Enkola ya Sodium Formate eya Oxalic Acid
Okukola asidi wa oxalic mu nkola ya sodium formate kwawulwamu enkola ya lead n’enkola ya calcium. Kaboni monokisayidi ayingizibwa ekisengejjero kya sodiyamu hayidirokisayidi okusobola okufuna sodiyamu formate, oluvannyuma n’aggyibwamu haidrojeni okukola sodiyamu oxalate. Ekisembayo kikola ne lead sulfate (enkola ya lead) oba calcium hydroxide (enkola ya calcium) ne kikola lead oxalate precipitate oba calcium oxalate precipitate, oluvannyuma ne kifuulibwa asidi ne sulphuric acid okufuna oxalic acid.
Enkola ya lead ey’okukola asidi wa oxalic: Oluvannyuma lw’okunaaba, okunaaba alkali, n’okuggyawo enfuufu, kaboni monokisayidi anywezebwa okutuuka ku 2 MPa n’ekintu ekinyigiriza, n’asooka okubuguma okutuuka ku 150 °C ne 160 g/L sodium hydroxide, n’asindikibwa mu riyakita okukola ekisengejjero kya sodium formate ekitono. Ekisengejjero kisengejebwa okutuuka ku 600 g/L, ne kisindikibwa mu kkeeti y’okuggya amazzi mu mazzi okubuguma n’okusengejja ne kifuuka ekikalu, oluvannyuma ne kibuguma ne kisaanuusibwa, ne kiggyibwamu amazzi ku 400 °C. Sodium oxalate etaliimu mazzi etegekebwa mu kisengejjero, era lead sulfate n’eyongerwako wansi w’okutabulwa nga bwe kikuuma omuwendo gwa pH ku 3–4. Obucaafu obusaanuuka buggyibwawo nga bunaaba, olwo asidi wa salufuriki ayitiridde n’ateekebwamu okusobola okufuuka asidi okusobola okufuna ekisengejjero kya asidi wa oxalic. Barium carbonate ne 1% polyacrylamide ziteekebwamu okusobola okuzimba n’okutonnya okuggyawo obucaafu. Ekisengejjero kinnyogozebwa, ne kifuuka ekiristaayo, ne kisengejebwa mu ngeri ya centrifugation, ne kikalira okufuna ekintu ekiwedde.
Enkola ya kalisiyamu ey’okukola asidi wa oxalic: Ekisengejjo kya sodium oxalate ekitegekeddwa n’ekiziyiza kya kalisiyamu hayidirokisayidi bibalirirwa mu bungi ne bisindikibwa mu riyakita ya kalisiyamu okukola ensengekera ya kalisiyamu nga bitabuddwa. Amazzi agafunibwa aga calciumization gasengejebwa ne ganaazibwa. Sodiyamu hayidirokisayidi esengejeddwa esengejebwa n’ekozesebwa okukola sodiyamu formate, ate calcium oxalate eya keeki esengejeddwa ekozesebwa mu nkola y’okufuula asidi. Keeki y’okusengejja etegekebwa mu kisengejjo kya calcium oxalate, ekifuulibwa asidi mu kkeeti y’okufuula asidi ne sulphuric acid n’omwenge maama wa oxalic acid omungi, n’oluvannyuma ne gusengejebwa. Keeki y’omusengejja (gypsum) eyozebwa, era amazzi ag’okunaaba ne gakozesebwa okuteekateeka ekiziyiza kya calcium oxalate. Ekisengejjeddwa (oxalic acid solution) kinywezebwa okuggyamu obutundutundu bwa calcium sulfate obulungi, ne kinnyogozebwa, ne kifuulibwa ekiristaayo, ne kifuumuulwa okusobola okwawula asidi wa oxalic omubisi, addamu okufuuka ekiristaalo, okwawulwa, n’okukala okusobola okufuna ekintu ekituufu, era omwenge maama ne guddamu okukozesebwa.
Enkola ya sodium formate lead erina enkola ekuze, omutindo gw’ebintu ogutebenkedde, n’omutendera omumpi ogw’okufulumya, ng’amakungula ga 80%–90% ate obulongoofu bwa oxalic acid erongooseddwa bwa 99.5%. Naye waliwo obucaafu bw’omusulo mu nkola y’okufulumya, era sodium sulfate efunibwa okuva mu nsengekera eno tasobola kuzzibwa mu nkola eno, kale asidi wa salufuriki ne sooda ow’ekika kya caustic bikozesebwa mu kukola. Enkola ya calcium ey’okukola asidi wa oxalic esobola okumalawo obucaafu bw’eminnyo egy’omusulo ne sodium sulfate mu mazzi agali wansi w’ettaka, era okukyusa sooda ow’akawuka n’ossaamu lime kiyinza okukendeeza ennyo ku ssente ezisaasaanyizibwa mu kukola. Ekiva mu CaSO4 ekifunibwa okuva mu nsengekera eno kisobola okulongoosebwa ne kifuuka ebikozesebwa mu kuzimba awatali bucaafu. Mu kiseera kye kimu, NaOH ow’omwenge maama afunibwa okuva mu nsengekera ekozesebwa okukolagana ne CO okuteekateeka sodium formate, bwe kityo ne kikekkereza obungi bw’ebintu ebisookerwako.

Shandong Pulisi Chemical Oxalic Acid: Ebirungi Ebikulu
Shandong Pulisi Chemical’s oxalic acid (≥99.6% obulongoofu, CAS 144-62-7) esingako n’obucaafu obutono ennyo (sulfate ≤0.1%, ebyuma ebizito ≤0.002%, ekyuma ≤0.003%) ne ISO 9001, BV, REACH, FAMI-QS satifikeeti, okukakasa okugoberera ku butale bw’ensi yonna. Nga tuwagirwa emyaka 18+ egy’obukugu mu by’eddagala, tuwaayo emiwendo egy’obutereevu mu makolero, okutambuza ebintu mu konteyina mu bujjuvu nga tulina sitoowa okwetoloola emyalo gya Qingdao, Tianjin, Shanghai, n’okupakinga okukoleddwa ku mutindo (25kg/50kg) okusobola okutunda ebweru awatali kusosolaShandong Pulisi Chemical Group. Oxalic acid yaffe esinga mu kutonnya ebyuma ebitali bimu, okuggyawo obusagwa bw’ebyuma, okusiiga langi mu ngoye, n’okusiimuula amayinja amabajje, okutuusa omulimu ogutakyukakyuka n’okugonjoola ebizibu ebiwangaala, ebivunda mu biramu eri bakasitoma b’amakolero mu nsi yonna.
