Uburyo bwo gukora aside ya oxalic
Uguhingura aside oxalique hakoreshejwe uburyo bwa sodium formate bigabanywamwo uburyo bw’amabuye y’agaciro n’uburyo bwa calcium. Monoxide de carbone inywanywa n’umunyu w’ivyuma vy’ivyuma kugira ngo haboneke formate y’ivyuma, hanyuma igaca ihinduka ivyuma vy’ivyuma kugira ngo ibone oxalate y’ivyuma. Ivyo vya nyuma bikorana n’ivyuma vy’amabuye y’agaciro (uburyo bw’amabuye y’agaciro) canke n’ivyuma vy’amabuye y’agaciro (uburyo bw’ivyuma) kugira ngo bivemwo ivyuma vy’amabuye y’agaciro canke ivyuma vy’amabuye y’agaciro, ivyo bikaba bica bihindurwa aside n’ivyuma vy’amabuye y’agaciro kugira ngo haboneke aside y’amabuye y’agaciro.
Uburyo bwo gukora aside y’amabuye y’agaciro: Inyuma yo gukaraba, gukaraba n’amazi y’amazi, no gukuraho inkungugu, monoxide ya carbone irafatwa ku 2 MPa n’igikoresho co gufata, igashushwa gushika ku 150 °C n’amazi y’amazi 160 g/L ya sodium hydroxide, hanyuma igarungikwa mu gikoresho co gukora umunyu w’amazi y’amazi y’amazi. Ico gisubizo gica gishirwa hamwe gushika nko kuri 600 g/L, kigarungikwa mu gitereko co gukuraho amazi kugira ngo gishushe kibe ikintu gikomeye, hanyuma kigashushwa kigafungwa, hanyuma kigakurwamwo amazi ku bushuhe bwa 400 °C. Ivyo bihimba vy’umubiri bita sodium oxalate bitegurwa mu gitereko, hanyuma lead sulfate yongerwako iyo ivyuka mu gihe pH iguma kuri 3–4. Ibintu bihumanye bishobora gusenyuka birakurwamwo biciye mu gukaraba, hanyuma bagashiramwo aside sulfurique irenze urugero kugira ngo ihinduke aside kugira ngo haboneke umuti w’aside oxalique. Barium carbonate na polyacrylamide 1% vyongerwako kugira ngo bibe bikomeye kandi bibe ibisigazwa kugira ngo bikureho ubuhumane. Ico gisubizo kirakonjeshwa, kigacika nk’ikibiriti, kigacungururwa hakoreshejwe ubuhinga bwa centrifugation, hanyuma kikayumwa kugira ngo haboneke igisubizo giheza.
Uburyo bwo gukora aside ya oxalic: Ivyo bihimba vy’umubiri biteguwe n’ivyo bihimba vy’umubiri biteguwe biragereranywa hanyuma bikarungikwa mu gikoresho co gukora calcium kugira ngo bikore igikorwa co gukora calcium mu gihe bivugururwa. Ivyo bihimba vy’umubiri biva muri calcium biracungururwa hanyuma bikayozwa. Ivyo bihimba vy’umubiri vyitwa sodium hydroxide birakoranywa cane kandi bikakoreshwa mu gukora formate ya sodium, kandi ivyo bihimba vy’umubiri vyitwa calcium oxalate bikoreshwa mu gukora aside. Ico gifungurwa c’iyunguruzo gitegurwa mu gitereko c’ivyuma bita calcium oxalate, kigaca kiyungururwa mu gitereko c’aside gifise aside sulfurique n’inzoga y’umuvyeyi y’aside oxalic yihariye, hanyuma kigacungururwa. Ico gifungurwa c’iyunguruzo (gypsum) kirasukurwa, maze amazi yo gusukura agakoreshwa mu gutegura umuti w’ivyatsi bita calcium oxalate. Ico kiyunguruzo (umunyu w’aside ya oxalic) kiranywanywa kugira ngo gikuremwo utugingo ngengabuzima dutoduto tw’aside ya calcium, kigakonja, kigahinduka ikibiriti, hanyuma kigaca gica mu nzira kugira ngo gitandukanye aside oxalic idasanzwe, iyo aside igasubira guhinduka ikibiriti, igatandukanywa, igaca yuma kugira ngo haboneke ikintu gikwiriye, maze inzoga y’umuvyeyi igasubirwamwo.
Uburyo bw’amabuye y’agaciro yitwa sodium formate lead burafise uburyo bukomeye, uburyo bw’ibicuruzwa buhamye, n’ingendo ngufi y’uguhingura, n’umwimbu w’ibice 80%–90% n’ubusuku bw’aside oxalic itunganijwe ku bice 99,5%. Ariko rero, hariho uguhumana kw’amabuye y’agaciro mu gihe c’uguhingura, kandi ivyuma vy’amabuye y’agaciro biva muri ivyo bihimba ntibishobora gusubira mu gikorwa, ni co gituma mu guhingura hakoreshwa aside nyinshi z’amazuku n’ivyuma vy’amabuye y’agaciro. Uburyo bwa calcium bwo gukora aside oxalique burashobora gukuraho ubuhumane bw’umunyu w’amabuye y’agaciro n’umunyu w’amabuye y’agaciro mu mazi yo mu butaka, kandi gusubirira soda y’umuriro n’ivu ry’umukara birashobora kugabanya cane amahera yo gukora. Igikoko c’inyuma CaSO4 kiva muri iyo nzira gishobora guhindurwa ibikoresho vy’inyubako ataco bihumanye. Muri ico gihe nyene, inzoga y’umuvyeyi NaOH ironswa mu nzira y’ugukorana ikoreshwa mu gukorana na CO kugira ngo hategurwe formate ya sodium, gutyo bikaba bizigama igitigiri c’ibikoresho vya mbere.

Asidi y'imiti y'i Shandong Pulisi: Inyungu nyamukuru
144-62-7) y’i Shandong Pulisi Chemical (≥99,6% y’ubusuku, CAS 144-62-7) igaragara cane kubera ubuhumane buke cane (sulfate ≤0,1%, ivyuma biremerera ≤0,002%, icuma ≤0,003%) n’ivyemezo vya ISO 900,MIQ-su. kwubahiriza amategeko ku masoko y’isi yose. Dushigikiwe n’imyaka 18+ y’ubuhinga bw’imiti, dutanga ibiciro vy’uruganda, ubuhinga bwo gutwara ibintu mu bikoresho vyuzuye n’ububiko mu bivuko vya Qingdao, Tianjin, Shanghai, n’ugupfunyika ibintu ku buryo bubereye (25kg/50kg) kugira ngo umuntu ashobore kubirungika hanze ata nkomanzi. Asidi yacu ya oxalic iraruta ayandi mu gutera imvura y’ivyuma bidasanzwe, gukuraho umugese w’ivyuma, gutera ibara ry’impuzu, no gusukura amabuye y’agaciro, itanga ibikorwa bihoraho n’ibisubizo biramba, bishobora gusenyuka ku baguzi b’inganda kw’isi yose.
