2-Bromo-5-chloro-3-picoline ke motsoako oa tlhaho o nang le foromo ea lik'hemik'hale C7H6BrClN. E latelang ke tlhaloso ea thepa, tšebeliso, tokiso le tlhaiso-leseling ea polokeho ea komporo:
Tlhaho:
-Ponahalo: 2-Bromo-5-chloro-3-picoline ke mokelikeli o se nang 'mala kapa o mosehla hanyenyane.
-Solubility: E qhibiliha ka har'a metsoako e mengata ea lintho tse phelang, tse kang ethanol, dimethylformamide le chloroform.
-Ntho ea ho qhibiliha le ntlha e belang: Sebaka sa ho qhibiliha sa motsoako se ka bang -35 ° C, 'me ntlha e belang e ka bang 205-210 ° C.
Sebelisa:
- 2-Bromo-5-chloro-3-picoline e ka sebelisoa e le ntho e qalang kapa e bohareng ea motsoako oa organic, 'me e ka sebelisoa ho kopanya metsoako e meng, joalo ka chefo e bolaeang likokoanyana le lithethefatsi.
-E boetse e sebelisoa haholo ho li-intermediates tsa maiketsetso, li-biphenyls tse nang le polychlorinated, li-biphenyls tse nang le polybrominated le li-pigments.
Mokhoa oa ho itokisa:
- 2-Bromo-5-chloro-3-picoline hangata e lokiselitsoe ke bromination le chlorination ea 3-picoline. Ntlha ea pele, 3-methylpyridine e sebetsanoa le hydrogen bromide ho fumana 2-bromo-5-methylpyridine, ebe sehlahisoa se itšoara ka tšepe ea chloride catalyst ho fumana sehlahisoa se lebisitsoeng.
Lintlha tsa Tšireletseho:
- 2-Bromo-5-chloro-3-picoline ka kakaretso ha e bake kotsi e kholo tlas'a maemo a tloaelehileng a tšebeliso. Leha ho le joalo, e ka 'na ea halefisa mahlo, letlalo le pampiri ea ho hema, kahoo ho lokela ho nkoa tlhokomelo ho qoba ho kopana ka ho toba.
- Sebelisa ka lisebelisoa tse nepahetseng tsa ts'ireletso, joalo ka liatlana tsa lik'hemik'hale, likhalase le lithebe tsa sefahleho.
- Mekhoa e metle ea laboratori e lokela ho lateloa nakong ea tšebeliso le moea o motle o lokela ho bolokoa.
- Qoba ho kopana le li-oxidants tse matla le li-acid tse matla nakong ea ho tšoara le ho boloka.
