Ethylene Glycol Nitric Acid Oxidation Txoj Kev ntawm Oxalic Acid
Cov txheej txheem oxidation no zoo ib yam li txoj kev oxidation hmoov txhuv nplej siab. Cov kua dej ethylene glycol raug cua sov rau 60 ° C, thiab cov kua qaub sib xyaw (30% -40% sulfuric acid los ntawm qhov hnyav, 20% -25% nitric acid los ntawm qhov hnyav) thiab vanadium pentoxide raug ntxiv rau hauv qab kev sib xyaw ua ke. Kev oxidation yog nqa tawm ntawm 50-70 ° C thiab 1.3-4.0 kPa. Cov khoom raug txias, crystallized, thiab lim kom tau txais oxalic acid nrog qhov huv ntawm 99.9% thiab cov txiaj ntsig ntawm ntau dua 90%. Txoj kev no tuaj yeem ua tiav hauv peb qhov xwm txheej txheej txheem: qhov siab ntawm huab cua, txo qhov siab, thiab nce qhov siab. Nws muaj cov txheej txheem yooj yim, cov txiaj ntsig oxalic acid siab, cov khoom zoo, thiab yuav luag tag nrho rov qab los ntawm nitric acid, tab sis tus nqi khoom siv raw siab.

Shandong Pulisi Chemical Co., Ltd. Oxalic Acid Dihydrate - Qib Muaj 99.6% Purity
Shandong Pulisi Chemical Co., Ltd., yog ib lub tuam txhab tsim tshuaj lom neeg thiab xa tawm txij li xyoo 2006, tshwj xeeb hauv kev tsim cov tshuaj oxalic acid dihydrate uas muaj kev ntshiab siab (H₂C₂O₄·2H₂O, CAS 6153-56-6, EINECS 205-634-3) nrog kev tswj hwm zoo. Peb cov oxalic acid qib kev lag luam muaj qhov huv tsawg kawg nkaus ntawm 99.6%, zoo li hmoov crystalline dawb nrog cov qib tsis huv qis (sulfate ≤0.1%, hlau hnyav ≤0.002%, hlau ≤0.003%). Nws yog siv dav hauv kev luam ntawv thiab zas xim, kev ua tawv nqaij, kev ntxuav qhov chaw hlau, kev txhuam marble, kev kho dej, kev rho tawm cov av tsis tshua muaj, thiab kev tsim tshuaj nruab nrab.
Peb muaj cov khoom muag ntau heev hauv peb lub tsev rau khoom hauv Shandong, ua rau peb xa khoom tau sai rau cov neeg yuav khoom ntau. Cov kev xaiv ntim khoom yooj ywm (25kg, 50kg, 1000kg hnab) thiab kev xa khoom thoob ntiaj teb los ntawm Qingdao, Tianjin, lossis Shanghai chaw nres nkoj ua kom xa khoom tau raws sijhawm thoob ntiaj teb. Peb muab kev txhawb nqa kev siv tshuab tag nrho, cov ntaub ntawv COA/MSDS, thiab tus nqi sib tw kom tau raws li ntau yam kev xav tau ntawm kev lag luam.
Tiv tauj peb hnub no rau kev hais nqe tshwj xeeb thiab ruaj ntseg koj cov saw hlau oxalic acid.
