Intshayelelo
(3-bromo-5-fluorophenyl) i-methanol yi-organic compound kunye ne-molecular formula C7H6BrFO. Iimpawu zayo zezi zilandelayo:
1. Imbonakalo: ulwelo olungenambala okanye oluqinileyo lwekristale.
2. Indawo enyibilikayo: 50-53 ℃.
3. Indawo yokubilisa: 273-275 ℃.
4. Ubuninzi: malunga ne-1.61 g / cm.
5. Ukunyibilika: ukunyibilika kwi-ethanol, i-ether kunye ne-ether, ukunyibilika kancinane emanzini.
(3-bromo-5-fluorophenyl) ukusetyenziswa kwemethanol:
1. I-Drug synthesis: Njenge-organic synthesis intermediate, ingasetyenziselwa ukudibanisa iziyobisi kunye nezinye izinto eziphilayo.
2. I-Pesticide Synthesis: ingasetyenziselwa ukuveliswa kwezibulali zinambuzane, izitshabalalisi kunye nezinye izitshabalalisi.
3. Izithambiso: njengenye yezithako zencasa kunye nevumba elimnandi.
Indlela yokulungiselela:
(I-3-bromo-5-fluorophenyl)indlela yokulungiselela i-methanol ilula, indlela esetyenziswa ngokuqhelekileyo kukusabela kwe-3-bromo-5-fluorobenzaldehyde nge-sodium hydroxide, emva koko ihlanjululwe kwaye igxininiswe ukufumana imveliso ekujoliswe kuyo.
Ulwazi ngoKhuseleko:
1. Le ngqungquthela iyacaphukisa kwaye kufuneka igweme ukudibanisa nesikhumba, amehlo kunye neembrane ze-mucous.
2. Nxiba izixhobo ezifanelekileyo zokuzikhusela njengeeglavu, iiglavu kunye nempahla yaselabhoratri xa uphethe okanye usebenzisa.
3. Gwema ukuphefumla umphunga okanye uthuli lwalo, gcina umoya omhle.
4. Gcina kwindawo epholileyo, eyomileyo nengena umoya, kude nomlilo kunye nezinto ezinokutsha.
5. Ngaphambi kokusetyenziswa okanye ukulahlwa, iinkqubo ezifanelekileyo zokusebenza zokhuseleko kufuneka zifundwe ngokubanzi kwaye onke amanyathelo okhuseleko kwiinkqubo zokusebenza kufuneka aqwalaselwe.
