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

Ifomula yamakhemikhali ithi C7H5FN2O2, okuyinhlanganisela yemvelo. Okulandelayo yincazelo yobunjalo bayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:Imvelo:
iyikristale ephuzi eqinile. Ine-athomu ye-fluorine kanye neqembu le-methyl elifakwe endaweni ye-pyridine, kanye neqembu le-nitro elifakwe endaweni engu-3 yeringi ye-pyridine. Inephuzu lokuncibilika elicishe libe ngu-177-180 degrees Celsius futhi lizinzile ekamelweni lokushisa. Lesi sakhi asincibiliki emanzini, kodwa sincibilika kuzincibilikisi zemvelo ezifana ne-methanol, i-ethanol ne-dimethylformamide.Sebenzisa:
Kubalulekile ku-organic synthesis. Ivamise ukusetshenziswa njengendawo ephakathi ekuhlanganiseni ezinye izinto eziphilayo. Ngaphezu kwalokho, ingasetshenziswa futhi njengama-intermediates odayi, i-intermediate yezemithi kanye ne-pesticide intermediates. Iphinde iqhume ngenxa yokuba khona kweqembu layo elisebenzayo le-nitro.Indlela:
Ukulungiswa kwe-calcium kungatholakala ngokuphendula i-pyridine ne-Methyl fluoride phambi kwe-sodium carbonate, kulandelwa i-nitrate. Izinyathelo eziqondile zokulungiselela zingabhekisa ezincwadini ezifanele ze-organic synthesis.

Ulwazi Lokuphepha:
Ngenxa yokuthi ineqembu elisebenzayo le-nitro futhi ingase iqhume ngaphansi kwezimo ezithile, izinyathelo zokuphepha ezihambisanayo kufanele zithathwe ngesikhathi sokusebenza. Kungase kube nomthelela ocasulayo emehlweni nasesikhumbeni, ngakho ukuxhumana okuqondile kufanele kugwenywe lapho uthintana. Ngesikhathi esifanayo, qaphela umswakama, umlilo nokuvikelwa kokuqhuma ngesikhathi sokugcina nokuthutha. Ngokusetshenziswa kwayo okukhethekile nokubamba, sicela ulandele imihlahlandlela yokusebenza kokuphepha kwamakhemikhali afanelekile futhi usebenze ngaphansi kokuqondisa kwabasebenzi abanolwazi.
