Synthesis thiab reactivity

Tom qab thawj zaug sim cov synthesis hauv 1903, Otto Ruff tau npaj nitrogen trifluoride los ntawm electrolysis ntawm ib tug molten sib tov ntawm ammonium fluoride thiab hydrogen fluoride.

Ntxiv rau qhov no, nitrogen trifluoride ua li cas?

NF3 Ntau Lawm los ntawm Electrolysis hauv Molten Fluorides Piv txwv li, nitrogen trifluoride (NF3) yog cov pa ruaj khov ntawm chav tsev kub thiab muaj zog oxidation zog ntawm qhov kub siab dua [3-5]. Txog li 200 ° C, nws cov reactivity piv rau oxygen. Tshaj 400 ° C, lub reactivity ntawm NF3 ua zoo li fluorine.

Ib tug kuj yuav nug, hom ntawv cog lus twg yog nitrogen trifluoride? Lub molecule muaj ib tug trigonal pyramidal qauv, zoo li ammonia. Cov daim ntawv cog lus lub kaum sab xis yog txo los ntawm 107 ° hauv ammonia rau 101.9 ° hauv NF3, vim tias cov fluorine electronegative heev rub cov electrons hauv N-F daim ntawv cog lus ntawm lawv tus kheej, txo qis interelectronic repulsions, kom NF3 'umbrella' kaw.

Ntxiv mus, dab tsi yog cov tshuaj formula rau nitrogen trifluoride?

NF3

Puas yog nf3 yog oxidizer?

Nitrogen Trifluoride ( NF3 ) yog kev txaus siab raws li ib tug oxidizer ntawm cov roj hluav taws xob siab, rau kev npaj ntawm tetrafluorohydrazine, thiab rau fluorination ntawm fluorocarbon olefins. Ib qho tsis muaj xim, tsis muaj hluav taws xob, cov roj liquefied nrog cov ntxhiab tsw. Muaj tshuaj lom; Irritates cov huab cua. Ib tug muaj zog oxidizer.
