YHydrogen Peroxide vs Carbamide Peroxide
Hydrogen peroxide thiab carbamide peroxide yog siv rau cov dej num zoo sib xws vim tias ob qho tib si muaj hydrogen peroxide. Piv txwv li, ob qho tib si siv los ua cov tshuaj ntxuav hniav dawb. Txawm li cas los xij, seb puas yuav siv hydrogen peroxide lossis carbamide peroxide txawv raws li qhov xav tau.
Hydrogen Peroxide
Hydrogen peroxide yog daim ntawv yooj yim tshaj plaws ntawm peroxide, uas txhais tau tias yog H 2O2 Nws yog cov kua ntshiab nrog lub hau. point 150 oC. Nws yog miscible tag nrho nrog dej, txawm li cas los xij, tuaj yeem sib cais tag nrho los ntawm distillation vim tias nws cov ntsiab lus kub yog siab dua li cov dej. Hydrogen peroxide yog ib qho muaj zog oxidizing thiab txo tus neeg sawv cev. Hydrogen peroxide yog nonlinear, non-planar molecule. Nws muaj cov qauv qhib phau ntawv.
Peroxides yog tsim los ntawm cov khoom lag luam ntawm ntau yam tshuaj tiv thaiv lossis ua ib qho nruab nrab. Hom kev tshwm sim no tshwm sim hauv peb lub cev ib yam nkaus. Peroxide muaj cov tshuaj lom hauv peb lub hlwb. Yog li ntawd, lawv yuav tsum tau neutralized sai li sai tau thaum lawv tsim. Peb lub hlwb muaj ib tug tshwj xeeb mechanism rau qhov ntawd. Muaj ib qho organelle hu ua peroxisomes hauv peb cov hlwb, uas muaj cov enzyme catalase. Qhov no enzyme catalyses lub decomposition ntawm hydrogen peroxide rau hauv dej thiab oxygen, yog li ua ib tug detoxification muaj nuj nqi.
Hydrogen peroxide muaj cov khoom phom sij, xws li decomposition rau oxygen thiab dej nrog evolution ntawm tshav kub, los yog decomposes vim muaj kab mob los yog sib cuag nrog active nto. Vim yog tsim cov pa oxygen, siab nce hauv cov ntim thiab nws kuj tuaj yeem tsim cov khoom tawg. Kev ua kom dawb huv ntawm hydrogen peroxide yog vim oxidation thiab tso tawm oxygen. Cov pa oxygen no yuav ua rau cov xim muaj xim, ua kom tsis muaj xim.
H2O2 → H2O + O
O + xim teeb meem → C olorless matter
Lwm yam tsis yog tshuaj dawb, H2O2 is siv cov oxidant rau foob pob hluav taws roj, tsim cov epoxides, tshuaj thiab zaub mov Cov khoom lag luam, raws li cov tshuaj tua kab mob, thiab lwm yam. Hydrogen peroxide yog khaws cia rau hauv paraffin wax coated iav, yas los yog Teflon fwj.
YCarbamide Peroxide
Carbamide peroxide yog ib qho ntxiv ntawm hydrogen peroxide thiab urea. Qhov no tseem hu ua urea peroxide, urea hydrogen peroxide, thiab percarbamide. Cov mis molecular ntawm carbamide peroxide tuaj yeem muab tau raws li CH6N2O3. Nov yog cov khoom siv dawb dawb nrog cov molar loj 94.07 g mol−1 Thaum cov khoom yaj hauv dej nws tso tawm hydrogen peroxide.
Carbamide peroxide yog oxidizer. Carbamide peroxide yog tsim los ntawm dissolving urea nyob rau hauv hydrogen peroxide thiab ces crystallizing nws. Raws li oxidizer, nws yog siv rau hauv ntau daim ntawv thov. Carbamide peroxide yog siv los ua cov hniav ntxuav hniav dawb. Vim yog cov hydrogen peroxide, nws kuj tuaj yeem siv los ua cov tshuaj bleaching thiab tshuaj tua kab mob. Yog li qhov no yog qhov tseem ceeb hauv kev lag luam tshuaj pleev ib ce thiab tshuaj. Txij li thaum qhov no tso tawm hydrogen peroxide thaum tawg, carbamide peroxide kuj yog siv los hloov cov hydrogen peroxide hauv chav kuaj. Txawm li cas los xij, thaum muaj ntau dua ntawm carbamide peroxide tuaj yeem ua rau corrosive thiab tuaj yeem ua rau tawv nqaij, qhov muag thiab ua pa ua pa. Yog li peb yuav tsum ceev faj thaum tuav cov tshuaj no.
Qhov txawv ntawm Hydrogen Peroxide thiab Carbamide Peroxide yog dab tsi?
• Carbamide peroxide muaj hydrogen peroxide hauv nws txuas nrog urea.
• Thaum yaj, carbamide peroxide tso tawm hydrogen peroxide.
• Hydrogen peroxide yog qhov nrawm dua thiab muaj zog oxidizer dua li carbamide peroxide.
Txij li thaum • tso tawm hydrogen peroxide los ntawm carbamide peroxide qeeb dua thiab txwv, nws yog cov hniav ntxuav hniav zoo dua.
• Carbamide peroxide ruaj khov dua li hydrogen peroxide.
