Mawu Oyamba
3,4 '-Dichloropropiophenone, mankhwala formula C9H7Cl2O, ndi pawiri organic.
Chilengedwe:
3,4 '-Dichloropropiophenone ndi cholimba chopanda mtundu mpaka chotumbululuka chokhala ndi fungo lamankhwala lodziwika bwino. Sisungunuka m'madzi ndipo imasungunuka pang'ono mu ma alcohols ndi ethers.
Gwiritsani ntchito:
3,4 '-Dichloropropiophenone nthawi zambiri amagwiritsidwa ntchito ngati reagent mu organic synthesis. Itha kugwiritsidwa ntchito popanga mankhwala, utoto ndi zinthu zina. Itha kugwiritsidwanso ntchito ngati zopangira zopangira mankhwala ophera tizilombo komanso zokometsera.
Njira Yokonzekera:
Pali njira zosiyanasiyana zokonzekera 3,4 '-Dichloropropiophenone. Njira yodziwika bwino ndiyo kupeza 3,4′-dichlorophenyl ethanone ndi bromination kapena chlorination pansi pa zinthu zamchere.
Zambiri Zachitetezo:
3,4 '-Dichloropropiophenone ndi poizoni ndipo kukhudzana mwachindunji ndi khungu ndi inhalation ya nthunzi yake ayenera kupewa. Zida zodzitetezera zoyenerera, monga magolovesi oteteza maso ndi maso, ziyenera kuvalidwa pozigwiritsa ntchito kapena pozigwira. Pewani kutentha kwambiri ndikutsegula moto panthawi yosungira. Onetsetsani kuti mwaigwiritsa ntchito pamalo abwino komanso opanda mpweya wabwino ndikutaya mumtsuko wopanda vuto lililonse. Ngati kuyamwa kapena kukhudzana kumachitika, pitani kuchipatala mwamsanga.
