Laawol jokkondire asid oksalik monoksiid karbon
Ndee feere fuɗɗii huutoraade ko salte paladium e njamndi ngam waɗde katalis, e waɗde feere jokkondire faɗo ndiyam hakkunde monoksiid karbonik, oksijen, alkol, e asid nitriik ɓuuɓɗo e 8–11 MPa e 90–100 °C. Reaksiyoŋ oo adii waɗde ko ester oksalaat, caggal ɗuum o ɓuuɓna e nder nguleeki ngam waɗde asid oksalaat e alkol nannduɗo e mum.
Ndee feere ina jogii mbaydi katalis gooto, golle toowɗe, suɓagol moƴƴol, ƴellitgol weeɓngol, laaɓal geɗel toowngal, e pollugol peewnugol seeɗa. Kono tan, ina jogii sarɗiiji toowɗi ngam laaɓal gaas karbonik, njaru toowngu, katalisuuji caɗtuɗi, e njulaagu mawngu.
Huutoraade Pd/C ngam waɗde katalis, monoksiid karbonik e esteer nitriit ina kawree ngam sinkude esteer oksalaat e 130 °C e nguleeki weeyo, tawa oksidaa nitriit ko huunde nde alaa ko woni e mum. Asid oksalik e alkol ko nanndi heen ina keɓee e ɓuuɓnude esteer oksalaat. Kosam alkol seertuɗam ɗam ina ɓuuɓnee ngam waɗde esteer nitrite, baawɗo huutoreede.
Duɗal Fujian to bannge mbaydi huunde, Akademi ganndal Siin, waɗii wiɗtooji ko faati e njuuteendi geɗe mbaylaandi e ngonkaaji njaaweeki weeyo ceertuɗi e dow sintesis katalitik dimetil oksalaat e nder wiɗtooji katalitik ngam jokkondire katalitik cuɓaaɗo e CO e asid oksalik cuɓaaɗo, e. Katalis Pd (2,0%)/α-Al2O3 moƴƴinaaɗo oo heɓiino ƴellitaare weeyo-waktu 999 g/L·h e nder ngonkaaji ɓuuɓol weeyo, 140 °C, CO/CH3ONO=1,5, e njaaweeki weeyo 3000/h. Duɗal ngal gollondirii e Duɗal Diisnondiral Petrokimikal Fujian e Fujian Nanqing Ammoniak Plant ngam waɗde jarribo jarriborgo 100 t/a ngam heɓtude CO e nder ɓuuɓri njamndi amoniak sintetik, sintesis katalitik e dow weeyo dimetil oksalaat, e hidrolisis asid oksa haa.
So en tuugniima e feere fasaade ndiyam, ndee feere ina jogii suɓagol toowngol, golle koyɗe, laaɓal geɗe toowɗe, e njoɓdi peewnugol tokosiri. Ina waawi huutoraade gaasuuji tawaaɗi walla kuuraa ngam waɗde geɗe mbaylaandi, ina waawi kadi huutoraade gaas karbonik keɓaaɗo e ɓuuɓri njamndi mboɗeeri amoniak walla ɓuuɓri fosfaat oole, ɓuuɓri ɓuuɓndi, e gaas wutte waylo-waylo ngam waɗde ɗum ɓuuɓri gaas karbonik. E oon sahaa gooto, ina waawi rokkude kaɓirɗe keewɗe ngam peewnugol etilen glikol e sintesis gooto e esteer oksalaat ko hakkundeejo.

Koolaaɗo kuuɓal kemikal Pulisi Shandong | Dokkoowo asid oksalik ɓurɗo moƴƴude
Sosaa ko e hitaande 2006, Pulisi Chemical ina teskii asid oksalik laaɓtuɗo (CAS 144-62-7) jowitiiɗo e sarɗiiji njulaagu winndereeji wonande toɓɓe gollorɗe e toɓɓe laaɓtuɗe. Men Zibo-based peewnugol nokku ina tabitina ƴeewndo tiiɗngo kalite, e asid oksalik-grade industriel manti ko famɗi fof 96% laaɓal e refined-grade yettaade 99.6% laaɓal—jokkondirde e sarɗiiji gollorɗi ceertuɗi.
Asid men oksalik ina seerti e ɓuuɓri mum moƴƴiri e sifaaji mum kemikal dartiiɗi, ina waɗi geɗe keewɗe e nder sekteeruuji. E nder golle njamndi, ina itta no moƴƴi ɓuuɓri e laylayti oksidaaji dowri e njamndi, aluminium, e njamndi, ɓeyda jokkondire coating ngam otooji, aerospace, e electroplating kuutorɗe. E nder mbaydiiji, ina waɗi ko wayi no mbaydi ɓuuɓndi e mbaydi mbaylaandi, ina moƴƴina yaawre e jalbugol mbaydiiji mbaydiiji.
Yanti heen, ina huutoree no feewi e sintesis farmasi, e peewnugol leɗɗe, e ƴettugol njamndi mboɗeeri, e safrude ɓuuɓri ndiyam.
