Isingeniso

I-2-Methoxy-5-aminopyridine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: I-2-methoxy-5-aminopyridine iyikristale eqinile engenambala.

- I-Solubility: Incibilika kuzincibilikisi ze-polar ezifana namanzi, utshwala nama-ether.

- Izakhiwo Zamakhemikhali: I-2-Methoxy-5-aminopyridine iyinhlanganisela ye-alkaline esabelana nama-acids ukwenza usawoti.

 

Sebenzisa:

- I-2-Methoxy-5-aminopyridine isetshenziswa kabanzi emkhakheni we-organic synthesis, ikakhulukazi ekuhlanganiseni kwemithi kanye nezibulala-zinambuzane.

- Emkhakheni wezibulala-zinambuzane, ingasetshenziswa ekulungiseni imikhiqizo ye-agrochemical efana nama-insecticides nama-herbicides.

 

Indlela:

Izindlela zokulungiselela ze-2-methoxy-5-aminopyridine zihluke kakhulu, futhi okulandelayo kuyindlela evamile yokulungiselela:

I-2-methoxypyridine isabela nge-ammonia eyeqile ku-solvent efanele, futhi ngemva kwesikhathi esithile sokusabela, izinga lokushisa nokulawulwa kwe-pH, umkhiqizo uthola i-crystallization, ukuhlunga, ukugeza nezinye izinyathelo zokuthola umkhiqizo ohlosiwe.

 

Ulwazi Lokuphepha:

- I-2-Methoxy-5-aminopyridine iyinhlanganisela yezinto eziphilayo, futhi kufanele kuthathwe izinyathelo ezifanele ngesikhathi sokuphatha, njengokugqoka amagilavu, izibuko, nezingubo zokuzivikela.

- Lapho ugcina futhi uphatha, kufanele ugcinwe kude nemithombo yomlilo nama-oxidants, futhi ugweme ukuthintana nama-acids aqinile, ama-alkali aqinile nezinye izinto.

- Lapho uthinta isikhumba noma amehlo, geza ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha.

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
