Qhov sib txawv tseem ceeb ntawm ethyl nitrite thiab nitroethane yog nyob rau hauv ethyl nitrite, ib qho oxygen atom txuas mus rau carbon atom, thiab lwm cov pa atom yog txuas rau nitrogen atom, whereas nyob rau hauv nitroethane, ob qho tib si oxygen atoms yog bonded. rau nitrogen atom.
Ethyl nitrite thiab nitroethane muaj tib cov tshuaj formula: C2H5NO2. Lawv yog cov isomers ua haujlwm. Tab sis muaj ntau qhov sib txawv ntawm ethyl nitrite thiab nitroethane.
YEthyl Nitrite yog dab tsi?
Ethyl nitrite yog hom alkyl nitrite uas muaj cov tshuaj formula C2H5NO2. Nws tuaj yeem npaj los ntawm ethanol. Cov molar loj ntawm cov tshuaj no yog 75.067 g / mol. Nws tsis zoo soluble hauv dej, thiab nws qhov kub ntawm qhov kub yog 17 degrees Celsius.
Daim duab 01: Cov Qauv Tshuaj ntawm Ethyl Nitrite
Peb tuaj yeem siv ethyl nitrite ua cov tshuaj reagent nrog butanone kom tawm los dimethylglyoxime ua cov khoom kawg. Cov tshuaj no yog cov khoom xyaw tseem ceeb hauv cov tshuaj ethanol-raws li kev kho mob (rau cov mob khaub thuas thiab hnoos) npe hu ua Witdulsies, uas muaj keeb kwm South Africa, thiab nws yog ib qho tshuaj kho mob khaub thuas thiab mob khaub thuas. Hauv South Africa, nws tseem muag hauv khw muag tshuaj. Txawm li cas los xij, nws tau raug txwv tsis pub muag ntawm lub txee hauv Teb Chaws Asmeskas (Hauv Teb Chaws Asmeskas, nws yog lub npe hu ua qab zib nitrite, qab zib qab zib, lossis nitrite) txij li xyoo 1980. Qhov no yog vim nws cuam tshuam nrog kev tuag ntawm methemoglobinemia.
Nitroethane yog dab tsi?
Nitroethane yog cov organic compound uas muaj cov tshuaj formula C2H5NO2, uas zoo ib yam li nitromethane nyob rau hauv ntau txoj kev. Cov molar loj ntawm cov tshuaj no yog 75.067 g / mol. Nitroethane tshwm sim raws li ib tug oily kua ntawm tus qauv kub thiab siab tej yam kev mob. Txawm li cas los xij, ntshiab nitroethane tsis muaj xim thiab muaj ntxhiab tsw qab. Nws yog me ntsis dej-soluble, thiab nws muaj qhov melting tsawg heev (-90 degrees Celsius) thiab kub kub point (112 degrees Celsius).
Daim duab 02: Cov Qauv Tshuaj ntawm Nitroethane
Thaum xav txog kev npaj nitroethane, peb tuaj yeem tsim nws kev lag luam los ntawm kev kho propane nrog nitric acid nyob ib ncig ntawm 350-450 degrees Celsius. Qhov no yog ib qho tshuaj tiv thaiv exothermic. Nws muab 4 nitroalkanes tseem ceeb: nitromethane, nitroethane, 1-nitropropane, thiab 2-nitropropane. Tsis tas li ntawd, cov tshuaj tiv thaiv no suav nrog cov dawb radicals, suav nrog cov radical CH3CH2CH2O. Qhov no radical cov ntaub ntawv los ntawm hemolysis ntawm coj nitrite ester. Qhov no yog alkoxy radical uas raug rau C-C fragmentation tshwm sim. Qhov no piav qhia txog kev tsim cov khoom sib xyaw.
Muaj ntau yam tseem ceeb ntawm kev siv nitroethane, suav nrog kev hloov pauv mus rau lwm yam khoom thaum lub sij hawm Henry cov tshuaj tiv thaiv, condensation muab oxazoline, ua ib qho roj additive, thiab ua tus precursor rau foob pob ua ntxaij propellants, thiab lwm yam.
Qhov txawv ntawm Ethyl Nitrite thiab Nitroethane yog dab tsi?
Qhov sib txawv tseem ceeb ntawm ethyl nitrite thiab nitroethane yog tias nyob rau hauv ethyl nitrite, ib qho oxygen atom txuas rau carbon atom thaum lwm cov pa atom txuas rau nitrogen atom, hos nyob rau hauv nitroethane, ob qho tib si oxygen atoms raug khi rau. cov nitrogen atom. Tsis tas li ntawd, ethyl nitrite tshwm raws li cov xim tsis muaj xim rau cov kua daj, thaum nitroethane yog cov kua roj.
Cov duab hauv qab no nthuav tawm qhov sib txawv ntawm ethyl nitrite thiab nitroethane hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Ethyl Nitrite vs Nitroethane
Ethyl nitrite thiab nitroethane yog ob cov tshuaj sib xyaw nrog tib cov tshuaj formula. Tab sis qhov sib txawv tseem ceeb ntawm ethyl nitrite thiab nitroethane yog lawv cov qauv tshuaj; ethyl nitrite muaj ib qho oxygen atom txuas rau carbon atom thiab ib qho oxygen atom txuas rau nitrogen atom, tab sis nitroethane muaj ob qho tib si oxygen atoms bonded rau nitrogen atom.
