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

Intshayelelo

I-Ethyl, ifomula yeekhemikhali yi-C9H9NO4. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:

Indalo:

I-Ethyl yikristale ephuzi okanye ipowder enembonakalo enamafutha kunye nephunga elikhethekileyo. Iyanyibilika kwiintlobo ezininzi zezinyibilikisi zendalo kwaye ayinyibiliki kangako emanzini.

Sebenzisa:

I-Ethyl yi-organic synthesis intermediate compound, esetyenziswa ngokubanzi kwimimandla ye-pesticide kunye nokuveliswa kwamayeza. Ingasetyenziselwa ukudibanisa iintlobo ngeentlobo zeekhemikhali ezisebenza ngokwebhayoloji, njengezibulali-zinambuzane, imichiza yokungunda, amachiza okulwa nethumba, njl.njl.

Indlela yokulungiselela:

I-Ethyl idla ngokulungiswa nge-chemical synthesis. Enye indlela eqhelekileyo yi-esterification ye-2-methyl-5-nitronicotinic acid. Kwintsebenzo ethile, i-2-methyl-5-nitronicotinic acid iphendulwa nge-anhydride kunye ne-alkaline catalyst ukuvelisa i-Ethyl.

Ulwazi ngoKhuseleko:

I-Ethyl inokucaphukisa ulusu kwaye ibe yingozi emehlweni, umgudu wokuphefumula kunye nokuphefumula. Ngoko ke, amanyathelo afanelekileyo okukhusela kufuneka athathwe xa uphatha into, njengokugqoka iiglavu kunye neeglasi zokukhusela, ukuqinisekisa ukuba umsebenzi uqhutyelwa phantsi kweemeko zomoya. Ukongeza, kufuneka igcinwe kwindawo eyomileyo, epholileyo, engenamoya, kude nezinto ezinokutsha kunye ne-oxidants. Nceda ujonge kwidatha efanelekileyo yokhuseleko kunye nemiyalelo yokusebenza yayo nayiphi na imisebenzi yokhuseleko enxulumene nale nto.
