He totoka mā te konutai iodide i puta mai i te tauhohenga i waenga i te konutai kāponāte me te waikawa hauwaioraiti me te mimiti haere o te wairewa. Kei reira ngā matū waikore, ngā matū dihydrate me ngā matū pentahydrate. Koinei te rauemi mata mō te hanga i te iodine, hei whakamahi i roto i te rongoā me te whakaahua. Ko te wairewa waikawa o te konutai iodide, nā te whakaputanga o te waikawa hauwaioraiti, e whakaatu ana i te kaha whakaheke.
Ngā Āhuatanga Hua
He tioata poraka kore tae, he paura tioata mā rānei te konutai iodide. Kāore he kakara, he tote te reka, he kawa. Ka mimiti i te makuku mai i te hau; ka huri parauri mārire ina pāngia e te hau nā te mea kua puta te iodine; ko te mātotorutanga he 3.67g/cm3; ka rewa i te 660°C; ka mimiti i te 1,304°C; ko te pēhanga kohu he 1 torr i te 767°C me te 5 torr i te 857°C; he tino wairewa i roto i te wai, 178.7 g/100 mL i te 20°C me te 294 g/100 mL i te 70°C; ka wairewa i roto i te etanoru me te acetone.
Tono
He whānuitia te whakamahinga o te konutai iodide mō te whakawhiti halide (te tauhohenga Finkelstein), hei tauira, i roto i te huringa o te alkyl chloride, te allyl chloride me te arylmethyl chloride ki roto i ō rātou iodide, he matū matua mō ngā hua rongoā me ngā hua matū pai. Ka whakamahia ēnei hei whakapai ake i te whai huatanga o te hanganga o ngā tāpiringa Wittig mai i ngā chloride me ngā bromides iti ake te tauhohenga. Ka whakamahia ngā whakaritenga tika hei tāpiringa matūkai. Ka whakamahia te konutai iodide hei matū matua mō te kaiwhakahaere i roto i te polymerization emulsion ab initio. Ka whakamahia te konutai iodide i roto i te whakatau i te hāora rewa i roto i te tikanga Winkler whakarerekētia, te hanganga o te fluorescent dye coppersensor-1 (CS1) mō te whakaahua i ngā puna parahi koretake i roto i ngā tauira koiora, me te wehenga o ngā esters, lactones, carbamates me ngā ethers i roto i te whakakotahitanga me te chlorotrimethylsilane.
Ka taea te whakamahi mō te cystography, te retrograde urography, te cholangiography mā te ngongo-T me te angiography fistula o ētahi atu wāhanga.
Urography: 6.25% 100ml. Cystography: 6.25% 150ml. Retrograde pyelography: 12.5% 5~7ml. T-tube cholangiography: 12.5% 10~30ml. Fistula angiography: whakatau i te wāhi werohanga me te horopeta i runga i te āhua o te mate.
I whakamahia te konutai iodide hei wāhanga i roto i te whakarite i te otinga tae hematoxylin a Mayer.
Ka taea te whakamahi i roto i ngā tukanga e whai ake nei:
Te matū whakataki i roto i te whakapūhuitanga o te butyl acrylate.
Kaihoko Chaotropic i roto i te tangohanga o te DNA.
He kaiāwhina tango-tiaki i roto i te tango i te rōpū N-tert-butyloxycarbonyl i roto i ngā waikawa amino.
Kaiwhakaora tinei mura wairewa-wai.
Te Tākai me te Rokiroki
Tākai: Pahu kātene kua whakakikoruatia ki te putea kirihou, 25KG/pahu.
Rokiroki: Kua hiritia, ā, kua rongoatia ki te pōuri.
