asidhi yenguva nenguva(HIO ₄) iasidhi yakasimba isingasanganisike ine mashandisirwo akasiyana-siyana se oxidant muzvikamu zvakasiyana zvesainzi nemaindasitiri. Chinyorwa chino chichapa sumo yakadzama kune hunhu hwechinhu ichi chakakosha uye mashandisirwo azvo akakosha muzvikamu zvakasiyana-siyana.
Hunhu hwemakemikari e periodic acid
Periodidate ndiyo acid ye iodine ine oxygen yakawanda (+7 valence), inowanzo kuwanikwa mumakristaro asina ruvara kana muchimiro cheupfu chena. Ine hunhu hunotevera:
Kukwanisa kwakasimba kwe oxidizing:Nekukwanisa kudzikisa kusvika ku1.6V, inogona kuoxidation yemakemikari akasiyana-siyana eorganic neasina organic
Kunyunguduka kwemvura:Inonyungudika zvakanyanya mumvura, zvichiita kuti pave nemushonga usina ruvara
Kusagadzikana kwekupisa:inoora kana yapiswa pamusoro pe100°C
Asidhi:ndeye acid yakasimba, inopatsanurwa zvachose mumvura
Nzvimbo huru dzekushandisa
1. Mashandisirwo muAnalytical Chemistry
(1) Maitiro eMalaprade
Kushandiswa kwakakurumbira kwe periodic acid ndiko kuongorora makemikari emacarbohydrate. Inogona kunyanya kuoxidize nekupwanya ma diol ari pedyo (akadai se cis diols muma carbohydrate molecules) kuti igadzire ma aldehydes kana ma ketone anoenderana nawo. Maitiro aya anoshandiswa zvakanyanya kune:
-Kuongororwa kwechimiro chepolysaccharide
-Kuziva chimiro cheshuga cheni muma glycoproteins
-Kuongororwa kweNucleotide sequence
(2) Kuongororwa kwemakemikari emusanganiswa weorganic
Nzira ye periodate oxidation inogona kushandiswa kuona:
-Glycerol uye huwandu hwayo hwe esters
-Kuwanda kweAlpha amino acid
-Mamwe makemikari ephenolic
2. Mashandisirwo muSainzi Yezvinhu
(1) Indasitiri yemagetsi
-Kugadziriswa kwepamusoro kwezvinhu zve semiconductor
-Kucheka mabhodhi edunhu akadhindwa (PCBs) mudiki
-Kuchenesa zvikamu zvemagetsi
(2) Kugadzira simbi
-Kurapa simbi isina ngura pamusoro pepasi
-Kuchenesa pamusoro pesimbi uye kugadziriswa kwepamberi
- Matanho eOxidation mu electroplating process
3. Munda wezvekurapa
(1) Kudhirowa kwemavara emuchadenga
Nzira yekutsvinda ye periodic acid Schiff (PAS) inzira yakakosha yekuongorora chirwere:
-Inoshandiswa pakuona ma polysaccharides nema glycoproteins mumatishu
-Kuratidzwa kwe membrane yepasi, madziro esero refungus nezvimwe zvivakwa
-Kuongororwa kwemamwe mabundu emuviri
(2) Zviratidzo zveBiomolecular
-Kuongororwa kwenzvimbo dzeprotein glycosylation
-Tsvagiridzo pamusoro peshuga dzakaoma pamusoro pemasero
4. Mashandisirwo mukugadzirwa kwezvinhu zvakasikwa
Senzira yekusarudza oxidant, inobatanidzwa mukuita kwakasiyana-siyana kwe organic:
-Kusanganiswa kwemafuta e-olefin muropa
-Kusarudza oxidation yealcohols
-Kubviswa kwemaitiro emamwe mapoka ekudzivirira
Matanho ekuchengetedza
Kuchenjerera kunofanira kubhadharwa pakushandisa periodic acid:
1. Kuora: Kuora kwakasimba paganda, maziso, uye mucous membranes
2. Njodzi yekudonha kweokisijeni: Kusangana nezvinhu zvipenyu kunogona kukonzera moto kana kuputika
3. Zvinodiwa pakuchengeta: Chengeta kure nechiedza, chakavharwa, uye munzvimbo inotonhorera
4. Kudzivirirwa kwemunhu: Munguva yekuedza, magirazi ekudzivirira, magirovhosi, uye mbatya dzekudzivirira zvinofanirwa kupfekwa
Nekufambira mberi kwehunyanzvi hwekuongorora uye kukura kwesainzi yezvinhu, minda yekushandisa ye periodic acid ichiri kuwedzera.
Kugadzirwa kwezvinhu zveNanomaterial: se oxidant inobatanidzwa mukugadzirira zvimwe zvinhu zveNanomaterial
Maitiro matsva ekuongorora: akabatanidzwa nezvishandiso zvemazuva ano zvekuongorora zvakaita semass spectrometry
Green Chemistry: Kugadzira nzira isingakuvadzi nharaunda yekudzokorodza uye kushandisazve periodic acid
Periodate, semushonga unoshanda uye wakanangana nemakemikari, ine basa risingatsivike muzvikamu zvakasiyana-siyana kubva pakutsvagisa kwekutanga kusvika pakugadzirwa kwemaindasitiri.
