Ozonolysis yog oxidation ntawm unsaturated bonds nyob rau hauv cov organic tebchaw los ntawm ozone. Ozonolysis yog feem ntau siv los ntxuav alkenes kom tau ob yam khoom carbonyl. Ozone kuj reacts nrog alkynes thiab hydrazones.

Tsis tas li ntawd, piv txwv li ozonolysis yog dab tsi?

Ozonolysis yog cov tshuaj tiv thaiv organic uas tsis muaj kev sib txuas ntawm alkenes, alkynes, lossis azo tebchaw yog cleaved nrog ozone. Alkenes thiab alkynes tsim cov organic tebchaw uas muaj ntau yam carbon-carbon daim ntawv cog lus tau hloov los ntawm ib pawg carbonyl thaum azo tebchaw tsim nitrosamines.

Ib sab saum toj no, dab tsi tshwm sim hauv ozonolysis? Ozonolysis yog tus txheej txheem uas ozone (O3) reacts nrog alkenes (olefins) kom tawg ob daim ntawv cog lus thiab tsim ob pawg carbonyl. Ua raws li ib khub ntawm cov tshuaj txiab, cov roj reactive txiav ob daim ntawv cog lus thiab hloov nws nrog oxygen atoms, i. e., carbonyl pawg.

Ib tug kuj yuav nug, dab tsi yog qhov tseem ceeb ntawm ozonolysis?

Ozonolysis yog cov txheej txheem muaj peev xwm ua tau aldehydes, dialdehydes, carboxylic acids, dicarboxylic acids, cawv thiab dialcohols nyob ntawm seb cov quench reagent thov. Txawm li cas los xij, ozonolysis tuaj yeem siv rau lwm cov txheej txheem oxidative, xws li oxidation ntawm amines rau nitro pawg.

Dab tsi yog ozonolysis piav qhia ozonolysis nrog cov piv txwv tsim nyog?

Ozonolysis yog qhov cleavage ntawm alken los yog alkyne nrog ozone (O3). Cov txheej txheem tso cai rau carbon-carbon ob npaug los yog triple daim ntawv cog lus hloov los ntawm ob daim ntawv cog lus nrog oxygen. Cov tshuaj tiv thaiv no feem ntau siv los txheeb xyuas cov qauv ntawm cov tsis paub alkenes. los ntawm kev rhuav tshem lawv mus rau hauv me me, yooj yim dua daim ntawv txheeb xyuas.
