Qhov sib txawv tseem ceeb ntawm epoxidation thiab oxidation yog tias epoxidation yog hais txog kev hloov pauv ntawm ob pawg carbonated rau hauv pawg epoxide, qhov oxidation yog hais txog kev sib xyaw ntawm oxygen nrog cov khoom.
Epoxidation thiab oxidation yog cov ntsiab lus hauv cov organic synthesis. Epoxidation tuaj yeem piav qhia raws li daim ntawv tshwj xeeb ntawm oxidation uas tshwj xeeb muab cov cyclic oxide compound / epoxide compound.
YEpoxidation yog dab tsi?
Epoxidation yog cov txheej txheem tshuaj uas tuaj yeem hloov pauv C-C chemical bond rau hauv daim ntawv cog lus epoxide. Ib qho epoxide yog cyclic ether muaj ob qho tib si carbon atoms ntawm ob daim ntawv cog lus khi rau tib lub atom oxygen. Cov tshuaj no tseem hu ua oxiranes.
Daim duab 01: Cov qauv dav dav ntawm Epoxide
Peb tuaj yeem tsim cov epoxide los ntawm cov tshuaj tiv thaiv ntawm peracids thiab ob-bonded carbon atoms. Hauv peracids, muaj cov pa oxygen-oxygen daim ntawv cog lus uas tsis tsuas yog qaug zog tab sis kuj muaj cov ntawv cog lus polarized. Yog li ntawd, pawg acyloxy hauv qhov sib xyaw no muaj cov nqi tsis zoo, thiab pawg hydroxyl muaj cov nqi zoo. Txawm li cas los xij, qhov nruab nrab dipolar tsis zoo li tsim, yog li cov kws tshawb fawb ntseeg tias qhov tshuaj tiv thaiv no tshwm sim hauv ib kauj ruam dhau los ntawm kev hloov pauv uas suav nrog tag nrho cov tshuaj sib txuas thiab kev sib koom ua ke sib koom ua ke tib lub sijhawm.
Oxidation yog dab tsi?
Oxidation yog cov txheej txheem ntawm oxidation naj npawb ntawm cov tshuaj lom neeg. Txawm li cas los xij, muaj peb lub ntsiab lus txawv rau lo lus no; Qhov sib ntxiv ntawm oxygen, tshem tawm hydrogen, lossis poob ntawm electrons txhais tau tias oxidation. Tab sis tag nrho cov lus txhais no muaj kev zam rau lub sijhawm sib txawv. Yog li, peb siv cov lus txhais saum toj no ua ib qho kev txhais dav dav rau txhua lub sijhawm.
Daim duab 02: Txo-Oxidation Reaction
Oxidation yog hom tshuaj tiv thaiv redox. Ib qho tshuaj tiv thaiv redox tseem ceeb muaj ob qho kev sib piv: cov tshuaj tiv thaiv oxidation thiab txo cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv no ib txwm koom nrog kev hloov hluav taws xob ntawm ob hom tshuaj. Tsis tas li ntawd, hom tshuaj uas raug oxidation yuav ib txwm tso tawm electrons, thaum cov tshuaj uas txo qis yuav ib txwm tau txais cov electrons. Yog li ntawd, tso tawm electrons ua rau ntau protons uas tsis muaj electrons los neutralize lawv cov nqi. Yog li, kev tshem tawm hluav taws xob yuav ua rau oxidation tus naj npawb ntawm cov tshuaj lom neeg.
Dab tsi yog qhov zoo sib xws ntawm Epoxidation thiab Oxidation?
- Epoxidation thiab oxidation yog hom oxidation cov tshuaj tiv thaiv uas koom nrog ntxiv cov pa atoms rau cov organic tebchaw.
- Ob qhov kev cuam tshuam yog qhov tseem ceeb hauv cov tshuaj tiv thaiv kev sib xyaw ua ke.
- Cov tshuaj tiv thaiv no muab hom oxide compounds ua cov khoom kawg.
Qhov txawv ntawm Epoxidation thiab Oxidation yog dab tsi?
Epoxidation thiab oxidation yog cov ntsiab lus hauv cov organic synthesis. Qhov sib txawv tseem ceeb ntawm epoxidation thiab oxidation yog tias epoxidation yog hais txog kev hloov pauv ntawm ob pawg sib koom ua ke rau hauv pawg epoxide, thaum oxidation yog hais txog kev sib xyaw ntawm oxygen nrog cov khoom. Yog li, cov tshuaj tiv thaiv epoxidation muab ib qho epoxide ua qhov khoom kawg ntawm cov tshuaj tiv thaiv, uas yog ib pawg cyclic uas muaj cov pa atom thiab ob lub atoms carbon. Ntawm qhov tod tes, oxidation muab cov oxide compound ua cov khoom kawg, uas muaj cov pa roj carbon monoxide uas tsis yog-cyclic.
Cov infographic hauv qab no nthuav tawm qhov sib txawv ntawm epoxidation thiab oxidation hauv daim ntawv tabular.
Summary – Epoxidation vs Oxidation
Epoxidation thiab oxidation yog cov ntsiab lus hauv cov organic synthesis. Qhov sib txawv tseem ceeb ntawm epoxidation thiab oxidation yog tias epoxidation yog hais txog kev hloov dua siab tshiab ntawm ob pawg pa roj carbon monoxide rau hauv pawg epoxide, qhov oxidation yog hais txog kev sib xyaw ntawm oxygen nrog cov khoom.
