3-Bromo-2-fluoro-5-methylpyridine (CAS# 17282-01-8) Intshayelelo
lulwelo olungenambala ukuya kumthubi. Inevumba elibi kwiqondo lobushushu begumbi. Ubuninzi be-compound buphezulu, kwaye indawo yayo yokuncibilika kunye neqondo lokubilisa liyenyuka ngokunyuka komxholo we-bromine.
Sebenzisa:
Isetyenziswa ikakhulu njenge-reagent okanye ephakathi kwi-organic synthesis. Ingasetyenziswa ekulungiseleleni amayeza, i-pesticides kunye nezinye izinto eziphilayo. Isenokusetyenziswa njenge-reagent kuphando nakwiilabhoratri.
Indlela:
Indlela yokulungiselela ipilisi ikakhulu ibandakanya ukusabela kwamanyathelo amabini. Okokuqala, i-bromomethylpyridine iphendulwa kunye ne-potassium fluoride kwi-solvent ye-organic ukwazisa i-athomu ye-fluorine. Isiphumo se-bromofluoro ikhompawundi ke i-oxidized kwi-halogen ehambelana ne-hydrogen peroxide okanye ezinye ii-oxidizing agents.
Ulwazi ngoKhuseleko:
Yikhompawundi ephilayo kwaye kufuneka iphathwe ngononophelo. Ngexesha lokusetyenziswa okanye ukulungiselela, amanyathelo okhuseleko afanelekileyo kufuneka athathwe, njengokunxiba iiglavu zokhuselo zekhemikhali, iiglasi kunye neenkqubo zokukhuphela ngaphandle kwelabhoratri. Kuphephe ukudibana nolusu namehlo, kwaye uzigcine kude nomlilo. Xa ugcina, gcina isitya sivaliwe kwaye usibeke kwindawo epholileyo neyomileyo. Kwimeko yokungeniswa okanye ukudibana kwesikhumba, funa unyango ngokukhawuleza.
