2-Chloro-3-Nitro-5-Bromo-6-Picoline (CAS# 186413-75-2) Selelekela

CNBMP, ka bokhutšoanyane, ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa sebopeho, tšebeliso, tlhahiso le tlhaiso-leseling ea polokeho ea CNBMP:Tlhaho:
-Ponahalo: CNBMP ke kristale e se nang 'mala kapa e mosehla hanyane.
- Sebaka sa ho qhibiliha: Sebaka sa ho qhibiliha sa CNBMP se pakeng tsa 148-152 likhato tsa Celsius.
-Solubility: CNBMP e na le solubility e ntle ka har'a li-solvents, empa ho qhibiliha ho tlase metsing.

Sebelisa:
- CNBMP e sebelisoa haholo e le li-intermediate tsa meriana le chefo e bolaeang likokoanyana. E ka sebelisoa e le lisebelisoa tse tala bakeng sa ho kopanya lithethefatsi tse ling le chefo e bolaeang likokoanyana, joalo ka lithethefatsi tse khahlanong le mofetše, lithibela-mafu le chefo e bolaeang likokoanyana.
-Hobane CNBMP e na le lisebelisoa tse khethehileng tsa lik'hemik'hale, e ka boela ea sebelisoa ha ho etsoa li-dyes, lipente le li-pigment tse ling.

Mokhoa:
- CNBMP e ka lokisoa ka karabelo ea lik'hemik'hale. Mokhoa o mong o tloaelehileng oa ho lokisa ke ka condensation ea 2-bromo-3-nitro-5-chloro-6-methylpyridine le sodium bromide. Karabelo ka kakaretso e etsoa ka har'a mokelikeli o phelang ka mocheso o loketseng le pH.

Lintlha tsa Tšireletseho:
- CNBMP ke motsoako oa manyolo, kahoo o hloka ho ba hlokolosi ha o e sebelisa le ho e tšoara. E ka halefisa le ho ba kotsi, kahoo ho lokela ho nkoa mehato e loketseng ea tšireletso, e kang ho roala liatlana tse sireletsang lik'hemik'hale le tšireletso ea phefumoloho.
-Nakong ea polokelo le lipalangoang, CNBMP e lokela ho qoba ho kopana le li-oxidants, li-acids tse matla le metheo e matla ho thibela liketso tse kotsi.
-Ho phaella moo, ha ho lahla litšila tsa CNBMP, ho lokela ho lahloa ka mokhoa o nepahetseng ho latela melao ea sebaka seo ho netefatsa tšireletso ea tikoloho le batho.

Ka kopo hlokomela hore CNBMP ke motsoako oa lintho tse phelang, 'me tšebeliso e nepahetseng le ho sebetsana le eona ke tsa bohlokoa haholo. Pele o sebelisoa, ka kopo tseba ka polokeho ea eona le litataiso tsa tšebeliso, 'me u latele mekhoa ea liteko.
