Selelekela
2,3-dibromo-5-methylpyridine (2,3-dibromo-5-methylpyridine) ke motsoako oa motsoako o nang le motsoako oa lik'hemik'hale C6H5Br2N. E latelang ke tlhaloso ea sebopeho sa eona, ts'ebeliso, tokiso le tlhaiso-leseling ea polokeho:
Tlhaho:
2,3-dibromo-5-methylpyridine ke 'mala o mosehla o nang le monko o monate. E na le ntlha e qhibilihang e ka bang likhato tse 63-65 tsa Celsius le ntlha e belang e ka bang likhato tse 269-271 tsa Celsius. Ha e qhibilihe ka metsing, 'me ha e qhibilihe ka har'a metsoako ea tlhaho.
Sebelisa:
2,3-dibromo-5-methylpyridine ke motsoako o fapaneng oa organic synthesis bohareng. E ka sebelisoa ho kopanya metsoako e meng ea manyolo, joalo ka lintho tse tsoang ho lintho tse sebetsang ka tlhaho, lithethefatsi le chefo e bolaeang likokoanyana. E ka boela ea sebelisoa bakeng sa ho kopanya thepa ea lisebelisoa tsa elektroniki tse kang organic light-emitting diode (OLED) le libeteri tsa tlhaho.
Mokhoa:
2,3-dibromo-5-methylpyrridine e ka fumanoa ka ho itšoara ka 5-methylpyridine ka bromine. 5-Methylpyridine e qala ho itšoara ka hydrogen bromide, ebe e tsoela pele ho itšoara ka methyl chloride ka pel'a sekontiri ho hlahisa sehlahisoa se lebisitsoeng.
Lintlha tsa Tšireletseho:
2,3-dibromo-5-methylpyrridine e halefisa 'me e ka baka ho halefisoa ke mahlo, letlalo le tsamaiso ea ho hema. Nakong ea ts'ebeliso, ts'ebetso e sireletsehileng ea ts'ebetso e lokela ho hlokomeloa ka tieo, ho kopana ka kotloloho le letlalo le mahlo ho lokela ho qojoa, 'me ts'ebetso e lokela ho netefatsoa sebakeng se nang le moea o motle. Nakong ea ho tšoara le ho boloka, tlhokomelo e lokela ho nkoa ho qoba ho kopana le li-oxidants le thepa e tukang ho thibela kotsi ea mollo le ho phatloha. Haeba u hema kapa u pepesehetse motsoako ona, batla keletso ea bongaka hang-hang 'me u buisane le ngaka ea setsebi.
