Solubility: nyore kuita deliquesce mumhepo yakanyorova.Kana yaiswa kuchiedza nemhepo, ayodhini yemahara inogona kupatsanurwa kunze uye kushanduka yero, zviri nyore kuita yero mune acidic aqueous solution.Inonyungudika nyore nyore mumvura uye inotora kupisa zvakanyanya kana yanyungudika.Inonyungudika mu ethanol, acetone, methanol, glycerol uye liquid hydrogen, uye inonyungudika zvishoma muether.
Basa uye kushandiswa:
1. kana yakavhenekerwa nechiedza kana kuiswa mumhepo kwenguva yakareba, inogona kudonhedza iodine yemahara uye kuita yero.Zviri nyore kuita oxidize uye kushandura yero mune acidic aqueous solution.
2. inoshanduka yero zviri nyore muacidic aqueous solution.Potassium iodide ndiyo cosolvent yeiodine.Kana yanyungudutswa, inoumba potassium triiodide ine iodine, uye iyo mitatu iri mukuenzanisa.
3. potassium iodide inobvumirwa kudya iodine fortifier, inogona kushandiswa mukudya kwevacheche maererano nemitemo yeChina.Muyero ndeye 0.3-0.6mg/kg.Inogonawo kushandiswa patafura yemunyu.Muyero ndeye 30-70ml/kg.Sechikamu che thyroxine, iodine inotora chikamu mumetabolism yezvinhu zvese muzvipfuyo nehuku uye inochengetedza chiyero chemukati chekupisa.Ihomoni yakakosha pakukura nekubereka kwezvipfuyo nehuku.Inogona kuvandudza kukura kwekuita kwezvipfuyo nehuku uye kukurudzira hutano hwemuviri.Kana muviri wezvipfuyo nehuku ukashomeka mu iodine, zvinokonzeresa kukanganiswa kwemetabolism, kusagadzikana kwemuviri, goiter, kukanganisa mashandiro etsinga, ruvara rweganda uye kugaya kwekudya uye kunyura, uye pakupedzisira zvinotungamira mukunonoka kukura nekukura.
Inonyungudika nyore nyore mumvura uye inotora kupisa kana yanyungudutswa.Kunyungudika mumvura 100g i127.5g (0 ℃), 144g (20 ℃), 208g (100 ℃).Kana kune mhepo yakanyorova uye kabhoni dhaikisaidhi, inowora uye kushanduka yero.Soluble mu methanol, ethanol uye glycerol.Iodine inonyungudika zviri nyore mune aqueous solution ye potassium iodide.Inoderedza uye inogona kuve yakasvibiswa neoxidizing agents se hypochlorite, nitrite uye ferric ions kuti isunungure iodine yemahara.Inoora kana yaiswa pachiedza, saka inofanira kuchengetwa munzvimbo yakavharwa, ine rima uye inotonhorera.Pamusoro pekushandiswa kwemishonga uye kutora mifananidzo, inoshandiswawo seanalytical reagent.
Properties uye kugadzikana:
1. potassium iodide inowanzoshandiswa se corrosion inhibitor yesimbi pickling kana synergist yeimwe corrosion inhibitors.Potassium iodide ndiyo mbishi yekugadzira iodide nedhayi.Inoshandiswa semufananidzo emulsifier, chikafu chinowedzera, expectorant uye diuretic mumishonga, mushonga wekudzivirira uye kurapwa kwegoiter uye hyperthyroidism isati yaitwa, uye analytical reagent.Inoshandiswa muindasitiri yemifananidzo se photosensitive emulsifier, inoshandiswawo semushonga uye zvekuwedzera zvekudya.
2. inoshandiswa sekuwedzera kwekudya.Iodine, sechikamu che thyroxine, inotora chikamu mumetabolism yezvinhu zvese muzvipfuwo nehuku uye inochengetedza chiyero chekupisa mumuviri.Iodine ihomoni yakakosha pakukura, kubereka uye kuyamwisa kwezvipfuyo nehuku.Inogona kuvandudza kukura kwekuita kwezvipfuyo nehuku uye kukurudzira hutano hwemuviri.Kana muviri wezvipfuyo nehuku ukashomeka mu iodine, zvinokonzeresa kusagadzikana kwemetabolism, kusagadzikana kwemuviri, goiter, kukanganisa mashandiro etsinga, kugaya uye kutorwa kwejasi ruvara uye chikafu, uye pakupedzisira kutungamirira kunonoka kukura uye kukura.
3. indasitiri yezvekudya inoishandisa sekuwedzera kwekudya (iodine fortifier).Inogonawo kushandiswa sekuwedzera kwekudya.
4. inoshandiswa seanalytical reagent, sekugadzirira iyo iodine yakajairwa mhinduro seyekubatsira reagent.Inoshandiswawo se photosensitive emulsifier uye yekuwedzera feed.Inoshandiswa muindasitiri yemishonga.
5. potassium iodide ndiyo cosolvent yeiodine uye mamwe iodides esimbi isinganyunguriki.
6. potassium iodide ine mashandisirwo makuru maviri mukurapa kwepamusoro: kutanga, inoshandiswa pakuongorora makemikari.Inoshandisa iyo yepakati reducibility yeiodine ion uye mamwe maoxidizing ions kuita kuti ibudise iyo iodine iri nyore, uyezve inoverengera kusangana kwechinhu chakaedzwa kuburikidza nekugadzwa kweiodine;Chechipiri, inoshandiswa kugadzirisa mamwe maion simbi.Kushandiswa kwayo kwakajairwa sechinhu chinoomesera che cuprous uye sirivheri mu electroplating mhangura sirivheri alloy.
Synthetic nzira:
1. pari zvino, nzira yekuderedza yefomic acid inonyanya kushandiswa kugadzira potassium iodide muChina.Iko ndiko kuti, iodide ye potassium uye iodate ye potassium inobudiswa nekubatana kweiodine uye potassium hydroxide, uye ipapo potassium iodate inoderedzwa nefomic acid kana marasha.Zvisinei, iodate inogadzirwa nenzira iyi, saka chigadzirwa hachifaniri kushandiswa sechikafu chekuwedzera.Chikafu giredhi potassium iodide inogona kugadzirwa nesimbi filings nzira.
Nzira yekuchengetedza:
1. ichachengetwa munzvimbo inotonhorera, ine mhepo uye ine rima.Ichadzivirirwa kubva kumvura nezuva panguva yekufambisa.
2. kubata nekungwarira panguva yekurodha nekuburitsa.Vibration uye kukanganisa zvinorambidzwa zvachose.Kana pane moto, jecha uye carbon dioxide fire extinguisher zvinogona kushandiswa.
