Enkola y’okuyunga Oxalic Acid Carbon Monoxide
Enkola eno mu kusooka yakozesa eminnyo gya palladium n’ekikomo nga ebiziyiza, era n’ekola enkola y’okuyunga amazzi (liquid-phase coupling reaction) eya kaboni monokisayidi, okisigyeni, omwenge, ne asidi wa nayitiriki omutono ku 8–11 MPa ne 90–100 °C. Enzirukanya eno esooka kukola oxalate ester, oluvannyuma n’efuuka hydrolyzed mu mbeera y’ebbugumu okukola asidi oxalic n’omwenge ogukwatagana.
Enkola eno erina enkola emu ey’ekirungo ekiziyiza, emirimu mingi, okulonda okulungi, okwangu okuddamu, obulongoofu bw’ebintu obw’amaanyi, n’obucaafu obutono obukolebwa. Wabula erina ebyetaago bingi eby’obulongoofu bwa kaboni monokisayidi, ekozesebwa nnyo, ebiziyiza eby’ebbeeyi, n’okuteeka ssente nnyingi.
Nga tukozesa Pd/C nga ekirungo ekiziyiza, kaboni monokisayidi ne nitrite ester biyungibwa okukola oxalate ester ku 130 °C ne puleesa y’empewo, nga nitric oxide y’ekivaamu. Asidi wa oxalic n’omwenge ogukwatagana nayo bifunibwa nga tusengejja oxalate ester mu mazzi. Ekisengejjo ky’omwenge ekyawuddwamu kiddamu okufuuka okisigyeni ne kikola nitrite ester, ekiyinza okuddamu okukozesebwa.
Ekitongole kya Fujian Institute of Structure of Matter, Chinese Academy of Sciences, kikoze okunoonyereza ku mugerageranyo gw’ebintu ebisookerwako n’embeera ez’enjawulo ez’embiro z’omu bwengula ku nkola y’okusengejja dimethyl oxalate mu kunoonyereza ku biziyiza okuyunga CO ku asidi wa oxalic mu puleesa y’empewo, n’okulonda embeera z’ensengekera ezisaanira. Ekirungo ekirongooseddwa ekya Pd (2.0%)/α-Al2O3 kyatuuka ku makungula g’omu bwengula g/L·h wansi w’embeera ya puleesa y’empewo, 140 °C, CO/CH3ONO=1.5, n’embiro z’omu bwengula eza 3000/h. Ettendekero lino lyakolagana n’ekitongole kya Fujian Petrochemical Design Institute ne Fujian Nanqing Ammonia Plant okukola okugezesa okw’okugezesa okuzza CO okuva mu kusenya ekikomo kya ammonia ekikoleddwa, okukola dimethyl oxalate mu puleesa y’empewo, n’okusengejja amazzi okutuuka ku asidi wa oxalic.
Bw’ogeraageranya n’enkola ya liquid-phase, enkola eno erina okulonda okw’amaanyi, enkola ennyangu, obulongoofu bw’ebintu obw’amaanyi, n’omuwendo omutono ogw’okufulumya. Kiyinza okukozesa ggaasi ow’obutonde oba amanda ng’ebigimusa, era kisobola n’okukozesa kaboni monokisayidi azuuliddwa okuva mu kikomo kya ammonia oba ekikoomi kya phosphorus ekya kyenvu, ekikoomi ekinene, ne ggaasi w’omukira ogukyusa ng’ensibuko ya ggaasi wa kaboni monokisayidi. Mu kiseera kye kimu, esobola okuwa ebigimusa ebya layisi okukola ethylene glycol n’okusengejja okugatta ne oxalate ester ng’ekirungo eky’omu makkati.

Shandong Pulisi Kkampuni y'eddagala | Omugabi wa Oxalic Acid ow’omutindo ogwa waggulu
Pulisi Chemical yatandikibwawo mu 2006, yakuguka mu kukola asidi wa oxalic ow’obulongoofu obw’amaanyi (CAS 144-62-7) ng’egoberera omutindo gw’ensi yonna ogw’okutunda ebweru w’eggwanga ku ddaala ly’amakolero n’eryalongooseddwa. Ekifo kyaffe eky’amakolero ekyesigamiziddwa ku Zibo kikakasa okulondoola omutindo mu ngeri enkakali, nga asidi wa oxalic ow’omutindo gw’amakolero yeewaanira ku bulongoofu obutakka wansi wa 96% ate ow’omutindo ogulongooseddwa atuuka ku bulongoofu bwa bitundu 99.6% —nga atuukiriza ebisaanyizo by’amakolero eby’enjawulo.
Oxalic acid yaffe esingako olw’okusaanuuka obulungi n’eddagala erinywevu, ng’akola ng’ekintu ekisookerwako ekikola emirimu mingi mu bitundu byonna. Mu kukola ebyuma, eggyawo bulungi obusagwa ne layers za oxide ez’okungulu okuva mu kyuma, aluminiyamu, n’ekikomo, n’eyongera ku kwekwata kw’okusiiga okukozesebwa mu mmotoka, mu bwengula, n’okusiiga amasannyalaze. Mu ngoye, ekola ng’ekirungo ekiziyiza obutonde bw’ensi n’okunyweza langi, okulongoosa langi y’olugoye okunyweza n’okumasamasa.
Okugatta ku ekyo, ekozesebwa nnyo mu kukola eddagala, okulongoosa enku, okuggya ebyuma ebitali bimu, n’okulongoosa amazzi. Nga tukakasiddwa ne ISO 9001 ne EU REACH, tugaba ebipapula ebituufu ebya kkiro 25 ku orders ennyingi, okukakasa nti tugaba ebintu ebyesigika mu nsi yonna. Ka kibeere okufulumya amakolero amanene oba okukozesa eby’omulembe, Pulisi Chemical etuwa omutindo ogutaggwaawo n’obuyambi obw’ekikugu.
