Oxalicacid CAS: 144-62-7

Oxalic acid ua haujlwm ua ib qho tseem ceeb hauv kev ntxuav thiab npaj cov hlau nto, qhov twg nws lub peev xwm tshem tawm xeb, nplai, thiab cov khoom siv hauv cov hlau ua rau nws muaj txiaj ntsig zoo hauv kev txij nkawm kev lag luam, kev kho hlau, thiab cov txheej txheem kho hlau nto. Nws daim ntawv thov pab txhawb rau kev txhim kho kev tiv thaiv xeb hlau, qhov tiav ntawm qhov chaw, thiab cov khoom nplaum, txhawb nqa kev tsim cov khoom lag luam hlau zoo thoob plaws ntau yam kev lag luam. Hauv kev ua cov ntaub, oxalic acid ua haujlwm ua cov tshuaj dawb, mordant, thiab pH adjuster, txhawb nqa kev dawb thiab dyeing ntawm cov fibers ntuj xws li paj rwb thiab ntaub plaub. Nws lub luag haujlwm hauv cov txheej txheem no pab txhawb rau kev tshem tawm cov khoom tsis huv, kev txhim kho ntawm kev nqus xim, thiab kev ua tiav ntawm cov xim xav tau hauv cov ntaub ntawv textile, txhawb nqa kev tsim cov ntaub ci ntsa iab thiab sib xws rau cov khaub ncaws, rooj tog hauv tsev, thiab kev siv hauv kev lag luam. Ntxiv mus, oxalic acid yog siv rau hauv kev tsim cov tshuaj intermediates thiab cov tshuaj zoo, txhawb nqa kev tsim cov khoom xyaw tshuaj nquag (APIs) thiab cov organic molecules nyuaj. Nws lub luag haujlwm hauv kev tsim cov tshuaj ua rau muaj kev tsim cov pa roj carbon-carbon zoo thiab tsim cov tshuaj muaj txiaj ntsig rau kev kho mob tshuaj, agrochemicals, thiab kev siv tshuaj tshwj xeeb, pab txhawb rau kev nce qib hauv kev tshawb pom tshuaj thiab kev tshawb fawb txog cov khoom siv. Tsis tas li ntawd, oxalic acid pom tias siv ua tus neeg sawv cev chelating thiab tshem tawm cov nplai hauv cov txheej txheem kho dej hauv kev lag luam, qhov twg nws lub peev xwm los cais cov hlau ions thiab yaj cov nplai tso tawm txhawb nqa kev tiv thaiv kev nplai, xeb, thiab fouling hauv cov kab ke dej, boilers, thiab cov cua sov hloov pauv, pab txhawb rau kev ua haujlwm zoo thiab kev saib xyuas cov khoom siv hauv kev lag luam thiab cov khoom siv hauv paus. Tsis tas li ntawd, oxalic acid yog siv rau hauv kev tsim cov khoom siv ntxuav hauv tsev, cov tshuaj tshem xeb, thiab cov tshuaj dawb ntoo, qhov twg nws cov kua qaub thiab txo cov khoom txhawb nqa kev tshem tawm cov xim, kev hloov pauv, thiab kev puas tsuaj los ntawm ntau qhov chaw, suav nrog hlau, ntoo, thiab ceramics. Nws siv txhim kho kev ntxuav thiab kev kho dua tshiab ntawm cov khoom hauv tsev thiab cov ntaub ntawv tsim kho, pab txhawb rau kev saib xyuas thiab kev kho dua tshiab hauv cov chaw nyob thiab kev lag luam. Oxalic acid kuj ua haujlwm ua tus neeg sawv cev hauv kev ci thiab ua cov khoom xyaw tseem ceeb hauv qee cov khoom siv tshem xeb hauv tsev vim nws cov khoom siv yaj xeb zoo. Zuag qhia tag nrho, ntau yam kev siv ntawm oxalic acid hauv kev ntxuav hlau, kev ua cov ntaub, kev tsim tshuaj lom neeg, kev kho dej, kev ntxuav tsev neeg, thiab kev siv ua noj ua haus qhia txog nws qhov tseem ceeb ua ib qho khoom sib xyaw ua ke nrog kev siv dav hauv ntau qhov kev lag luam, pab txhawb rau kev nce qib hauv cov khoom siv thev naus laus zis, kev saib xyuas kev lag luam, thiab cov khoom siv rau cov neeg siv khoom.
