Acetic acid, cov kua tsis muaj xim, muaj cov ntxhiab tsw muaj zog.Lub melting point ntawm acetic acid yog 16.6 ℃, lub boiling point yog 117.9 ℃, tus txheeb ze ceev yog 1.0492 (20/4 ℃), thiab lub refractive index yog 1.3716.Pure acetic acid tuaj yeem tsim cov dej khov zoo li hauv qab 16.6 ° C, yog li nws feem ntau hu ua glacial acetic acid.Acetic acid yog ib qho tseem ceeb organic chemical raw khoom, feem ntau yog siv los npaj vinyl acetate monomer (VAM), cellulose acetate, acetic anhydride, terephthalic acid, chloroacetic acid, polyvinyl cawv, acetate thiab hlau acetate.
Acetic acid yog dav siv nyob rau hauv cov organic synthesis, tshuaj, tshuaj tua kab, luam ntawv thiab dyeing, textiles, zaub mov, xim, adhesives thiab ntau lwm yam lag luam.Acetic acid yog ib qho tseem ceeb ntawm cov khoom siv raw khoom.Kev tsim cov thev naus laus zis ntawm acetic acid feem ntau suav nrog: txoj kev methanol carbonylation, acetaldehyde oxidation, ethylene ncaj oxidation thiab lub teeb roj oxidation.Ntawm lawv, methanol carbonylation yog cov cuab yeej siv dav tshaj plaws, suav txog ntau dua 60% ntawm tag nrho cov peev txheej tsim khoom thoob ntiaj teb, thiab cov qauv no tseem loj hlob.
Lub peev xwm tsim cov acetic acid thoob ntiaj teb tau qhia txog kev nce siab, thiab nws qhov kev thov thoob ntiaj teb tseem yuav loj hlob ntawm qhov nruab nrab txhua xyoo ntawm kwv yees li 5% hauv ob peb xyoos tom ntej no, ntawm 94% ntawm lub ntiaj teb tshiab acetic acid muaj peev xwm yuav tshwm sim hauv Asia, thiab thaj av Esxias kuj yuav nyob rau yav tom ntej.Ua tus loj hlob sai ntawm kev lag luam thoob ntiaj teb xav tau hauv tsib xyoos.
daim ntawv thov:
