwa, hanyuma ifu ya filter ikongera gukoreshwa.
Uburyo bwa sodium formate lead bufite inzira ikuze, ubwiza bw'umusaruro buhamye, kandi ukwezi guto gukora, umusaruro uri hagati ya 80%–90% n'ubuziranenge bwa aside oxalic ya 99.5%. Ariko, hari umwanda wa lisansi mu gikorwa cyo gukora, kandi sodium sulfate iboneka muri reaction ntishobora kugaruka muri icyo gikorwa, bityo ingano nini ya aside sulfurike na soda caustic ikoreshwa mu gukora. Uburyo bwa kalisiyumu bwo gukora aside oxalic bushobora gukuraho umwanda w'umunyu wa lisansi na sodium sulfate mu mazi yo munsi y'ubutaka, kandi gusimbuza soda caustic na lime bishobora kugabanya cyane ikiguzi cyo gukora. CaSO4 y'umusaruro iboneka muri reaction ishobora gutunganywa mu bikoresho by'ubwubatsi nta mwanda. Muri icyo gihe, inzoga NaOH iboneka muri reaction ikoreshwa mu gukora reaction na CO mu gutegura sodium formate, bityo ikagabanya ingano y'ibikoresho fatizo.

Aside Oxalic Chemical ya Shandong Pulisi: Ibyiza by'ingenzi
Aside oxalic ya Shandong Pulisi Chemical (≥99.6% ubuziranenge, CAS 144-62-7) iratandukanye cyane n'imyanda iri hasi cyane (sulfate ≤0.1%, ibyuma biremereye ≤0.002%, icyuma ≤0.003%) na ISO 9001, BV, REACH, FAMI-QS, bishimangira ko amasoko mpuzamahanga yujuje ibisabwa. Dushyigikiwe n'ubuhanga bw'imyaka irenga 18 mu bya shimi, dutanga ibiciro bitaziguye mu ruganda, ibikoresho byuzuye hamwe n'ububiko hirya no hino mu byambu bya Qingdao, Tianjin, Shanghai, hamwe n'ibipfunyika byihariye (25kg/50kg) byo kohereza ibicuruzwa mu mahanga mu buryo butaziguye Shandong Pulisi Chemical Group. Aside oxalic yacu irahebuje mu imvura y'icyuma gisanzwe, gukuraho ingese mu byuma, gusiga irangi mu myenda, no gusiga marble, itanga imikorere ihamye n'ibisubizo birambye kandi bishobora kwangirika ku bakiriya b'inganda ku isi yose.
