Isingeniso
I-2,5-Dichloropyridin-3-amine iyinhlanganisela ye-organic enefomula yamakhemikhali i-C5H3Cl2N. Ayinambala noma iyikristalu ephuzi ephaphathekile, inephunga elimnandi elinamandla. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: Ikristalu eliphuzi elingenambala noma elikhanyayo
-Ukunyibilika: Kuncibilika kancane emanzini, kuncibilika kuzincibilikisi eziningi eziphilayo
-indawo yokuncibilika: mayelana ne-104-106 ℃
-Iphuzu elibilayo: mayelana ne-270 ℃ (inani eliyinkomba)
Sebenzisa:
- I-2,5-Dichloropyridin-3-amine ingasetshenziswa njengendawo ephakathi kwe-organic synthesis futhi isetshenziswa kabanzi emithini, izibulala-zinambuzane nakweminye imikhakha.
-Ingase futhi isetshenziselwe ukulungisa ama-compounds asebenzayo, ama-dyes kanye nama-coordination compounds.
Indlela Yokulungiselela:
Indlela evamile yokulungiselela ukusabela kwe-2,5-dichloropyridine nge-ammonia:
2,5-Dichloropyridinamine → 2,5-Dichloropyridin-3-amine
Ulwazi Lokuphepha:
- I-2,5-Dichloropyridin-3-amine iyacasula, sicela uqaphele ukugwema ukuthintana nesikhumba, amehlo kanye nesistimu yokuphefumula. Izinto ezisetshenziswayo zokuvikela ezifanele njengamagilavu, izibuko kanye nemaski kufanele zigqokwe ngesikhathi sokusetshenziswa.
-Gwema umlilo kanye nokushisa okuphezulu ngesikhathi sokusebenzisa nokugcina ukuze uvimbele ukuthi ungashi noma uqhume.
Sicela uqaphele ukuthi lapho usebenzisa futhi uphatha amakhemikhali, kufanele ulandele izinqubo zokusebenza eziphephile futhi ulandele imithethonqubo efanele kanye neziqondiso ukuze uqinisekise ukuphepha komuntu siqu kanye nemvelo.
