Selelekela

4-Ethylpyridine ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea 4-ethylpyridine:

 

Boleng:

- Ponahalo: Mokelikeli o se nang 'mala kapa o tiileng oa kristale.

- Solubility: E qhibiliha ka har'a lihlapolli tse ngata tsa manyolo, ha e kenelle metsing.

 

Sebelisa:

- E le solvent: 4-ethylpyridine e na le solubility e ntle 'me e atisa ho sebelisoa e le motsoako oa ho qhibiliha kapa oa ho arabela, haholo-holo ho organic synthesis, e ka khothalletsang tsoelo-pele ea liketso.

- Catalyst: 4-ethylpyridine e ka boela ea sebelisoa e le sesosa sa karabelo e itseng ea lintho tse phelang, tse kang Grignard reagent reactions le hydrogenation reactions.

 

Mokhoa:

- 4-Ethylpyridine e ka lokisoa ka karabelo ea 2-ethylpyridine le ethyl acetate, hangata tlas'a maemo a alkaline.

 

Lintlha tsa Tšireletseho:

- 4-Ethylpyridine e ea halefisa 'me e ka baka ho teneha mahlong, letlalo le tsela ea ho hema. Apara lisebelisoa tse loketseng tsa ho itšireletsa ha u li tšoara 'me u qobe ho kopana ka ho toba le letlalo, mahlo, kapa likhase tse huloang.

- Ha o sebelisa kapa o boloka, boloka 4-ethylpyridine hole le mocheso o phahameng le malakabe a bulehileng.

- Ha ho lahla litšila, hoa hlokahala ho e lahla ho latela melao le melaoana ea sebaka seo ho qoba tšilafalo ea tikoloho.
