2-Fluoro-6-methyl-3-nitropyridine (CAS# 19346-45-3)

Ifomula yeekhemikhali yi-C7H5FN2O2, eyona nto i-organic compound. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:Indalo:
yikristale etyheli eqinileyo. Ine-athomu ye-fluorine kunye neqela le-methyl elifakwe endaweni yeringi yepyridine, kunye neqela le-nitro elifakwe endaweni ye-3 yendawo ye-pyridine. Ineqondo lokunyibilika elimalunga ne-177-180 degrees Celsius kwaye izinzile kwiqondo lobushushu begumbi. Le khompawundi ayinyibiliki emanzini, kodwa inyibilika kwizinyibilikisi eziphilayo ezifana ne-methanol, i-ethanol kunye ne-dimethylformamide.Sebenzisa:
Kubalulekile kwi-organic synthesis. Ihlala isetyenziswa njengendawo ephakathi kwi-synthesis yezinye izinto eziphilayo. Ukongeza, inokuphinda isetyenziswe njengeziphakathi zedayi, i-pharmaceutical intermediates kunye ne-pesticide intermediates. Ikwaqhuma noko ngenxa yobukho beqela layo elisebenzayo le-nitro.Indlela:
Ukulungiswa kwe-calcium kunokufumaneka ngokuphendula i-pyridine kunye ne-Methyl fluoride phambi kwe-sodium carbonate, ilandelwa yi-nitration. Amanyathelo okulungiselela athile angabhekisa kuncwadi olufanelekileyo lwe-organic synthesis.

Ulwazi ngoKhuseleko:
Ngenxa yokuba ineqela elisebenzayo le-nitro kwaye linokuthi liqhume phantsi kweemeko ezithile, amanyathelo okhuseleko ahambelanayo kufuneka athathwe ngexesha lokusebenza. Inokuba nefuthe elicaphukisayo emehlweni kunye nolusu, ngoko ke ukudibana ngokuthe ngqo kufuneka kugwenywe xa udibana. Ngexesha elifanayo, nikela ingqalelo kumswakama, umlilo kunye nokukhusela ukuqhuma ngexesha lokugcinwa kunye nokuthutha. Ukusetyenziswa kwayo kunye nokuphathwa kwayo, nceda ulandele izikhokelo zokusebenza kokhuseleko lweekhemikhali ezifanelekileyo kwaye usebenze phantsi kwesikhokelo sabasebenzi abanamava.
