2 3-DIBROMO-5-CHLORO PYRIDINE (CAS# 137628-17-2) isingeniso
I-2,3-dibromo-5-chloropyridine i-organic compound. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela, kunye nolwazi lokhuseleko lwekhompawundi:
indalo:
-Ukubonakala: I-2,3-dibromo-5-chloropyridine yinto eqinileyo engenambala ukuya emthubi.
-I-Solubility: Ine-solubility ephezulu kwii-solvents eziphilayo kodwa i-solubility ephantsi emanzini.
Injongo:
I-2,3-dibromo-5-chloropyridine inoluhlu olubanzi lwezicelo kwi-organic synthesis, esetyenziswa kakhulu kwezi ndawo zilandelayo:
-Njenge-photosensitizer, ingasetyenziswa kwiinkalo ezifana nokuprinta kunye nokuveliswa kweefoto.
Indlela yokuvelisa:
Indlela yokulungiselela i-2,3-dibromo-5-chloropyridine inokuqhutywa ngala manyathelo alandelayo:
Ngaphantsi kweemeko ezifanelekileyo, phendula i-2,3-dibromopyridine kunye ne-phosphorus pentachloride ukuvelisa i-2,3-dibromo-5-chloropyridine pentachloride.
Emva koko, phendula i-pentachloride kunye ne-sodium hydroxide okanye ezinye izisombululo ze-alkaline ukuze ufumane i-2,3-dibromo-5-chloropyridine.
Ulwazi lokhuseleko:
-Ukusetyenziswa kunye nokusebenza kwe-2,3-dibromo-5-chloropyridine kufuneka kuqhutywe kwindawo epholileyo ukuze kugwenywe ukutshatyalaliswa kwexesha elide kwiphunga okanye uthuli.
-Ngexesha lokusebenza, izixhobo ezifanelekileyo zokukhusela kufuneka zinxitywe, kubandakanywa iiglavu zokukhusela iikhemikhali, izibuko, kunye nempahla yokukhusela.
-2,3-dibromo-5-chloropyridine yeyobomi be-bromides kwaye inetyhefu ethile kunye nokucaphuka. Kufuneka iphathwe kwaye igcinwe ngokufanelekileyo ukuphepha ukudibanisa nezinto ezinokutsha kunye namaqondo obushushu aphezulu.
-Xa usebenzisa kwaye ulahla le khompawundi, nceda ulandele iimfuno zeenkqubo zokusebenza zokhuseleko kunye nemithetho efanelekileyo kunye nemimiselo.
