Taw qhia
4,4′-Dichlorobenzophenone yog cov organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
1. Cov tsos mob: 4,4′-Dichlorobenzophenone yog xim tsis muaj xim rau lub teeb daj crystalline khoom.
3. Solubility: Nws yog soluble hauv qee cov organic solvents, xws li ethers thiab cawv, tab sis nws yog insoluble hauv dej.
Siv:
1. Tshuaj reagents: 4,4′-dichlorobenzophenone yog dav siv raws li ib tug reagent nyob rau hauv cov organic synthesis, tshwj xeeb tshaj yog rau cov tshuaj tiv thaiv nyob rau hauv lub synthesis ntawm aromatic compounds.
2. Cov tshuaj tua kab nruab nrab: Nws kuj tuaj yeem siv los ua ib qho nruab nrab hauv kev sib xyaw ntawm qee cov tshuaj tua kab.
Txoj kev:
Kev npaj ntawm 4,4'-dichlorobenzophenone feem ntau yog ua los ntawm cov kauj ruam hauv qab no:
1. Benzophenone reacts nrog thionyl chloride nyob rau hauv lub xub ntiag ntawm n-butyl acetate muab 2,2′-diphenylketone.
Tom ntej no, 2,2′-diphenyl ketone reacts nrog thionyl chloride nyob rau hauv lub xub ntiag ntawm sulfuric acid rau daim ntawv 4,4′-dichlorobenzophenone.
Cov ntaub ntawv kev nyab xeeb:
1. 4,4′-Dichlorobenzophenone yuav tsum ua raws li qhov tsim nyog ntsuas kev nyab xeeb thaum tuav thiab khaws cia kom tsis txhob sib cuag nrog daim tawv nqaij, qhov muag thiab qhov ncauj.
2. Hnav cov hnab looj tes tiv thaiv, tsom iav thiab qhov ncauj qhov ntswg thaum siv.
3. Ua haujlwm hauv qhov chaw uas muaj cua zoo thiab tsis txhob nqus nws cov vapors.
4. Nyob rau hauv rooj plaub ntawm kev sib chwv los yog kev noj, nrhiav kev kho mob tam sim ntawd thiab nqa ib daim ntawv lo los yog daim ntawv qhia kev nyab xeeb rau cov khoom.
