Swarts fluorination yog txheej txheem uas cov tshuaj chlorine atoms nyob rau hauv ib qho chaw - feem ntau yog cov organic compound, tab sis kev sim tau ua los ntawm silanes - yog hloov nrog fluorine, los ntawm kev kho nrog antimony trifluoride nyob rau hauv lub xub ntiag ntawm chlorine los yog antimony pentachloride.
Yuav ua li cas hlau chloride siv rau hauv cov tshuaj tiv thaiv Swarts?
Swarts reagent yog dab tsi? Qhov sib xyaw ntawm antimony trifluoride (SbF 3) thiab chlorine(Cl2) yog lub npe hu ua Swarts reagent..
Vim li cas NAF tsis siv hauv Swarts cov tshuaj tiv thaiv?
Cov tshuaj tiv thaiv Swarts yog cov tshuaj tiv thaiv tseem ceeb heev los npaj alkyl fluoride indirect. Yog tias peb siv txoj kev ncaj nraim xws li lwm yam halogen los npaj fluoro alkane, fluorine tua cov alkane los tsim cov pa roj carbon thiab HF. Vim F2 muaj zog electronegative thiab nquag heev. Yog li alkyl fluoride tsis muaj.
Yuav ua li cas yog cov tshuaj fluoride yog siv nyob rau hauv cov tshuaj tiv thaiv Swartz?
Alkyl fluorides yog npaj los ntawm cua sov alkyl bromide los yog chloride nyob rau hauv muaj hlau fluoride xws li $AgF, Sb{F_3}$ los yog $H{g_2}{F_2}. $. Cov tshuaj tiv thaiv no hu ua Swarts cov tshuaj tiv thaiv. $C{H_3}Br + AgF \to C{H_3}F + AgBr$ yog ib qho piv txwv ntawm Swarts cov tshuaj tiv thaiv.
Dab tsi yog Swarts cov tshuaj tiv thaiv thiab Finkelstein cov tshuaj tiv thaiv?
Cov tshuaj tiv thaiv ntawm Swarts thiab Finkelstein yog halogen pauv kev cuam tshuam txog alkyl halides. Hauv cov tshuaj tiv thaiv no, sodium iodide (thenucleophile) raug kho nrog ethyl chloride (lub ntsiab alkyl halide) los tsim ethyl iodide.
