I-Ethylene Glycol Nitric Acid Oxidation Indlela ye-Oxalic Acid
Ikambiso yokwenza i-oksijini ifana khulu nendlela yokwenza i-oksijini yesitashi. Isisombululo se-ethylene glycol esinamanzi sitjhiswa sibe ku-60 °C, bese kuthi i-asidi ehlanganisiweko (30%–40% ye-sulphuric acid ngobukhulu, 20%–25% ye-nitric acid ngobukhulu) kanye ne-vanadium pentoxide kufakwa ngaphasi kokuvuselela okunamandla. Ukukhiqizwa kwe-oksijini kwenziwa ku-50-70 °C kanye ne-1.3-4.0 kPa. Umkhiqizo uyapholiswa, ube yikristalu, begodu uhlungwe ukuthola i-oxalic acid enobumsulwa obungu-99.9% kanye nokukhiqiza okungaphezu kwama-90%. Indlela le ingenziwa ngaphasi kwemibandela emithathu: umfutho womkhathi, umfutho ophasi, kanye nomfutho okhuphukileko. Inendlela elula, isivuno esiphezulu se-oxalic acid, ikhwalithi ehle yomkhiqizo, kanye nokubuyiselwa okupheleleko kwe-nitric acid, kodwana intengo yezinto ezisetjenziswako iphezulu.

I-Shandong Pulisi Chemical Co., Ltd. I-Oxalic Acid Dihydrate – Izinga lezebubulo eliyi-99.6% yokuhlanzeka
I-Shandong Pulisi Chemical Co., Ltd., umkhiqizi wamakhemikhali othembekileko nomthumeli ngaphandle kusukela ngo-2006, ukhethekile ekukhiqizeni i-oxalic acid dihydrate (H₂C2O₄·2H2O, CAS 6153-56-6, EINECS 2053-63) ngokulawula okuqinileko. I-oxalic acid yethu yezinga lebubulo inobumsulwa obuncani obungu-99.6%, ibonakala njengepuyere emhlophe enamazinga aphasi wokungcola (i-sulfate ≤0.1%, iinsimbi ezisindako ≤0.002%, insimbi ≤0.003%). Isetjenziswa khulu ekugadangiseni iingubo nokudaya, ukucubungula isikhumba, ukuhlanza indawo yensimbi, ukupholisa imabula, ukuhlanza amanzi, ukukhipha inarha engakajayeleki, kanye nokuhlanganiswa kwemithi.
Sigcina izinto ezinengi ezisesitokweni esitokisini sethu se-Shandong, okwenza bona kuthunyelwe msinyana ama-oda amanengi. Iindlela zokupaka eziguquguqukako (25kg, 50kg, 1000kg izikhwama) nokuthunyelwa kwephasi loke ukusuka e-Qingdao, Tianjin, nofana amatheku we-Shanghai kuqinisekisa ukulethwa ngesikhathi ephasini loke. Sinikela ngesizo elizeleko lobuthekhnikhi, imitlolo ye-COA/MSDS, kanye neentengo eziphalisanako ukuhlangabezana neendingo ezihlukahlukeneko zebubulo.
Xhumana nathi namhlanjesi ukuthola ikhowuthi eyenziwe ngokwezifiso begodu uvikele ithungelelwano lakho lokuphakelwa kwe-oxalic acid.
