Intshayelelo
Yikhompawundi ephilayo ene-chemical formula C7H3BrF4. Lulwelo olungenambala ukuya kumthubi oluluthuthu olunevumba elikhethekileyo kubushushu begumbi.
Indalo:
1. indawo yokunyibilika:-33 ℃
2. Indawo yokubilisa: 147-149 ℃
3. Ubuninzi: 1.889g/cm³
4. I-Solubility: I-Soluble kwii-solvents ze-organic ezifana ne-ether, i-ethanol kunye ne-dichloromethane, i-soluble emanzini.
Sebenzisa:
Isetyenziswa ikakhulu njengendawo ephakathi kwi-organic synthesis. Ngokuqhelekileyo isetyenziswe kwi-chiza synthesis, i-catalysis yeekhemikhali kunye nezinto eziphilayo, ezifana ne-benzopyrazolones, i-cyclic macrocyclization, i-organic photoelectric materials synthesis, njl.
Indlela yokulungiselela:
Indlela yokulungiselela i-calcium ikakhulu ngokusabela kwe-bromobenzene kunye ne-trifluorotoluene phantsi kweemeko ezifanelekileyo. Ngesiqhelo, i-bromobenzene idibana ne-trifluorotoluene xa kukho umgubo wobhedu okanye ikomityi phantsi kokufudumeza ukwenza i-fluorotoluene.
Ulwazi ngoKhuseleko:
Iyacaphukisa kwaye kufuneka igweme ukudibana ngqo nolusu kunye namehlo. Izixhobo zokukhusela zomntu ezifana neeglavu zokukhusela, iiglasi kunye nempahla yokukhusela kufuneka inxibe ngexesha lokusetyenziswa kunye nokuphathwa. Kuphephe ukuphefumla umphunga wayo kwaye uqinisekise ukuba usebenza kwindawo engenamoya. Ukongeza, kufuneka igcinwe kwisitya esivaliweyo, kude nobushushu kunye nemithombo yomlilo. Xa usebenzisa okanye ulahla, nceda ulandele iinkqubo ezifanelekileyo zokhuseleko. Ukuba kukho ukuvuza, kufuneka kuthathwe amanyathelo afanelekileyo okucoca kunye nokulahla. Ukuba kuyimfuneko, ingcali kufuneka idibane.
