Intshayelelo
I-α-Bromo-4-chloroacetophenone yi-organic compound. Nalu ulwazi malunga neempawu zayo, ukusetyenziswa, iindlela zokuvelisa kunye nokhuseleko:
Umgangatho:
1. Ukubonakala: i-α-bromo-4-chloroacetophenone iqinile emhlophe.
3. I-Solubility: Inyibilika kwii-solvents eziphilayo ezifana ne-ethanol, i-acetone kunye ne-carbon disulfide kwiqondo lokushisa.
Sebenzisa:
I-α-bromo-4-chloroacetophenone ine-reactivity enamandla yeekhemikhali kwaye ingasetyenziselwa njengento ebalulekileyo ephakathi kwi-organic synthesis.
Indlela:
Ukulungiswa kwe-α-bromo-4-chloroacetophenone kunokuqhutywa ngolu hlobo lulandelayo:
I-1-bromo-4-chlorobenzene iphendulwa nge-acetic anhydride phambi kwe-sodium carbonate ukuvelisa i-1-acetoxy-4-bromo-chlorobenzene. Emva koko isabela nge-methyl bromide phambi kwe-solvent ukuvelisa i-α-bromo-4-chloroacetophenone.
Ulwazi ngoKhuseleko:
Kuphephe ukudibana nolusu, kuphephe ukuphefumla umphunga walo, kwaye usebenzise kwindawo enomoya owaneleyo.
Xa ugcina kwaye usebenzisa, gcina kude kwimithombo yomlilo kunye neendawo eziphakamileyo zokushisa ukuphepha ukuveliswa kweegesi ezinokutsha okanye ezinetyhefu.
Xa ulahla inkunkuma, iimfuno zemimiselo yendawo yendawo kufuneka zithotyelwe ukuqinisekisa ukulahlwa okufanelekileyo.
