Intshayelelo
I-2,3-dibromo-5-methylpyridine (2,3-dibromo-5-methylpyridine) i-organic compound kunye ne-chemical formula C6H5Br2N. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:
Indalo:
I-2,3-dibromo-5-methylpyridine iqinile etyheli kunye nevumba elimnandi. Ineqondo lokunyibilika elimalunga nama-63-65 ngokukaCelsius kunye neqondo lokubila elimalunga nama-269-271 ngokukaCelsius. Ayinyibiliki emanzini kwaye iyanyibilika kwizinyibilikisi zendalo.
Sebenzisa:
I-2,3-dibromo-5-methylpyridine yinto ephakathi kwe-organic synthesis. Ingasetyenziselwa ukudibanisa ezinye iikhompawundi eziphilayo, ezifana nezinto eziphuma kwi-biologically active substance, iziyobisi kunye nezibulali-zinambuzane. Inokusetyenziselwa ukuhlanganiswa kwezinto zombane ezifana ne-organic light-emitting diode (OLED) kunye neebhetri eziphilayo.
Indlela:
I-2,3-dibromo-5-methylpyrridine inokufumaneka ngokuphendula i-5-methylpyridine nge-bromine. I-5-Methylpyridine iqala ukusabela nge-hydrogen bromide, kwaye emva koko iyaqhubeka isabela nge-methyl chloride phambi kwe-catalyst ukuvelisa imveliso ekujoliswe kuyo.
Ulwazi ngoKhuseleko:
I-2,3-dibromo-5-methylpyrridine iyacaphukisa kwaye inokubangela ukucaphuka kwamehlo, ulusu kunye nenkqubo yokuphefumula. Ngexesha lokusetyenziswa, iinkqubo zokusebenza ezikhuselekileyo kufuneka ziqwalaselwe ngokungqongqo, ukudibana ngqo nesikhumba kunye namehlo kufuneka kugwenywe, kwaye ukusebenza kufuneka kuqinisekiswe kwindawo enomoya. Ngexesha lokuphatha kunye nokugcinwa, kufuneka kuthathelwe ingqalelo ukuphepha ukudibanisa ne-oxidants kunye nezinto ezinokutsha ukuthintela umngcipheko womlilo kunye nokuqhuma. Ukuba uphefumulelwe okanye ubonakaliswe kule khompawundi, funa iingcebiso zonyango ngokukhawuleza kwaye udibane nogqirha oqeqeshiweyo.
