Isingeniso

I-2-Ethoxypyrimidine iyinhlanganisela yezinto eziphilayo.

 

I-2-Ethoxypyrazine iwuketshezi olungenambala olunephunga elincane elingavamile. Ayincibiliki kancane emanzini kodwa iyancibilika kuzincibilikisi eziningi eziphilayo.

I-2-ethoxypyrazine ingasetshenziswa futhi njengesibulala-zinambuzane kanye ne-antifungal agent. Uhlu olubanzi lwezicelo zamakhemikhali luyenza ibe enye yezinhlanganisela ezibalulekile emkhakheni wocwaningo nezimboni.

 

Indlela yokulungiselela i-2-ethoxypyrazine ngokuvamile itholakala ngokusabela kwe-2-aminopyrazine ne-ethanol. Ngesikhathi sokusebenza okukhethekile, i-2-aminopyrazine ichithwa ku-ethanol, bese i-dilute i-hydrochloric acid ingezwa kancane kancane, futhi i-ethanol eyeqile iyengezwa. Isixazululo sichithwa ukuze some ukuze kutholwe umkhiqizo we-2-ethoxypyrazine.

I-2-Ethoxypyrazine iyacasula futhi ukuthintana nesikhumba, amehlo, kanye nomgudu wokuphefumula kufanele kugwenywe. Gqoka izinto zokuzivikela ezifanele njengamagilavu, izibuko, namamaski lapho uphatha. Kufanele kuqashelwe ukuthi kugcinwe i-2-ethoxypyrazine endaweni eyomile, epholile, kude nokuvutha kanye nama-oxidants. Izinqubo ezifanele zokusebenza kanye nezinyathelo zokuphepha ezifanele kufanele zilandelwe lapho kusetshenziswa noma kusingathwa le nhlanganisela.

  • Okwedlule:

    • Bhala umyalezo wakho lapha futhi usithumelele wona
