Qhov sib txawv tseem ceeb ntawm peracetic acid thiab hydrogen peroxide yog tias peracetic acid yog cov organic tov uas tuaj yeem tawm los ntawm acetic acid raws li cov khoom lag luam oxidation, hos hydrogen peroxide yog cov tshuaj inorganic aqueous uas tuaj yeem tsim dej thaum oxidation.
Peracetic acid thiab hydrogen peroxide yog cov tshuaj nquag nquag uas muaj ntau yam tseem ceeb hauv kev lag luam thiab hauv tsev neeg ib yam.
YPeracetic Acid yog dab tsi?
Peracetic acid yog cov organic compound uas muaj cov tshuaj formula CH3CO3H. Nws yog ib qho organic peroxide uas muaj nyob hauv cov kua tsis muaj xim uas muaj cov ntxhiab tsw ntxhiab tsw. Qhov no yog ib tug muaj zog acid uas yuav ua tau heev corrosive. Peracetic acid tseem hu ua peroxyacetic acid. Txawm li cas los xij, nws yog cov kua qaub qis dua piv rau acetic acid.
Daim duab 01: Cov Qauv Tshuaj ntawm Peracetic Acid
Cov kua qaub no tuaj yeem tsim los ntawm kev ua haujlwm ntawm autoxidation ntawm acetaldehyde industrially. Nyob rau hauv cov txheej txheem no, cov kua qaub ua raws li kev kho mob ntawm acetic acid nrog hydrogen peroxide nyob rau hauv lub xub ntiag ntawm ib tug muaj zog acid catalyst. Xwb, peb tuaj yeem tsim cov kua qaub no los ntawm cov tshuaj tiv thaiv ntawm acetyl chloride thiab acetic anhydride, uas yog cov tshuaj tiv thaiv muaj txiaj ntsig hauv kev tsim cov tshuaj peracetic acid uas muaj dej tsawg.
Muaj ntau qhov tseem ceeb ntawm kev siv cov tshuaj peracetic acid, suav nrog kev siv nws ua cov tshuaj tua kab mob rau sab hauv tsev nyuaj, thov tshuaj tua kab mob hauv cov hom phiaj kho mob, pab tau rau epoxidation ntawm ntau yam sib txawv alkenes, thiab lwm yam.
Y Hydrogen Peroxide yog dab tsi?
Hydrogen peroxide yog ib qho inorganic compound uas muaj cov tshuaj formula H2O2. Hauv nws daim ntawv ntshiab, hydrogen peroxide muaj xim xiav daj, thiab nws tshwm sim ua kua ntshiab. Ntxiv mus, cov kua no yog me ntsis viscos dua dej. Qhov tseeb, nws yog qhov yooj yim tshaj plaws peroxide ntawm tag nrho cov tshuaj peroxide.
Daim duab 02: Cov Qauv Tshuaj ntawm Hydrogen Peroxide
Muaj qee qhov kev siv tseem ceeb ntawm hydrogen peroxide; ntawm lawv, cov ntawv thov loj suav nrog siv nws ua oxidizer, tshuaj dawb, thiab tshuaj tua kab mob. Muaj ib qho tsis ruaj khov peroxide ntawm ob lub atoms ntawm cov pa oxygen hauv qhov sib xyaw no; Yog li, lub compound yog heev reactive. Yog li ntawd, nws maj mam decomposes thaum raug rau lub teeb. Tsis tas li ntawd, peb yuav tsum khaws cov tshuaj no nrog lub stabilizer hauv cov kua qaub tsis muaj zog.
Cov molar loj ntawm hydrogen peroxide yog 34.014 g / mol. Hydrogen peroxide muaj ntxhiab tsw me ntsis. Nws cov ntsiab lus melting yog -0.43 ° C, thiab nws qhov kub ntawm 150.2 ° C. Txawm li cas los xij, yog tias peb boil hydrogen peroxide mus rau qhov kub no, xyaum, nws dhau los ua kom tawg thermal decomposition. Tsis tas li ntawd, qhov sib xyaw no yog miscible nrog dej vim nws tuaj yeem tsim hydrogen bonds. Nyob ntawd, nws tsim ib qho eutectic sib tov nrog dej (ib homogenous sib tov uas melts los yog solidifies ntawm ib qho kub). Qhov kev sib xyaw no qhia txog kev nyuaj siab khov kho.
Qhov txawv ntawm Peracetic Acid thiab Hydrogen Peroxide yog dab tsi?
Peracetic acid thiab hydrogen peroxide yog cov khoom sib xyaw ua ke uas muaj ntau yam tseem ceeb hauv kev lag luam thiab tsev neeg. Qhov sib txawv tseem ceeb ntawm peracetic acid thiab hydrogen peroxide yog tias peracetic acid yog cov organic tov uas tuaj yeem tawm los ntawm acetic acid raws li cov khoom ntawm cov txheej txheem oxidation, hos hydrogen peroxide yog cov tshuaj inorganic aqueous uas tuaj yeem tsim dej thaum oxidation.
Cov hauv qab no qhia txog qhov sib txawv ntawm peracetic acid thiab hydrogen peroxide hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Peracetic Acid vs Hydrogen Peroxide
Peracetic acid yog cov organic compound uas muaj cov tshuaj formula CH3CO3H, thaum Hydrogen peroxide yog ib qho inorganic compound uas muaj cov tshuaj formula H2O2. Qhov sib txawv tseem ceeb ntawm peracetic acid thiab hydrogen peroxide yog tias peracetic acid yog cov tshuaj organic uas tuaj yeem tawm los ntawm acetic acid raws li cov khoom lag luam oxidation, hos hydrogen peroxide yog cov tshuaj inorganic aqueous uas tuaj yeem tsim dej thaum oxidation.
