I-Ethyl 2-methyl-5-nitronicotinate (CAS# 51984-71-5)

Isingeniso

I-Ethyl, ifomula yamakhemikhali ithi C9H9NO4. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:

Imvelo:

I-Ethyl iyikristalu ephuzi noma impushana ebukeka inamafutha kanye nephunga elikhethekile. Iyancibilika kuma-solvents amaningi futhi ayincibiliki emanzini.

Sebenzisa:

I-Ethyl iyinhlanganisela ye-organic synthesis intermediate, esetshenziswa kabanzi emkhakheni wokukhiqiza izibulala-zinambuzane kanye nokukhiqizwa kwemithi. Ingasetshenziselwa ukuhlanganisa amakhemikhali ahlukahlukene asebenza ngokwebhayoloji, njengezibulala-zinambuzane, ama-fungicides, ama-anti-tumor drugs, njll.

Indlela Yokulungiselela:

I-Ethyl ivame ukulungiswa nge-chemical synthesis. Indlela eyodwa evamile i-esterification ye-2-methyl-5-nitronicotinic acid. Emsebenzini othize, i-2-methyl-5-nitronicotinic acid isabela nge-anhydride kanye ne-alkaline catalyst ukuze kukhiqizwe i-Ethyl.

Ulwazi Lokuphepha:

I-Ethyl ingase icasule isikhumba futhi ibe yingozi emehlweni, umgudu wokuphefumula kanye nomgudu wokuphefumula. Ngakho-ke, izinyathelo zokuzivikela ezifanele kufanele zithathwe lapho kusingathwa into, njengokugqoka amagilavu ​​nezibuko zokuzivikela, ukuze kuqinisekiswe ukuthi ukusebenza kwenziwa ngaphansi kwezimo ezinomoya omuhle. Ngaphezu kwalokho, kufanele igcinwe endaweni eyomile, epholile, enomoya omuhle, kude nezinto ezivuthayo kanye nama-oxidants. Sicela ubheke idatha efanele yokuphepha kanye nemiyalelo yokusebenza nganoma yikuphi ukuphepha okuhlobene nalesi sidakamizwa.
