Isingeniso
I-3,5-dichloro-4-amino Pyridine (3,5-dichloro-4-amino Pyridine) iyinhlanganisela ye-organic ene-chemical formula C5H4Cl2N2. Iqinile engenambala nephunga le-ammonia elibuthakathaka. Okulandelayo incazelo eningiliziwe yezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha kwenhlanganisela:
Imvelo:
-Ukubukeka: Okuqinile okungenambala
-I-Solubility: Incibilika ku-ethanol, i-dimethyl ether ne-chloroform, ayincibiliki emanzini
-Indawo yokuncibilika: mayelana ne-105-108 ° C
Isisindo samangqamuzana: 162.01g/mol
Sebenzisa:
-3,5-dichloro-4-amino Pyridine iyinhlanganisela ebalulekile ephakathi futhi inezinhlobonhlobo zokusetshenziswa ku-organic synthesis.
-Isetshenziswa kakhulu ekuhlanganiseni imithi, odayi kanye nezibulala-zinambuzane.
-3,5-dichloro-4-amino Pyridine ingasetshenziswa njengengxenye yokwenziwa yezibulala-zinambuzane, njengama-fungicides nama-insecticides.
Indlela:
-3,5-dichloro-4-amino Pyridine inezindlela eziningi zokulungiselela futhi ingahlanganiswa ngokusebenzisa iziteshi ezihlukahlukene.
-Indlela ejwayelekile yokulungiselela i-amination-chlorination reaction, elungiswa ngokusabela kwe-pyridine nge-aminating agent kanye ne-chlorinating agent.
-Izimo ezithile zokuhlola zingalungiswa ngokuvumelana nemibhalo ehlukene.
Ulwazi Lokuphepha:
-3,5-dichloro-4-amino Pyridine idinga ukuphathwa ngokucophelela futhi ilandele izinqubo zokusebenza eziphephile zaselabhorethri.
-Kuyinhlanganisela ecasulayo engase ibangele ukucasuka kwamehlo, isikhumba kanye nesistimu yokuphefumula.
-Ukugqoka izinto zokuzivikela ezifanele (njengezibuko, amagilavu nezingubo zokuzivikela) kuyanconywa ukuthi zisetshenziswe.
-Ukulahlwa kwemfucuza kuzohambisana namakhodi nemithetho yendawo.
