Isingeniso

I-2-ETHOXY-5-NITROPYRIDINE iyinhlanganisela ye-organic ene-chemical formula C8H8N2O3.

 

Imvelo:

I-2-ETHOXY-5-NITROPYRIDINE iyikristale eqinile ephuzi enephunga elihlukile. Inephuzu lokuncibilika elicishe libe ngu-56-58 degrees Celsius kanye nephuzu lokubila eliba ngu-297-298 degrees Celsius. Ayincibiliki emanzini ekushiseni okuvamile, kodwa incibilika kuzincibilikisi zemvelo ezifana notshwala, i-ether, njll. Kuyinhlanganisela engazinzile ebola kalula ngaphansi kwezimo zokukhanya, ukushisa nezimo ezivusa amadlingozi.

 

Sebenzisa:

I-2-ETHOXY-5-NITROPYRIDINE ingasetshenziswa njengendawo ebalulekile ephakathi kwe-organic synthesis, esetshenziswa kabanzi ekuhlanganiseni kwamakhemikhali, imithi, amadayi nezinye izinkambu. Njengenhlanganisela yemisebenzi eminingi, ingasetshenziswa ukuhlanganisa ezinye izinhlanganisela, njengezidakamizwa, izibulala-zinambuzane namadayi.

 

Indlela:

I-2-ETHOXY-5-NITROPYRIDINE inezindlela eziningi zokulungiselela, enye yazo evame ukusetshenziswa ukusabela kwe-5-chloropyridine ne-ethyl alcohol ngaphansi kwezimo ze-alkaline. Izinyathelo ezithile zokwenziwa zidinga ukusebenza kokuhlolwa okuningiliziwe nolwazi lwamakhemikhali, sicela wenze ukusabela kokuhlanganiswa endaweni yaselabhorethri.

 

Ulwazi Lokuphepha:

I-2-ETHOXY-5-NITROPYRIDINE ingase ibangele ukucasuka lapho ithinta isikhumba namehlo, ngakho-ke kuyadingeka ukugqoka izinto zokuzivikela ezifanele ngesikhathi sokusebenza nokuphatha. Ngesikhathi esifanayo, inhlanganisela iqinile evuthayo futhi kufanele igcinwe kude nomlilo kanye nezinga lokushisa eliphezulu ukuze kugwenywe amagesi ayingozi kanye ne-vapor. Ngesikhathi sokugcina nokuphatha, bheka izinqubo zokuphepha ezifanele futhi uzigcine ezitsheni ezivaliwe. Uma kwenzeka kuba nengozi, sicela ngokushesha uthathe izinyathelo ezifanele eziphuthumayo futhi ufune usizo lwezokwelapha.
