Mawu Oyamba

Diiodomethane. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha diodomethane:

 

Ubwino:

Maonekedwe: Diiodomethane ndi madzi achikasu opepuka opanda utoto komanso fungo lapadera.

Kachulukidwe: Kuchulukana kwake ndikwambiri, pafupifupi 3.33 g/cm³.

Kusungunuka: Kusungunuka mu zosungunulira organic monga ma alcohols ndi ether, osasungunuka m'madzi.

Kukhazikika: Kukhazikika, koma kumatha kuwola ndi kutentha.

 

Gwiritsani ntchito:

Kafukufuku wamankhwala: Diiodomethane itha kugwiritsidwa ntchito ngati reagent mu labotale ya organic synthesis reaction ndikukonzekera zothandizira.

Mankhwala ophera tizilombo toyambitsa matenda: Diiodomethane ili ndi mankhwala ophera mabakiteriya ndipo imatha kugwiritsidwa ntchito ngati mankhwala ophera tizilombo nthawi zina.

 

Njira:

Diiodomethane ikhoza kukonzedwa motere:

Kuchita kwa methyl iodide ndi iodide yamkuwa: Methyl iodide imapangidwa ndi iodide yamkuwa kuti ipange diiodomethane.

Methanol ndi ayodini: methanol imayendetsedwa ndi ayodini, ndipo methyl iodide yopangidwa imayendetsedwa ndi iodide yamkuwa kuti ipeze diiodomethane.

 

Zambiri Zachitetezo:

Poizoni: Diiodomethane imakwiyitsa komanso kuwononga khungu, maso, ndi kupuma, ndipo imatha kukhala ndi zotsatirapo pakatikati pa mitsempha.

Njira zodzitetezera: Valani magalasi odzitchinjiriza, magulovu ndi masks oteteza gasi mukamagwiritsa ntchito kuonetsetsa kuti malo a labotale azikhala ndi mpweya wabwino.

Kasungidwe ndi Kagwiridwe: Sungani pamalo osindikizidwa, ozizira, opanda mpweya wabwino, kutali ndi moto ndi zotulutsa mpweya. Zakumwa zonyansa ziyenera kutayidwa motsatira malamulo okhudzana ndi chilengedwe.
