periodic acid(HIO ₄) yakakosha inorganic yakasimba asidhi ine huwandu hwakasiyana hwekushandisa seoxidant munzvimbo dzakasiyana dzesainzi nemaindasitiri. Ichi chinyorwa chinopa sumo yakadzama kune hunhu hwekomboni iyi yakakosha uye mashandisirwo ayo akakosha munzvimbo dzakasiyana siyana.
Chemical properties ye periodic acid
Periodate ndiyo yakanyanya oxidation state okisijeni-ine asidhi yeiodine (+7 valence), inowanzovapo mumakristasi asina ruvara kana fomu chena yehupfu. Iine zvinotevera zvakakosha maitiro:
Yakasimba oxidizing kugona:Iine mwero wekutapudza mukana unosvika 1.6V, unogona oxidize akasiyana organic uye inorganic compounds.
Kunyungudika kwemvura:Yakanyanya kunyungudika mumvura, ichigadzira mhinduro isina ruvara
Kusagadzikana kwekupisa:inoora kana ichipisa pamusoro pe100 ° C
Acidity:ndeyeasidhi yakasimba, inoparadzaniswa zvachose mumushonga une aqueous
Main application nzvimbo
1. Zvikumbiro muAnalytical Chemistry
(1) Malaprade kuita
Kushandiswa kwakakurumbira kweperiodic acid kuri mukuongororwa kwemakemikari emacarbohydrates. Inogona kunyatso oxidize uye kutyora ari padyo diol zvimiro (senge cis diols mumamorekuru emacarbohydrate) kugadzira anowirirana aldehydes kana ketoni. Iyi mhinduro inoshandiswa zvakanyanya kune:
-Kuongorora kwepolysaccharide chimiro
-Kutsunga kweshuga cheni chimiro mu glycoproteins
-Nucleotide sequence analysis
(2) Kutsunga kwemusanganiswa weorganic
Iyo periodate oxidation nzira inogona kushandiswa kuona:
-Glycerol uye zvinyorwa zvayo zveester
-Alpha amino acid yemukati
-Mamwe phenolic makemikari
2. Zvikumbiro muZvinhu Sayenzi
(1) Indasitiri yemagetsi
-Surface kurapwa kwe semiconductor zvinhu
-Micro etching yeakadhindwa edunhu mabhodhi (PCBs)
-Elektroniki chikamu chekuchenesa
(2) Metal processing
-Surface passivation kurapwa kwesimbi isina tsvina
-Metal pamusoro pekuchenesa uye pretreatment
-Oxidation matanho mune electroplating maitiro
3. Biomedical munda
(1) Histological staining
Iyo periodic acid Schiff (PAS) yekusvibisa nzira inzira yakakosha mukuongororwa kwehutachiona:
-Inoshandiswa kuona mapolysaccharides uye glycoproteins mumatishu
-Kuratidza ye basement membrane, fungal cell wall uye zvimwe zvimiro
-Kubatsira kuongororwa kwemamwe mapundu
(2) Biomolecular markers
-Kuongorora kweprotein glycosylation nzvimbo
-Tsvaga nezveshuga complexes pane cell surface
4. Zvikumbiro mune organic synthesis
Sezvinosarudzika oxidant, inotora chikamu mune akasiyana organic maitiro:
-Cis dihydroxylation ye olefins
-Selective oxidation yezvinwiwa
-Kubvisa maitiro emamwe mapoka ekudzivirira
Kuchengetedza kuchengetedza
Kuchenjerera kunofanira kubhadharwa kana uchishandisa periodic acid:
1. Corrosivity: Kuora kwakasimba kuganda, maziso, uye mucous membranes
2. Oxidation njodzi: Kusangana neorganic matter kunogona kukonzera moto kana kuputika
3. Kuchengeta zvinodiwa: Chengeta kure nechiedza, chakavharwa, uye munzvimbo inotonhorera
4. Dziviriro yako pachako: Panguva yekuedza, magirazi ekudzivirira, magirovhosi, uye zvipfeko zvekudzivirira zvinofanirwa kupfekwa.
Nekufambira mberi kwehunyanzvi hwekuongorora uye kuvandudzwa kwesainzi yemidziyo, minda yekushandisa yeperiodic acid ichiri kuwedzera.
Nanomaterial synthesis: se oxidant inobatanidzwa mukugadzirira kwemamwe nanomaterials
Maitiro matsva ekuongorora: akasanganiswa neazvino anolytical zviridzwa senge mass spectrometry
Green Chemistry: Kugadzira yakawedzera hushamwari maitiro ekudzokorodza uye kushandisazve periodic acid
Periodate, seinoshanda uye yakananga oxidant, inoita basa risingadzokerike munzvimbo dzakasiyana siyana kubva pakutsvagisa kwekutanga kusvika kukugadzirwa kwemaindasitiri.
