Mawu Oyamba

m-Nitrobenzenesulfonyl chloride ndi organic compound yomwe mankhwala ake ndi C6H4ClNO4S. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha m-nitrobenzene sulfonyl chloride:

 

Chilengedwe:

m-Nitrobenzenesulfonyl chloride ndi kristalo wachikasu wokhala ndi fungo loyipa. Ndiwokhazikika kutentha kwa firiji, koma kuwola kumachitika pakatenthedwa. Pawiriyi ndi yoyaka komanso yosasungunuka m'madzi, koma imatha kusungunuka mu zosungunulira za organic.

 

Gwiritsani ntchito:

m-Nitrobenzenesulfonyl chloride ndi yofunika kwambiri pakati pa kaphatikizidwe ka organic. Amagwiritsidwa ntchito kwambiri popanga zinthu zachilengedwe monga mankhwala, utoto ndi mankhwala ophera tizilombo. Kuphatikiza apo, itha kugwiritsidwanso ntchito ngati chlorination reagent, reagent yochotsa thiols, komanso chinthu chofunikira pakuwunika mankhwala.

 

Njira:

m-Nitrobenzenesulfonyl kloride akhoza kukonzedwa ndi ayodini mmene p-nitrobenzenesulfonyl kolorayidi. Njira yeniyeni ndikusungunula nitrophenylthionyl chloride mu chloroform, kenaka yikani sodium iodide ndi ayodini pang'ono wa haidrojeni, ndikutenthetsa zomwe zikuchitika kwa nthawi kuti mupeze m-nitrobenzenesulfonyl chloride.

 

Zambiri Zachitetezo:

m-Nitrobenzenesulfonyl chloride ndi poizoni amene amawononga khungu, maso ndi kupuma. Mukamachita opaleshoni, pewani kukhudzana ndi khungu ndi maso, ndipo onetsetsani kuti opaleshoniyo ikuchitika pamalo abwino mpweya wabwino. Zida zodzitetezera monga magolovesi odzitetezera, magalasi oteteza chitetezo ndi masks oteteza ziyenera kuvala mukamagwiritsa ntchito mankhwalawa. Kuonjezera apo, m-nitrobenzene sulfonyl chloride iyenera kusungidwa bwino, kutali ndi magwero a moto ndi okosijeni, ndi kupewa kukhudzana ndi zoyaka. Zikachitika molakwika kapena mwangozi, funsani kuchipatala mwachangu ndikutenga fomu yotsimikizira chitetezo cha pagululo kupita kuchipatala.
