3 5-DIBROMO-4-CHLOROPYRIDINE (CAS# 13626-17-0)isingeniso
I-4-chloro-3,5-dibromopyridine (eyaziwa nangokuthi i-4-chloro-3,5-dibromopyridine) iyinhlanganisela yezinto eziphilayo. Okulandelayo ulwazi mayelana nezakhiwo, ukusetshenziswa, izindlela zokulungiselela, nokuphepha kwenhlanganisela:
imvelo:
-Ukubukeka: I-4-chloro-3,5-dibromopyridine iyi-crystal engenambala ephuzi noma i-crystalline powder.
-Ukuncibilika: Ayincibiliki emanzini, kodwa incibilika kuzincibilikisi zemvelo ezifana ne-ethanol, i-acetone, ne-ether.
-Izakhiwo zamakhemikhali: Kuyisisekelo esibuthakathaka esingabhekana nokusabela okushintshwayo, i-hydrogen bonding, kanye nokusabela kwe-succinyl nucleophilic.
Inhloso:
-Ingasetshenziswa futhi njenge-reagent kuma-laboratories amakhemikhali.
Indlela yokukhiqiza:
-4-chloro-3,5-dibromopyridine ingahlanganiswa ngokungeza i-cuprous chloride (CuCl) ku-3,5-dibromopyridine kanye nokushisisa ukusabela.
-Indlela ethile yokuhlanganisa ingase ilungiswe njengoba kudingeka, njengoba indlela yokuhlanganiswa kwezinhlanganisela ingathuthukiswa ngokuvumelana nezimo ezihlukahlukene kanye nezidingo zokusabela.
Ulwazi lokuphepha:
-4-chloro-3,5-dibromopyridine inobuthi obuthile emzimbeni womuntu, futhi ukuthintana noma ukuhogela kungabangela ukucasuka nokulimala.
-Izinyathelo zokuphepha ezifanele kufanele zithathwe uma usebenzisa noma uphatha inhlanganisela, njengokugqoka amagilavu okuzivikela, izibuko, nezingubo zokuzivikela.
-Sicela ufunde futhi ulandele imanuwali yokusebenza kokuphepha kwamakhemikhali afanele ngaphambi kokusetshenziswa, futhi wenze izivivinyo ngaphansi kwezimo ezifanele.
