Solubility: yosavuta kudya mumpweya wonyowa.Mukayatsidwa ndi kuwala ndi mpweya, ayodini waulere amatha kupatulidwa ndikusanduka chikasu, zomwe zimakhala zosavuta kutembenukira zachikasu mu njira ya acidic amadzimadzi.Imasungunuka mosavuta m'madzi ndipo imatenga kutentha kwambiri ikasungunuka.Imasungunuka mu ethanol, acetone, methanol, glycerol ndi liquid hydrogen, komanso sungunuka pang'ono mu ether.
Ntchito ndi kugwiritsa ntchito:
1. ikayatsidwa ndi kuwala kapena ikayikidwa mumlengalenga kwa nthawi yayitali, imatha kutulutsa ayodini waulere ndikutembenukira chikasu.Ndikosavuta kuti oxidize ndi kutembenukira chikasu mu acidic amadzimadzi njira.
2. imasanduka yachikasu mosavuta mu njira ya acidic amadzimadzi.Potaziyamu iodide ndi cosolvent ya ayodini.Akasungunuka, amapanga potaziyamu triiodide ndi ayodini, ndipo atatuwo amakhala ofanana.
3. potaziyamu iodide ndi chakudya chololedwa cha ayodini, chomwe chingagwiritsidwe ntchito mu chakudya cha makanda malinga ndi malamulo a ku China.Mlingo ndi 0.3-0.6mg/kg.Itha kugwiritsidwanso ntchito ngati mchere wamchere.Mlingo wa mankhwalawa ndi 30-70 ml / kg.Monga gawo la thyroxine, ayodini amatenga nawo gawo mu metabolism yazinthu zonse za ziweto ndi nkhuku ndikusunga kutentha kwamkati.Ndi hormone yofunikira pakukula ndi kubereka kwa ziweto ndi nkhuku.Ikhoza kupititsa patsogolo kukula kwa ziweto ndi nkhuku ndikulimbikitsa thanzi la thupi.Ngati thupi la ziweto ndi nkhuku akusowa ayodini, zingachititse kuti kagayidwe kachakudya matenda, matenda thupi, goiter, zimakhudza mitsempha, khungu khungu ndi chakudya chimbudzi ndi mayamwidwe, ndipo pamapeto pake kumabweretsa kukula pang'onopang'ono ndi chitukuko.
Imasungunuka mosavuta m'madzi ndipo imatenga kutentha ikasungunuka.Kusungunuka m'madzi 100g ndi 127.5g (0 ℃), 144g (20 ℃), 208g (100 ℃).Pakakhala mpweya wonyowa ndi carbon dioxide, umawola ndi kusanduka wachikasu.Kusungunuka mu methanol, ethanol ndi glycerol.ayodini amasungunuka mosavuta mu njira yamadzimadzi ya potaziyamu iodide.Imachepetsetsa ndipo imatha kukhala oxidizing ndi ma oxidizing agents monga hypochlorite, nitrite ndi ayodini a ferric kuti amasule ayodini aulere.Imawola ikayatsidwa ndi kuwala, choncho iyenera kusungidwa pamalo osindikizidwa, amdima komanso ozizira.Kuphatikiza pa kugwiritsidwa ntchito kwamankhwala ndi kujambula, kumagwiritsidwanso ntchito ngati chowunikira.
Katundu ndi kukhazikika:
1. potaziyamu iodide nthawi zambiri amagwiritsidwa ntchito ngati dzimbiri inhibitor kwa pickling zitsulo kapena synergist zina dzimbiri inhibitors.Potaziyamu iodide ndiye zinthu zopangira ayodini ndi utoto.Amagwiritsidwa ntchito ngati zithunzi emulsifier, chakudya zowonjezera, expectorant ndi okodzetsa mu mankhwala, mankhwala kupewa ndi kuchiza goiter ndi hyperthyroidism pamaso opaleshoni, ndi kusanthula reagent.Amagwiritsidwa ntchito m'makampani ojambula zithunzi ngati emulsifier ya photosensitive, amagwiritsidwanso ntchito ngati mankhwala ndi zowonjezera zakudya.
2. amagwiritsidwa ntchito ngati chowonjezera cha chakudya.Iodine, monga gawo la thyroxine, imatenga nawo gawo mu metabolism yazinthu zonse za ziweto ndi nkhuku ndikusunga kutentha m'thupi.Iodine ndi mahomoni ofunikira pakukula, kubereka ndi kuyamwitsa kwa ziweto ndi nkhuku.Ikhoza kupititsa patsogolo kukula kwa ziweto ndi nkhuku ndikulimbikitsa thanzi la thupi.Ngati thupi la ziweto ndi nkhuku akusowa ayodini, zingachititse kuti kagayidwe kachakudya matenda, matenda a thupi, goiter, zimakhudza mitsempha ntchito, chimbudzi ndi mayamwidwe odula mtundu ndi chakudya, ndipo potsirizira pake kumabweretsa kukula pang'onopang'ono ndi chitukuko.
3. makampani azakudya amachigwiritsa ntchito ngati chowonjezera cha zakudya (zowonjezera ayodini).Itha kugwiritsidwanso ntchito ngati chowonjezera cha chakudya.
4. ntchito monga kusanthula reagent, monga kukonzekera ayodini muyezo njira monga wothandiza reagent.Amagwiritsidwanso ntchito ngati photosensitive emulsifier ndi zowonjezera chakudya.Amagwiritsidwa ntchito m'makampani opanga mankhwala.
5. ayodini wa potaziyamu ndi cosolvent ya ayodini ndi ayodini ena osasungunuka achitsulo.
6. Iodide ya potaziyamu imakhala ndi ntchito ziwiri zazikulu pochiritsa pamwamba: choyamba, imagwiritsidwa ntchito posanthula mankhwala.Amagwiritsa ntchito reducibility yapakatikati ya ayodini ndi ayodini ena oxidizing kuti achite kuti apange ayodini wosavuta, ndiyeno amawerengera kuchuluka kwa zinthu zomwe zayesedwa mwa kutsimikiza kwa ayodini;Chachiwiri, amagwiritsidwa ntchito popanga ma ion zitsulo.Kugwiritsiridwa ntchito kwake kumakhala ngati chothandizira chopangira cuprous ndi siliva mu electroplating copper silver alloy.
Njira yopangira:
1. pakali pano, njira yochepetsera asidi ya formic imagwiritsidwa ntchito kwambiri popanga ayodini wa potaziyamu ku China.Ndiko kuti, iodide ya potaziyamu ndi iodate ya potaziyamu amapangidwa ndi kuyanjana kwa ayodini ndi potaziyamu hydroxide, ndiyeno iodate ya potaziyamu imachepetsedwa ndi formic acid kapena makala.Komabe, iodate imapangidwa mwanjira iyi, kotero mankhwalawa sayenera kugwiritsidwa ntchito ngati chowonjezera cha chakudya.Zakudya za potaziyamu iodide zimatha kupangidwa ndi njira yachitsulo.
Njira yosungira:
1. Idzasungidwa m'nyumba yosungiramo yozizirira, mpweya wabwino komanso wamdima.Idzatetezedwa ku mvula ndi dzuwa panthawi yoyendetsa.
2. chogwiriracho mosamala pakukweza ndi kutsitsa.Kugwedezeka ndi kukhudza ndizoletsedwa.Pakakhala moto, mchenga ndi carbon dioxide zozimitsa moto zingagwiritsidwe ntchito.
