Mawu Oyamba
Propilate bromide ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha propionyl bromide:
Ubwino:
1. Maonekedwe ndi katundu: Propionyl bromide ndi madzi opanda mtundu omwe ali ndi fungo lopweteka lapadera.
2. Kusungunuka: Propionyl bromide imasungunuka mu zosungunulira za organic, monga ether ndi benzene, komanso osasungunuka m'madzi.
3. Kukhazikika: Propionyl bromide ndi yosakhazikika ndipo imapangidwa mosavuta ndi madzi kuti ipange acetone ndi hydrogen bromide.
Gwiritsani ntchito:
1. Organic synthesis: Propionyl bromide ndi yofunika organic synthesis reagent yomwe ingagwiritsidwe ntchito poyambitsa magulu a propionyl kapena maatomu a bromine.
2. Ntchito zina: propionyl bromide ingagwiritsidwenso ntchito pokonzekera zotumphukira za acyl bromide, zothandizira kupanga kaphatikizidwe ka organic ndi zapakati mu chemistry yokoma.
Njira:
Kukonzekera kwa propionyl bromide kumatha kupezeka ndi momwe acetone ndi bromine. Zomwe zimachitika zimatha kuchitika kutentha kapena kutentha.
Zambiri Zachitetezo:
1. Propionyl bromide imakwiyitsa kwambiri ndipo ingayambitse kupsa mtima pakhungu ndi maso, choncho chisamaliro chiyenera kutengedwa kuti musagwirizane.
2. Propionyl bromide imakhudzidwa ndi chinyezi cha hydrolysis ndipo iyenera kusungidwa pamalo ozizira, owuma ndi otsekedwa mwamphamvu.
3. Mpweya wabwino wa mpweya uyenera kusungidwa pakagwiritsidwe ntchito kuti usapume mpweya wake.
4. Yang'anirani njira zodzitetezera panthawi yosungira, mayendedwe ndi kagwiridwe, monga kuvala magolovesi oteteza, magalasi ndi zovala zoteteza.
