Isingeniso
Kuyinhlanganisela yemvelo enefomula yamakhemikhali C7H3BrF4. Iwuketshezi oluphuzi olungenambala ukuya kokuphaphathekile olunephunga elikhethekile endaweni yokushisa.
Imvelo:
1. indawo encibilikayo:-33 ℃
2. Iphuzu elibilayo: 147-149 ℃
3. ukuminyana: 1.889g/cm³
4. Ukunyibilika: Kuncibilika kuzincibilikisi eziphilayo njenge-ether, i-ethanol ne-dichloromethane, engancibiliki emanzini.
Sebenzisa:
Isetshenziswa kakhulu njengengxenye ephakathi ku-organic synthesis. Ivame ukusetshenziswa ekuhlanganiseni kwezidakamizwa, i-catalysis yamakhemikhali nezinto eziphilayo, njenge-benzopyrazolones, i-cyclic macrocyclization, i-organic photoelectric materials synthesis, njll.
Indlela Yokulungiselela:
Indlela yokulungisa i-calcium ngokuyinhloko ibangelwa ukusabela kwe-bromobenzene ne-trifluorotoluene ngaphansi kwezimo ezifanele. Ngokuvamile, i-bromobenzene ihlangana ne-trifluorotoluene lapho kukhona impushana yethusi noma i-cuprous ngaphansi kokushisisa ukwenza i-fluorotoluene.
Ulwazi Lokuphepha:
Kuyacasula futhi kufanele kugweme ukuthintana ngqo nesikhumba namehlo. Izimpahla zokuzivikela ezifana namagilavu okuzivikela, izibuko nezingubo zokuzivikela kufanele zigqokwe ngesikhathi sokusetshenziswa nokuphathwa. Gwema ukuhogela umhwamuko wawo futhi uqiniseke ukuthi usebenza endaweni enomoya omuhle. Ngaphezu kwalokho, kufanele igcinwe esitsheni esivaliwe, kude nemithombo yokushisa nomlilo. Uma usebenzisa noma ulahla, sicela ulandele izinqubo zokuphepha ezifanele. Uma kuvuza, kufanele kuthathwe izinyathelo ezifanele zokuhlanza nokulahla. Uma kunesidingo, kufanele kuboniswane nochwepheshe.
