Isingeniso
(3-bromo-5-fluorophenyl)i-methanol ingxube yemvelo enefomula yamangqamuzana ethi C7H6BrFO. Izici zayo zimi kanje:
1. Ukubukeka: uketshezi olungenambala noma okuqinile okuyikristalu.
2. Iphuzu Elincibilikayo: 50-53 ℃.
3. Iphuzu elibilayo: 273-275 ℃.
4. Ukuminyana: cishe ngu-1.61 g/cm.
5. Ukunyibilika: kuncibilika ku-ethanol, i-ether ne-ether, inyibilika kancane emanzini.
(3-bromo-5-fluorophenyl) ukusetshenziswa kwe-methanol:
1. Ukuhlanganiswa kwezidakamizwa: Njengengxenye ye-organic synthesis, ingasetshenziswa ukuhlanganisa izidakamizwa nezinye izinhlanganisela eziphilayo.
2. Ukwenziwa Kwezibulala-zinambuzane: zingasetshenziselwa ukukhiqizwa kwezibulala-sikhunta, izibulala-zinambuzane nezinye izibulala-zinambuzane.
3. Izimonyo: njengesinye sezithako ze-flavour nephunga.
Indlela Yokulungiselela:
(3-bromo-5-fluorophenyl)indlela yokulungiselela i-methanol ilula uma kuqhathaniswa, indlela evame ukusetshenziswa ukusabela kwe-3-bromo-5-fluorobenzaldehyde nge-sodium hydroxide, bese ihlanzwa futhi ifakwe amakristalu ukuze kutholwe umkhiqizo oqondiwe.
Ulwazi Lokuphepha:
1. Le nhlanganisela iyacasula futhi kufanele igweme ukuthintana nesikhumba, amehlo kanye nolwelwesi lwamafinyila.
2. Gqoka izinto zokuzivikela ezifanele njengezibuko, amagilavu nezingubo zaselabhorethri lapho uphatha noma usebenzisa.
3. Gwema ukuhogela umhwamuko noma uthuli lwawo, gcina umoya omuhle.
4. Gcina endaweni epholile, eyomile futhi engenawo umoya, kude nomlilo nezinto ezivuthayo.
5. Ngaphambi kokusetshenziswa noma ukulahlwa, izinqubo ezifanele zokusebenza zokuphepha kufanele zifundwe ngokuningiliziwe futhi zonke izinyathelo zokuphepha ezinqubweni zokusebenza kufanele zibhekwe.
