Oxalic Acid 99.6% feeb
Lub cev, Oxalic acid tshwm sim ua cov phaj monoclinic tsis muaj xim lossis cov siv lead ua prismatic, lossis hmoov dawb. Oxalic acid tsim los ntawm cov txheej txheem oxidation tsis muaj ntxhiab, thaum qhov ntawd los ntawm cov txheej txheem synthesis yuav muaj ntxhiab tsw txawv. Nws sublimes ntawm 150–160 ° C thiab effloresces hauv huab cua kub, qhuav. Nws cov ntaub ntawv solubility yog qhov zoo-txhais: 1 g yaj hauv 7 mL dej, 2 mL dej npau, 2.5 mL ethanol, 1.8 mL ethanol npau, 100 mL ether, lossis 5.5 mL glycerol, tab sis tsis yaj hauv benzene, chloroform, thiab roj av ether. Ib qho tshuaj 0.1 mol / L muaj pH ntawm 1.3. Nws qhov ceev sib piv (ntawm 18.54 ° C) yog 1.653, nrog rau qhov chaw yaj ntawm 101–102 ° C (rau dihydrate) lossis 187 ° C (daim ntawv anhydrous). Nws yog cais ua cov tshuaj lom tsawg, nrog rau dermal LD₅₀ (luav) ntawm 2000 mg / kg.
Zibo Anhao Chemical Co., Ltd. - Oxalic Acid (Dihydrate) Uas Muaj Peev Xwm Siab
Zibo Anhao Chemical Co., Ltd. yog ib lub tuam txhab Suav teb uas muab khoom thiab xa tawm cov kua qaub oxalic acid (H₂C₂O₄·2H₂O, dihydrate) uas muaj lub hauv paus nyob hauv Zibo, xeev Shandong, uas yog lub hauv paus tshuaj tseem ceeb nyob rau sab qaum teb Suav teb. Peb cov kua qaub oxalic acid yog tsim los ntawm kev tswj hwm zoo, nrog rau qhov huv huv ntawm 99.6% min, cov dej noo tsawg, thiab cov qauv crystalline ruaj khov, ua kom ntseeg tau tias cov neeg siv khoom lag luam thoob ntiaj teb ua haujlwm tau zoo tas li.
Peb cov oxalic acid ua haujlwm ua cov organic acid ntau yam uas siv dav hauv kev ua kom dawb ntawm cov ntaub, kev tanning tawv, kev kho qhov chaw ntawm hlau, kev txhuam marble, kev rho tawm cov av tsis tshua muaj, thiab kev tsim cov tshuaj organic. Nws ua haujlwm ua tus neeg sawv cev descaling, tshem tawm xeb, thiab txo cov neeg sawv cev, txhawb kev tsim khoom zoo hauv ntau yam lag luam.
Nrog ntau tshaj 10 xyoo ntawm kev paub txog kev xa tawm tshuaj lom neeg, Anhao Chemical muab cov ntim khoom yooj ywm (25kg hnab lossis kho kom haum), muaj peev xwm muab khoom ruaj khov, thiab kev txhawb nqa cov ntaub ntawv tshaj lij kom ua tau raws li cov qauv thoob ntiaj teb. Peb muab qhov tseem ceeb rau kev koom tes mus sij hawm ntev thiab xa cov khoom zoo sib xws ntawm cov nqi sib tw.
