Qhov txawv ntawm Oxalic Acid thiab Acetic Acid yog dab tsi?

Qhov txawv ntawm Oxalic Acid thiab Oxalic Acid yog dab tsi? Acetic Acid?
Yuav kom paub qhov txawv ntawm oxalic acid thiab acetic acid, peb tuaj yeem piv lawv los ntawm ntau qhov xws li xwm txheej tshuaj lom neeg, cov khoom, thiab kev siv tau. Txawm hais tias ob qho tib si koom nrog cov organic acids, qhov sib txawv ntawm lawv cov qauv thiab cov yam ntxwv ua rau muaj kev coj cwj pwm sib txawv hauv xwm, cov tshuaj lom neeg, thiab kev siv tib neeg.

Ua ntej, cia peb saib lawv cov tshuaj lom neeg.
Oxalic acid, uas yog tshuaj lom neeg hu ua ethanedioic acid, muaj ob pawg carboxyl (-COOH) hauv nws cov qauv molecular, nrog rau cov mis molecular H₂C₂O₄. Nws zoo li ib lub molecule nqa ob pawg acidic, npaj txhij tso ob lub hydrogen ions.

Acetic acid, tseem hu ua ethanoic acid, tsuas muaj ib pawg carboxyl xwb, nrog rau cov mis molecular CH₃COOH. Nws cov molecule zoo li "tus neeg taug kev ib leeg" nrog ib pawg acidic. Qhov sib txawv ntawm cov qauv molecular no, zoo li lawv "genetic code", txiav txim siab txog ntau yam kev sib txawv ntawm tus cwj pwm tom qab.

Qhov kev qhia ncaj qha tshaj plaws ntawm qhov "qhov sib txawv ntawm caj ces" no yog lub zog acid.
Oxalic acid yog ib qho diprotic muaj zog acid uas tuaj yeem ionize hydrogen ions hauv cov kauj ruam hauv cov kua dej, ua rau nws cov acidity muaj zog dua li ntawm acetic acid.

Acetic acid yog ib qho monoprotic weak acid; tsuas yog qee qhov ntawm nws cov molecules ionize hauv dej, ua rau muaj acidity me ntsis.
Peb tuaj yeem xav txog oxalic acid ua ib tug tub hluas uas muaj zog thiab teb tau sai, thaum acetic acid zoo li ib tug neeg laus uas muaj lub siab mos siab muag thiab tsis nyiam ua phem.

Hais txog cov khoom siv tshuaj lom neeg, vim muaj kev sib txuas ncaj qha ntawm nws ob pawg carboxyl, oxalic acid muaj zog txo qis. Nws yooj yim oxidized los ntawm cov neeg sawv cev oxidizing (xws li potassium permanganate) los tsim cov pa roj carbon dioxide thiab dej. Cov yam ntxwv no ua rau oxalic acid feem ntau siv ua tus neeg sawv cev txo qis hauv kev tshuaj ntsuam tshuaj.

Qhov sib piv, cov qauv molecular ntawm acetic acid yog qhov ruaj khov, feem ntau tsis yooj yim oxidized, muab nws cov tshuaj lom neeg "ruaj khov".
Tsis tas li ntawd xwb, thaum oxalic acid cuam tshuam nrog qee cov hlau ions (xws li calcium ions), nws tsim cov calcium oxalate precipitates uas tsis yaj zoo hauv dej, uas yog ib qho ntawm cov khoom tseem ceeb ntawm pob zeb hauv lub raum.
Los ntawm kev sib piv, cov acetates tsim los ntawm kev sib xyaw ntawm acetic acid nrog calcium ions thiab lwm yam tshuaj feem ntau yooj yim yaj hauv dej.

Nyob rau hauv cov nqe lus ntawm qhov tshwm sim thiab kev siv, txhua tus muaj nws tus kheej lub hom phiaj.
Oxalic acid pom muaj ntau hauv ntau cov nroj tsuag hauv xwm, xws li spinach, amaranth, thiab rhubarb. Qhov no yog vim li cas nws thiaj li pom zoo kom blanch cov zaub no ua ntej noj kom tshem tawm ib feem ntawm oxalic acid. Nws muaj ntau yam kev siv hauv kev lag luam, suav nrog kev tshem tawm xeb, textile bleaching, thiab kev sib cais thiab kev ntxuav cov hlau tsis tshua muaj. Txawm li cas los xij, vim nws muaj qee yam tshuaj lom thiab corrosivity, yuav tsum tau ceev faj ntxiv thaum siv nws.

Acetic acid yog ib qho ntawm cov organic acids uas peb paub zoo tshaj plaws hauv peb lub neej txhua hnub. Nws yog cov khoom tseem ceeb ntawm cov kua txiv hmab, ua rau cov kua txiv hmab saj qaub. Hauv kev lag luam khoom noj, acetic acid siv los ua cov tshuaj acidulant thiab preservative; hauv kev lag luam tshuaj lom neeg, nws yog ib qho khoom siv tseem ceeb rau kev tsim cov vinyl acetate, acetate fibers, thiab ntau ntxiv. Vim nws cov acidity me me thiab muaj tshuaj lom tsawg heev (hauv qhov ntau thiab tsawg uas siv tau), acetic acid siv dav dua thiab muaj kev nyab xeeb dua hauv kev lag luam khoom noj thiab tshuaj.

Oxalic Acid - Zibo Anhao Chemical Co., Ltd.
Zibo Anhao Chemical Co., Ltd. yog ib lub tuam txhab tsim khoom thiab muag khoom zoo hauv Suav teb, nyob hauv Zibo, Shandong—lub plawv nroog ntawm kev lag luam tshuaj lom neeg hauv Suav teb. Peb cov oxalic acid muaj nyob rau hauv anhydrous (≥99.5%) thiab dihydrate (≥99.0%), zoo li hmoov dawb crystalline nrog cov khoom siv tshuaj ruaj khov, tsis muaj dej noo, thiab tsis muaj kuab paug ntau.

Tsim los ntawm kev tswj hwm zoo thiab cov qauv hauv tebchaws, peb cov oxalic acid muaj zog txo qis thiab muaj peev xwm chelating zoo heev, siv dav hauv kev zas xim textile (mordant / bleaching), kev kho hlau (tshem tawm xeb / electroplating), rho tawm cov av tsis tshua muaj, organic synthesis, tawv tanning, thiab kev tsim tshuaj & agrochemical. Txhua pawg tau kuaj xyuas tag nrho thiab nrog COA, MSDS, thiab lwm cov ntaub ntawv ua raws li kev cai kom tau raws li kev thov kev lag luam thoob ntiaj teb.

Peb muaj ntau xyoo ntawm kev xa khoom mus rau txawv teb chaws Es Xias, Tebchaws Europe, Middle East, thiab lwm qhov chaw, peb muab cov khoom ntim khoom yooj ywm (25kg hnab), tus nqi sib tw, thiab cov nqe xa khoom txhim khu kev qha (FOB/CIF/DDP). Txawm yog rau kev txiav txim me me lossis kev muab khoom ntau, Zibo Anhao Chemical muab cov khoom zoo sib xws, kev muab khoom ruaj khov, thiab cov kev daws teeb meem tshwj xeeb los txhawb koj txoj kev loj hlob ntawm kev lag luam.
