Uburyo bwo guhuza aside oxalic monoxide karuboni
Ubu buryo bwabanje gukoresha umunyu wa palladium n'umuringa nk'ibikatakata, kandi bwakoze uburyo bwo guhuza umwuka wa monoxide karubone, ogisijeni, alcool, na aside nitrike ku bushyuhe bwa 8-11 MPa na 90-100 °C. Uburyo bwa mbere butanga oxalate ester, hanyuma igashyirwamo hydrolyze mu gihe cy'ubushyuhe kugira ngo ikore aside oxalic na alcool ijyanye nayo.
Ubu buryo bufite sisitemu imwe ya catalyst, ibikorwa byinshi, guhitamo neza, kugarura byoroshye, isuku y'ibicuruzwa byinshi, n'umwanda muke w'umusaruro. Ariko, bufite ibisabwa byinshi kugira ngo monoxyde de carbone ibe nziza, ikoreshwa cyane, catalyst ihenze, ndetse n'ishoramari rinini.
Hakoreshejwe Pd/C nk'umusemburo, monoxyde ya karuboni na ester ya nitrite bihuzwa kugira ngo bikore ester ya oxalate kuri 130 °C n'umuvuduko w'ikirere, hamwe na oxyde ya nitrite nk'umusaruro ukomoka kuri iyo. Aside ya oxalate na alcohol bijyana nayo biboneka binyuze mu gushonga ester ya oxalate. Umuti wa alcohol watandukanyijwe usubizwamo oxidized kugira ngo habeho ester ya nitrite, ishobora kongera gukoreshwa.
Ikigo cya Fujian Institute of Structure of Matter, Ishuri Rikuru ry’Ubumenyi ry’Abashinwa, cyakoze ubushakashatsi ku gipimo cy’ibikoresho fatizo n’imiterere itandukanye y’umuvuduko w’ikirere ku bijyanye no gukora dimethyl oxalate mu bushakashatsi ku bintu bitera imbaraga mu guhuza CO na aside oxalate, kandi cyahisemo imiterere ikwiye yo gukora. Pd (2.0%)/α-Al₂O₃ catalyst yazamutseho umusaruro wa 999 g/L·h mu gihe cy’umuvuduko w’ikirere, 140 °C, CO/CH₃ONO=1.5, n’umuvuduko w’ikirere wa 3000/h. Ikigo cyafatanyije n’Ikigo gishinzwe Gushushanya Petrochemical cya Fujian na Fujian Nanqing Ammonia Plant kugira ngo bakore ikizamini cya 100 t/a cyo kugarura CO mu muringa wa amoniya ukozwe mu buryo bwa synthetic, gukora dimethyl oxalate mu buryo bwa catalytic mu kirere, no gukoresha hydrolysis muri aside oxalate.
Ugereranyije n'uburyo bwo gukoresha amazi mu gice cy'amazi, ubu buryo bufite ubushobozi bwo guhitamo ibintu byinshi, uburyo bworoshye bwo gukora, ubuziranenge bw'ibicuruzwa buri hejuru, kandi bufite ikiguzi gito cyo gukora. Bushobora gukoresha gazi karemano cyangwa amakara nk'ibikoresho fatizo, kandi bushobora no gukoresha gazi karubone yakuwe muri ammonia copper scrubbing cyangwa phosphore y'umuhondo, blast furnace, na converter tail gaze nk'isoko ya gazi karubone monoxyde. Muri icyo gihe, bushobora gutanga ibikoresho fatizo bihendutse byo gukora ethylene glycol no guhuza na oxalate ester nk'intera.

Shandong Pulisi Chemical Co., Ltd. | Umutanga aside oxalic nziza
Yashinzwe mu 2006, Pulisi Chemical inzobere mu gupima aside oxalic nziza cyane (CAS 144-62-7) ikurikije amahame mpuzamahanga yo kohereza ibicuruzwa mu mahanga haba mu nganda no mu nganda zitunganijwe neza. Uruganda rwacu rukorera muri Zibo rugenzura neza ubuziranenge, aho aside oxalic nziza cyane ifite ubuziranenge bwa 96% n'ubuziranenge bugera kuri 99.6% - ihuye n'ibisabwa bitandukanye mu nganda.
Aside yacu ya oxalic iratandukanye cyane kubera ubushobozi bwayo bwo gushonga no kudahindagurika mu binyabutabire, ikaba ikoreshwa mu buryo butandukanye mu nzego zitandukanye. Mu gutunganya ibyuma, ikuraho neza ingese n'ibice bya okiside byo hejuru mu byuma, aluminiyumu na umuringa, yongera uburyo bwo gufatana kw'ibirahure mu modoka, mu kirere no mu bikoresho bya elegitoroniki. Mu myenda, ikora nk'ikintu gihumanya ibidukikije kandi gishyiraho irangi, ikongera ubushyuhe n'urumuri ku myenda.
Byongeye kandi, ikoreshwa cyane mu gukora imiti, gutunganya ibiti, gucukura ibyuma bidasanzwe, no gutunganya amazi. Ifite icyemezo cya ISO 9001 na EU REACH, itanga amapaki apima ibiro 25 ku bicuruzwa byinshi, bigatuma habaho serivisi zizewe ku isi yose. Haba mu nganda nini cyangwa mu bikorwa byo ku rwego rwo hejuru, Pulisi Chemical itanga ubufasha buhamye kandi bw’umwuga.
