Isingeniso
I-2,3-dibromo-5-methylpyridine (2,3-dibromo-5-methylpyridine) iyinhlanganisela yemvelo enefomula yamakhemikhali C6H5Br2N. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
I-2,3-dibromo-5-methylpyridine iqinile ephuzi enephunga elimnandi. Inephuzu lokuncibilika elingama-degrees Celsius angama-63-65 kanye nephuzu lokubila eliba ngu-269-271 degrees Celsius. Ayincibiliki emanzini futhi iyancibilika kuma-organic solvents.
Sebenzisa:
I-2,3-dibromo-5-methylpyridine iyinhlanganisela ye-organic synthesis ephakathi nendawo. Ingasetshenziselwa ukuhlanganisa ezinye izinhlanganisela eziphilayo, ezifana nokuphuma kwezinto eziphilayo ezisebenzayo, izidakamizwa kanye nezibulala-zinambuzane. Ingase futhi isetshenziselwe ukuhlanganiswa kwezinto zezinto zikagesi ezifana ne-organic light-emitting diode (OLED) namabhethri aphilayo.
Indlela:
I-2,3-dibromo-5-methylpyrridine ingatholakala ngokusabela i-5-methylpyridine nge-bromine. I-5-Methylpyridine iqala ihlangana ne-hydrogen bromide, bese iqhubeka nokusabela nge-methyl chloride phambi kwe-catalyst ukukhiqiza umkhiqizo oqondiwe.
Ulwazi Lokuphepha:
I-2,3-dibromo-5-methylpyrridine iyacasula futhi ingabangela ukucasuka emehlweni, isikhumba kanye nesistimu yokuphefumula. Ngesikhathi sokusetshenziswa, izinqubo zokusebenza eziphephile kufanele zibhekwe ngokuqinile, ukuthintana ngqo nesikhumba namehlo kufanele kugwenywe, futhi ukusebenza kufanele kuqinisekiswe endaweni enomoya omuhle. Ngesikhathi sokuphatha nokugcinwa, ukunakekelwa kufanele kuthathwe ukuze kugwenywe ukuthintana nama-oxidants kanye nezinto ezivuthayo ukuze kuvinjelwe ingozi yomlilo nokuqhuma. Uma uhogelwe noma uvezwe kulesi sithako, funa iseluleko sezokwelapha ngokushesha futhi uthintane nodokotela ochwepheshe.
