Isingeniso
I-2,5-Dichloronicotinic acid iyinhlanganisela ye-organic enefomula yamakhemikhali i-C6H3Cl2NO2, esebenzisa ukucushwa kwesithonjana se-imidazole esakhiweni sayo sikadayi imidazolyl. Okulandelayo ezinye zezakhiwo eziyinhloko ze-2,5-Dichloronicotinic acid:
Imvelo:
-Ukubukeka: Okuqinile okucwebezelayo okumhlophe kuya kokuphuzi okuphaphathekile.
-Indawo yokuncibilika: cishe ku-207-208°C.
-Ukunyibilika: Kuncibilika kancane emanzini, kuncibilika kuzincibilikisi zemvelo ezifana notshwala, i-ether, i-chloroform, njll.
-Ukuzinza: kuzinzile kumazinga okushisa asekamelweni.
Sebenzisa:
- I-2,5-Dichloronicotinic acid ingasetshenziswa njengendawo ephakathi ku-organic synthesis futhi isetshenziswa kabanzi ekulungiseleleni ama-organic compounds ahlukahlukene kanye nezibulala-zinambuzane.
-Ingasetshenziswa futhi njenge-ligand equkethe i-ion yensimbi yokuhlanganiswa kwezakhiwo zensimbi zenguquko.
Ukulungiselela:
- I-2,5-Dichloronicotinic acid ingalungiswa nge-chlorinating nicotinic acid. Indlela ethile ingase ibe ukusabela i-nicotinic acid ne-thionyl chloride ezingeni lokushisa eliphezulu, kulandele ukupholisa ikristalu ukuze kutholwe umkhiqizo.
Ulwazi Lokuphepha:
- I-2,5-Dichloronicotinic acid inezinga elithile lokucasuka, ngakho-ke udinga ukunaka ukuvikela ngesikhathi sokusebenza.
-Ubuthi nobungozi be-2,5-Dichloronicotinic acid budinga ucwaningo olujulile nokuhlolwa ukuze kutholakale ukuphepha kwayo kanye nezingozi ezithile. Ngakho-ke, ekusebenzeni nasekusetshenzisweni, kunconywa ukulandela izinqubo zokuphepha ezifanele futhi uthathe izinyathelo zokuzivikela ezifanele.
