Kuwunikanso kugwiritsa ntchito periodic acid

asidi nthawi ndi nthawi(HIO ₄) ndi asidi wamphamvu wosapangidwa ndi zinthu zachilengedwe womwe umagwiritsidwa ntchito m'njira zosiyanasiyana ngati okosijeni m'magawo osiyanasiyana asayansi ndi mafakitale. Nkhaniyi ipereka chiyambi chatsatanetsatane cha makhalidwe a chinthu chapaderachi ndi ntchito zake zofunika m'magawo osiyanasiyana.

Mankhwala a asidi wa periodic
Periodoti ndi asidi ya ayodini (+7 valence) yomwe imakhala ndi mpweya wambiri, nthawi zambiri imapezeka mu makhiristo opanda mtundu kapena ufa woyera. Ili ndi makhalidwe ofunikira awa:

Mphamvu yamphamvu ya oxidizing:Ndi mphamvu yochepetsera yokhazikika mpaka 1.6V, imatha kupangitsa kuti zinthu zosiyanasiyana zachilengedwe komanso zosapangidwa zikhale zosakanikirana.

Kusungunuka kwa madzi:Amasungunuka kwambiri m'madzi, kupanga yankho lopanda utoto

Kusakhazikika kwa kutentha:zimawola zikatenthedwa pamwamba pa 100 ° C

Asidi:ndi ya asidi wamphamvu, imagawanika kwathunthu mu yankho lamadzi

Madera akuluakulu ogwiritsira ntchito
1. Kugwiritsa Ntchito mu Analytical Chemistry
(1) Kachitidwe ka Malaprade
Kugwiritsa ntchito kwambiri periodic acid ndiko kusanthula mankhwala a chakudya. Imatha kusakaniza ndikuswa kapangidwe ka diol komwe kali pafupi (monga cis diols mu mamolekyulu a chakudya) kuti ipange aldehydes kapena ketones ofanana. Izi zimagwiritsidwa ntchito kwambiri pa:
-Kusanthula kapangidwe ka polysaccharide
-Kudziwa kapangidwe ka unyolo wa shuga mu ma glycoprotein
-Kusanthula kwa ndondomeko ya nucleotide

(2) Kuzindikira zinthu zachilengedwe zomwe zimapangidwa ndi zinthu zachilengedwe
Njira ya periodate oxidation ingagwiritsidwe ntchito kudziwa:
-Glycerol ndi kuchuluka kwa ma esters ake
- Kuchuluka kwa amino acid mu alpha
-Ma phenolic compound ena

2. Kugwiritsa Ntchito mu Sayansi ya Zipangizo
(1) Makampani a zamagetsi
-Kuchiza pamwamba pa zinthu za semiconductor
-Kujambula pang'ono kwa ma board osindikizidwa (ma PCB)
-Kuyeretsa zinthu zamagetsi
(2) Kukonza zitsulo
-Kuchiza chitsulo chosapanga dzimbiri kuti chisawonongeke pamwamba
-Kuyeretsa pamwamba pa zitsulo ndi kukonzekera
- Njira zoyeretsera ma oxygenation mu electroplating

3. Gawo la zamankhwala
(1) Kupaka utoto wa histological
Njira yopaka utoto wa periodic acid Schiff (PAS) ndi njira yofunika kwambiri pozindikira matenda:
- Amagwiritsidwa ntchito pozindikira ma polysaccharides ndi ma glycoprotein m'maselo.
- Kuwonetsa nembanemba ya pansi, khoma la maselo a bowa ndi zina zomwe zili mkati mwake
-Kuzindikira matenda enaake a zotupa

(2) Zizindikiro za biomolecular
-Kusanthula malo a glycosylation ya mapuloteni
-Kafukufuku wa zinthu zosakaniza shuga pamwamba pa maselo

4. Kugwiritsa ntchito popanga zinthu zachilengedwe
Monga chowonjezera chosankha, chimagwira ntchito zosiyanasiyana zachilengedwe:
-Kuchuluka kwa ma olefini mu cis dihydroxylation
-Kusankha okosijeni wa mowa
-Kuchotsa zochita za magulu ena oteteza

Zodzitetezera

Samalani kwambiri mukamagwiritsa ntchito periodic acid:
1. Kuwononga: Kuwononga kwambiri khungu, maso, ndi nembanemba ya mucous
2. Kuopsa kwa okosijeni: Kukhudzana ndi zinthu zachilengedwe kungayambitse moto kapena kuphulika
3. Zofunikira pakusunga: Sungani kutali ndi kuwala, kotsekedwa, komanso pamalo ozizira
4. Chitetezo chaumwini: Pa nthawi yoyeserera, magalasi oteteza, magolovesi, ndi zovala zoteteza ziyenera kuvalidwa

Ndi kupita patsogolo kwa njira zowunikira komanso chitukuko cha sayansi ya zinthu, magawo ogwiritsira ntchito a periodic acid akukulirakulirabe.
Kupanga zinthu zina za nanomaterial: monga okosijeni yomwe imagwira ntchito yokonzekera zinthu zina za nanomaterial
Njira zatsopano zowunikira: kuphatikiza ndi zida zamakono zowunikira monga mass spectrometry
Chemistry Yobiriwira: Kupanga njira yosamalira chilengedwe yobwezeretsanso ndikugwiritsanso ntchito asidi nthawi ndi nthawi

Periodate, monga oxidant yothandiza komanso yeniyeni, imagwira ntchito yofunika kwambiri m'magawo osiyanasiyana kuyambira kafukufuku woyambira mpaka kupanga mafakitale.
