Qhov sib txawv tseem ceeb ntawm hydrazine thiab carbohydrazide yog tias hydrazine muaj H2N-NH2 qauv whereas carbohydrazide muaj ob lub hydrazine molecules txuas rau ib lub chaw carbonyl carbonyl.
Hydrazine thiab carbohydrazide yog cov tshuaj sib xyaw uas muaj H2N-NH2 units. Ib chav tsev ntawm cov qauv tshuaj no yog hu ua hydrazine thaum carbohydrazide muaj ob ntawm cov qauv no txuas nrog lub chaw carbonyl carbon.
YHydrazine yog dab tsi?
Hydrazine yog ib qho inorganic compound uas muaj cov tshuaj formula N2H4. Peb tuaj yeem hu nws ua ib qho yooj yim pnictogen hydride, thiab nws yog cov kua tsis muaj xim thiab flammable uas muaj cov ntxhiab tsw ammonical. Cov tshuaj no yog tshuaj lom heev, thiab peb yuav tsum ua tib zoo saib xyuas cov tshuaj no. Nws toxicity qis dua yog tias nws siv hauv kev daws teeb meem, piv txwv li. hydrazine hydrate.
Daim duab 01: Hydrazine Hydrate
Hydrazine yog qhov tseem ceeb ua tus neeg sawv cev foaming, uas yog ib qho tseem ceeb hauv kev npaj cov foams polymer. Ntxiv mus, nws yog ib qho tseem ceeb raws li ib tug precursor rau polymerization catalysts, pharmaceuticals, thiab agrochemicals, raws li zoo raws li ib tug ntev lub sij hawm storable propellant rau hauv-chaw spacecraft propulsion.
Muaj ntau txoj hauv kev rau kev tsim cov hydrazine, suav nrog oxidation ntawm ammonia ntawm oxaziridines los ntawm peroxide, chlorine-based oxidation, thiab lwm yam. Thaum xav txog cov tshuaj tiv thaiv ntawm hydrazine, nws qhia tau hais tias acid-base cwj pwm qhov twg hydrazine tuaj yeem tsim ib qho kev xav ntawm hydrazine. monohydrate uas yog denser dua li daim ntawv anhydrous, thiab nws muaj cov yam ntxwv (alkali) uas piv nrog ammonia. Tsis tas li ntawd, hydrazine tuaj yeem ua rau cov tshuaj tiv thaiv redox vim tias nws tuaj yeem ua raws li kev txo qis, muab cov khoom lag luam uas feem ntau yog nitrogen thiab dej.
YCarbohydrazide yog dab tsi?
Carbohydrazide yog cov organic compound uas muaj cov tshuaj formula H4N2-C(=O)-N2H4. Cov khoom no tshwm sim li dawb, dej-soluble khoom uas undergoes decomposition thaum melting. Muaj ntau tus carbazides uas muaj ib lossis ntau pawg N-H hloov los ntawm lwm cov neeg hloov pauv.
Daim duab 02: Cov qauv ntawm Carbohydrazide Molecule
Peb tuaj yeem tsim cov tshuaj no los ntawm kev kho urea nrog hydrazine. Tsis tas li, peb tuaj yeem npaj cov tshuaj no los ntawm kev cuam tshuam ntawm lwm yam C1 precursors nrog hydrazine, suav nrog carbonate esters.
Carbohydrazide molecule yog ib qho tsis muaj polar molecule, thiab tag nrho cov chaw nitrogen hauv cov molecule no tsawg kawg yog pyramidal, uas qhia tau hais tias tsis muaj zog C-N pi bonding.
Thaum xav txog kev siv cov khoom sib xyaw no, nws muaj txiaj ntsig zoo li cov pa oxygen scrubber, precursor rau polymers, muaj txiaj ntsig zoo hauv kev yees duab ua kom ruaj khov, tseem ceeb hauv kev tsim cov mos txwv phom, stabilize xab npum, thiab lwm yam.
Qhov txawv ntawm Hydrazine thiab Carbohydrazide yog dab tsi?
Hydrazine thiab carbohydrazide yog nitrogen-muaj tshuaj lom neeg. Qhov sib txawv tseem ceeb ntawm hydrazine thiab carbohydrazide yog tias hydrazine muaj H2N-NH2 qauv thaum carbohydrazide muaj ob lub hydrazine molecules txuas rau ib lub chaw carbonyl carbon. Tsis tas li ntawd, peb tuaj yeem categorize hydrazine ua ib qho inorganic compound thiab carbohydrazide ua cov organic compound vim hydrazine tsis muaj carbon atoms nyob rau hauv nws cov molecules txawm carbohydrazide muaj ib tug carbonyl carbon centre.
Ntxiv mus, peb tuaj yeem tsim hydrazine siv oxidation ntawm ammonia ntawm oxaziridines los ntawm peroxide, chlorine-based oxidation, thiab lwm yam. thiab carbohydrazide los ntawm kev kho urea nrog hydrazine.
Hauv qab infographic qhia ntau cov ntsiab lus ntawm qhov sib txawv ntawm hydrazine thiab carbohydrazide hauv daim ntawv teev npe.
Summary – Hydrazine vs Carbohydrazide
Hydrazine thiab carbohydrazide yog nitrogen-muaj tshuaj lom neeg. Qhov sib txawv tseem ceeb ntawm hydrazine thiab carbohydrazide yog tias hydrazine muaj H2N-NH2 qauv thaum carbohydrazide muaj ob lub hydrazine molecules txuas rau ib lub chaw carbonyl carbon. Ntxiv mus, hydrazine tshwm sim ua kua tsis muaj xim thaum carbohydrazide tshwm sim raws li cov khoom siv dawb dawb.
