Isingeniso

I-Diiodomethane. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-dioodomethane:

 

Ikhwalithi:

Ukubukeka: I-Diiodomethane iwuketshezi olungenambala ukuya kokuphuzi olukhanyayo olunephunga elikhethekile.

Ukuminyana: Ukuminyana kuphezulu, cishe ku-3.33 g/cm³.

Ukunyibilika: kuncibilika kuzincibilikisi eziphilayo ezifana notshwala nama-ether, okungancibiliki emanzini.

Ukuzinza: Izinzile uma iqhathaniswa, kodwa ingase iboliswe ukushisa.

 

Sebenzisa:

Ucwaningo lwamakhemikhali: I-Diiodomethane ingasetshenziswa njenge-reagent elabhorethri yokusabela kwe-organic synthesis kanye nokulungiswa kwama-catalysts.

Isibulala-magciwane: I-Diiodomethane inezindawo ezibulala amagciwane futhi ingasetshenziswa njengesibulala-magciwane ezimeni ezithile ezithile.

 

Indlela:

I-Diiodomethane ingalungiswa ngokujwayelekile:

Ukusabela kwe-methyl iodide nge-iodide yethusi: I-Methyl iodide isabela nge-iodide yethusi ukukhiqiza i-dioodomethane.

Ukusabela kwe-methanol ne-iodine: i-methanol isabela nge-iodine, futhi i-methyl iodide ekhiqiziwe isabela nge-iodide yethusi ukuze kutholakale i-dioodomethane.

 

Ulwazi Lokuphepha:

Ubuthi: I-Diiodomethane iyacasula futhi ilimaza isikhumba, amehlo, nesistimu yokuphefumula, futhi ingaba nemiphumela ohlelweni lwezinzwa oluphakathi.

Izinyathelo zokuzivikela: Gqoka izingilazi zokuzivikela, amagilavu ​​kanye namamaski egesi uma usebenzisa ukuze uqinisekise indawo yaselabhorethri enomoya omuhle.

Isitoreji Nokuphatha: Gcina endaweni evalekile, epholile, enomoya omuhle, kude nomlilo nama-oxidants. Uketshezi olungcolile kufanele kulahlwe ngokuhambisana nemithetho efanele yezemvelo.
