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

Cov tshuaj formula yog C7H5FN2O2, uas yog cov organic compound. Cov hauv qab no yog cov lus piav qhia ntawm nws qhov xwm txheej, kev siv, kev npaj thiab kev nyab xeeb cov ntaub ntawv: Xwm:
yog daj crystalline khoom. Nws muaj fluorine atom thiab ib pawg methyl hloov ntawm lub nplhaib pyridine, thiab ib pab pawg nitro hloov ntawm 3 txoj hauj lwm ntawm lub nplhaib pyridine. Nws muaj qhov melting point ntawm 177-180 degrees Celsius thiab ruaj khov ntawm chav tsev kub. Cov tshuaj no yog insoluble hauv dej, tab sis soluble hauv organic solvents xws li methanol, ethanol thiab dimethylformamide.Siv:
Nws yog ib qho tseem ceeb hauv cov organic synthesis. Nws feem ntau yog siv los ua ib qho nruab nrab hauv kev sib txuas ntawm lwm cov organic tebchaw. Tsis tas li ntawd, nws tseem tuaj yeem siv los ua cov tshuaj zas xim intermediates, tshuaj intermediates thiab tshuaj tua kab intermediates. Nws kuj yog qhov tawg me ntsis vim muaj nws cov nitro functional pawg.
Kev npaj cov calcium tuaj yeem tau los ntawm kev ua haujlwm pyridine nrog Methyl fluoride nyob rau hauv muaj sodium carbonate, ua raws li nitration. Cov kauj ruam tshwj xeeb npaj tuaj yeem xa mus rau cov ntaub ntawv organic synthesis.

Cov ntaub ntawv kev nyab xeeb:
Vim tias nws muaj cov pab pawg ua haujlwm nitro thiab tej zaum yuav tawg tau nyob rau hauv qee qhov xwm txheej, kev ntsuas kev nyab xeeb yuav tsum tau ua thaum lub sijhawm ua haujlwm. Tej zaum nws yuav muaj kev cuam tshuam rau lub qhov muag thiab tawv nqaij, yog li kev sib cuag ncaj qha yuav tsum tau zam thaum sib cuag. Nyob rau tib lub sijhawm, xyuam xim rau cov dej noo, hluav taws kub thiab kev tiv thaiv tawg thaum khaws cia thiab kev thauj mus los. Rau nws qhov tshwj xeeb siv thiab tuav, thov ua raws li cov lus qhia kev nyab xeeb ntawm cov tshuaj muaj feem xyuam thiab ua haujlwm raws li kev coj ua ntawm cov neeg ua haujlwm paub txog.
