Qhov txawv ntawm N2O4 thiab NO2 yog N2O4 yog diamagnetic, whereas NO2 yog paramagnetic.
N2O4 yog dinitrogen tetroxide thaum NO2 yog nitrogen dioxide. Txawm hais tias cov tshuaj formula N2O4 tuaj yeem tau los ntawm ob npaug ntawm qhov tseem ceeb stoichiometric ntawm cov tshuaj formula NO2, ob qho no yog cov tshuaj sib txawv sib txawv nrog cov tshuaj sib txawv thiab lub cev.
N2O4 yog dab tsi?
N2O4 yog dinitrogen tetroxide. Peb feem ntau hu nws ua nitrogen tetroxide. Cov tshuaj no tshwm sim raws li cov kua tsis muaj xim thiab yog ib qho tseem ceeb heev reagent nyob rau hauv cov txheej txheem chemical synthesis. Qhov kev sib xyaw no tuaj yeem tsim qhov sib npaug sib xyaw nrog nitrogen dioxide. Tsis tas li ntawd, dinitrogen tetroxide yog ib qho muaj zog oxidizing tus neeg sawv cev uas yog hypergolic ib yam nkaus. Nws yog hypergolic thaum sib cuag nrog ntau hom hydrazine (qhov no ua rau cov sib xyaw ntawm hydrazine thiab dinitrogen tetroxide ib hom bipropellant rau foob pob ua ntxaij).
Daim duab 01: Molecular Buildup ntawm Dinitrogen Tetroxide Molecule
Peb tuaj yeem txiav txim siab txog dinitrogen tetroxide molecule ua ob pawg nitro uas sib koom ua ke. Thiab, qhov tshwj xeeb cov tshuaj tiv thaiv no tsim ib qho sib npaug sib xyaw ntawm dinitrogen tetroxide thiab nitrogen dioxide. Tsis tas li ntawd, peb tuaj yeem soj ntsuam cov dinitrogen tetroxide molecule raws li cov qauv qauv uas muaj qhov tsis muaj zog ntawm ob lub atoms nitrogen. Nws yog vim tias daim ntawv cog lus tshuaj no tau ntev dua li N-N tshuaj daim ntawv cog lus ib txwm.
Thaum xav txog cov khoom sib nqus ntawm cov molecule no, nws yog diamagnetic vim tias tsis muaj cov hluav taws xob tsis sib xws ntawm ib qho atom ntawm cov molecule no. Ntxiv mus, cov kua dej no feem ntau tsis muaj xim, tab sis tuaj yeem muaj xim daj thiab vim muaj NO2 nyob ntawm qhov sib npaug uas tau hais los saum no. Qhov tseem ceeb tshaj, ntawm qhov kub siab, qhov sib npaug thawb mus rau NO2 es tsis yog N2O4.
Dinitrogen tetroxide tuaj yeem tsim los ntawm catalytic oxidation ntawm ammonia, qhov twg chav siv los ua diluent kom txo qhov kub thiab txias. Hauv cov txheej txheem tshuaj tiv thaiv no, thawj kauj ruam suav nrog ammonia oxidation rau hauv nitric oxide, thiab theem thib ob yog oxidation ntawm nitric oxide rau hauv nitrogen dioxide, ua raws li dimerization rau hauv nitrogen tetroxide.
NO2 yog dab tsi?
NO2 yog nitrogen dioxide. Nws yog ib qho ntawm ntau cov nitrogen oxides. Peb tuaj yeem soj ntsuam nws ua ib qho nruab nrab hauv kev lag luam synthesis ntawm nitric acid, uas yog ib qho tseem ceeb hauv kev tsim cov chiv. Tsis tas li ntawd, NO2 yog cov roj av xim av uas muaj cov ntxhiab tsw zoo li chlorine. Thaum ntxiv rau dej, qhov sib xyaw no ua rau hydrolysis. Txawm li cas los xij, cov khoom no gaseous hloov mus rau hauv cov kua daj-xim av ntawm qhov kub thiab txias. Thiab, qhov kev hloov xim no tshwm sim vim kev hloov pauv ntawm NO2 rau N2O4.
Daim duab 02: Cov Qauv Tshuaj ntawm NO2
yam ntxwv, cov nitrogen atom ntawm NO2 molecule muaj ib qho hluav taws xob tsis sib xws thaum muaj ob daim ntawv cog lus N=O hauv cov molecule. Yog li ntawd, qhov no compound yog paramagnetic; lub ntsiab lus, nws tuaj yeem tau txais kev nyiam rau sab nraud magnetic teb. Tsis tas li ntawd, ib qho hluav taws xob tsis sib xws kuj txhais tau tias nws yog cov dawb radical compound.
Thaum xav txog kev npaj ntawm NO2 cov khoom, nws feem ntau tsim los ntawm oxidation ntawm nitric oxide los ntawm oxygen hauv huab cua. Tsis tas li ntawd, cov tshuaj no tsim nyob rau hauv feem ntau cov txheej txheem combustion siv huab cua ua tus neeg sawv cev oxidizing.
Muaj qee qhov sib txawv ntawm NO2, suav nrog kev siv nws los ua ib qho nruab nrab hauv kev tsim cov nitric acid, ua tus neeg sawv cev nitrating hauv kev tsim cov tshuaj tawg, ua polymerization inhibitor rau acrylates, ua hmoov bleaching. tus neeg sawv cev, thiab lwm yam.
Qhov txawv ntawm N2O4 thiab NO2 yog dab tsi?
N2O4 yog dinitrogen tetroxide thaum NO2 yog nitrogen dioxide. Qhov sib txawv tseem ceeb ntawm N2O4 thiab NO2 yog N2O4 yog diamagnetic, hos NO2 yog paramagnetic. Tsis tas li ntawd, N2O4 tshwm sim ua kua, thaum NO2 yog cov khoom siv roj. Ntxiv mus, N2O4 yog cov kua tsis muaj xim thaum NO2 yog cov roj av xim av.
Cov ntaub ntawv hauv qab no-daim duab tabulates ntau qhov sib txawv ntawm N2O4 thiab NO2 rau ib sab ntawm kev sib piv.
Summary – N2O4 vs NO2
N2O4 yog dinitrogen tetroxide. NO2 yog nitrogen dioxide. Thaum xav txog cov khoom siv tshuaj ntawm ob lub tebchaw, cov khoom sib nqus yog qhov tseem ceeb heev. Qhov sib txawv tseem ceeb ntawm N2O4 thiab NO2 yog N2O4 yog diamagnetic, hos NO2 yog paramagnetic. Diamagnetic txhais tau hais tias N2O4 molecules tsis nyiam rau sab nraud magnetic teb vim tias tsis muaj cov hluav taws xob tsis sib xws hauv cov molecule no. Paramagnetic txhais tau hais tias cov molecule yog attracted rau ib sab magnetic teb vim hais tias muaj ib tug unpaired electron nyob rau hauv lub NO2 molecule.
