Acetic acid, tseem hu ua Glacial acetic acid, nws yog ib qho organic compound nrog cov tshuaj formula CH3COOH, uas yog lub ntsiab ntawm vinegar.Acetic acid yog ib tug tsis muaj kob thiab pob tshab kua nrog ib tug pungent tsw, soluble nyob rau hauv dej, ethanol, ether, glycerin. , thiab insoluble hauv carbon disulfide.Nws yog feem ntau tam sim no nyob rau hauv ntau yam nroj tsuag nyob rau hauv cov xwm nyob rau hauv dawb los yog ester daim ntawv.Lub Glacial acetic acid yuav muab faib ua zaub mov qib glacial acetic acid thiab industrial qib glacial acetic acid.
Kev siv glacial acetic acid hauv kev lag luam:
Acetic acid yog cov khoom lag luam tseem ceeb thiab ib qho tseem ceeb ntawm cov organic acids.Feem ntau yog siv hauv kev tsim cov acetic anhydride, acetate thiab cellulose acetate.
Acetates tsim los ntawm qis cawv yog cov kuab tshuaj zoo heev thiab tau siv dav hauv kev lag luam xim.Acetic acid kuj yog ib qho nquag siv cov kuab tshuaj organic vim nws dissolves feem ntau cov organics.
Acetic acid tuaj yeem siv rau hauv qee qhov kev daws teeb meem thiab polishing, raws li qhov tsis muaj nyob hauv cov kua qaub tsis muaj zog, ua ib qho ntxiv hauv ib nrab ci npib tsib xee plating electrolytes, thiab nyob rau hauv passivation kev daws teeb meem ntawm zinc thiab cadmium los txhim kho lub binding quab yuam ntawm passivation films, Nws yog. feem ntau siv los kho cov pH ntawm cov dej tsis muaj zog acidic.
Acetic aicd yog siv rau hauv kev tsim cov acetate, xws li manganese, sodium, lead, txhuas, zinc, cobalt thiab lwm yam hlau ntsev, dav siv los ua catalyst, ntaub dyeing thiab tawv tanning kev lag luam auxiliaries;lead acetate yog xim xim hlau lead dawb;Lead tetraacetate yog cov organic hluavtaws reagent.
Acetic acid kuj tseem siv tau los ua cov tshuaj analytical reagents, organic synthesis, synthesis of pigments thiab pharmaceuticals.
Kev siv glacial acetic acid hauv kev lag luam zaub mov:
Hauv kev lag luam khoom noj khoom haus, acetic acid yog siv los ua acidulant, tsw enhancer thiab flavoring tus neeg sawv cev los ua hluavtaws vinegar, ntxiv ntau yam flavoring agents, qhov tsw zoo ib yam li cawv, lub sij hawm raug luv luv, thiab tus nqi pheej yig.Raws li tus neeg sawv cev qaub, nws tuaj yeem siv rau hauv cov khoom sib xyaw ua ke, hauv kev npaj cov kua txiv hmab txiv ntoo, cov khoom noj hauv kaus poom, jelly thiab cheese, thiab siv rau hauv kev sib tw raws li kev xav tau ntau lawm.Nws kuj tseem siv tau los ua ib qho tshuaj tsw qab rau kev sau cawv.
Glacial acetic acid muaj cov khoom txaus ntshai: nws tuaj yeem hnov mob hnyav nrog oxidants, thiab hnov mob hnyav nrog sodium hydroxide thiab potassium hydroxide.Corrosive rau hlau thaum diluted.
Acetic acid nyob rau hauv ntau dua yog corrosive thiab yuav ua rau kub hnyiab rau ntawm daim tawv nqaij, mus tas li qhov muag tsis pom kev, thiab o ntawm mucous daim nyias nyias, yuav tsum tau kev tiv thaiv kom raug.
Glacial Acetic Acid Electrostatic Action: Tej zaum muaj kev phom sij polymerization.
