Mawu Oyamba
4,4'-Dichlorobenzophenone ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
1. Maonekedwe: 4,4′-Dichlorobenzophenone ndi yopanda mtundu mpaka kuwala kwachikasu kolimba kolimba.
3. Kusungunuka: Zimasungunuka mu zosungunulira zina monga ethers ndi alcohols, koma sizisungunuka m'madzi.
Gwiritsani ntchito:
1. Chemical reagents: 4,4'-dichlorobenzophenone chimagwiritsidwa ntchito ngati reagent mu kaphatikizidwe organic, makamaka zimachitikira mu kaphatikizidwe onunkhira mankhwala.
2. Mankhwala ophera tizilombo: Atha kugwiritsidwanso ntchito ngati njira yapakatikati popanga mankhwala ena ophera tizilombo.
Njira:
Kukonzekera kwa 4,4′-dichlorobenzophenone nthawi zambiri kumachitika motere:
1. Benzophenone imakhudzidwa ndi thionyl chloride pamaso pa n-butyl acetate kuti ipereke 2,2′-diphenylketone.
Kenako, 2,2′-diphenyl ketone imakhudzidwa ndi thionyl chloride pamaso pa sulfuric acid kupanga 4,4′-dichlorobenzophenone.
Zambiri Zachitetezo:
1. 4,4′-Dichlorobenzophenone ayenera kutenga njira zotetezera zofunika pakugwira ndi kusunga kuti asagwirizane ndi khungu, maso ndi pakamwa.
2. Valani magolovesi oteteza, magalasi ndi masks mukamagwiritsa ntchito.
3. Gwirani ntchito pamalo olowera mpweya wabwino ndipo pewani kutulutsa nthunzi yake.
4. Mukakhudza mwangozi kapena kumwa, funsani kuchipatala mwamsanga ndipo mubweretse chizindikiro kapena pepala lachitetezo cha chinthucho.
