Peroxides yog cov tshuaj uas muaj peroxy-OOO-. Nws tuaj yeem pom tau tias yog ib qho derivative ntawm hydrogen peroxide, uas muaj cov peroxide ions (O) hauv cov molecule. Peroxides muaj xws li hlau peroxides, hydrogen peroxide, Peroxy acid acid ntsev thiab Organic peroxides. Hlau peroxides tuaj yeem tsim los ntawm cov ntsiab lus ntawm pawg IA, IIA, IIIB, thiab IVB nyob rau hauv lub rooj zaum, nrog rau qee yam kev hloov pauv xws li tooj liab, nyiaj, thiab mercury.
Cov txheej txheem npaj muaj xws li:
① Cov hlau nquag (xws li sodium) hlawv hauv cov pa.
② Dissolve active hlau (xws li poov tshuaj) nyob rau hauv kua ammonia thiab qhia oxygen.
③ Hydrogen peroxide reacts nrog ntsev. Hlau peroxides yog cov muaj zog oxidizing tus neeg sawv cev uas tso tawm oxygen thaum cua sov thiab hnov mob nrog dilute acids los tsim hydrogen peroxide.
Kev Siv: Hlau peroxides yog siv rau hauv textile thiab ntawv kev lag luam ua cov tshuaj bleaching. Ib los yog ob lub hydrogens hauv hydrogen peroxide yog hloov los ntawm cov organic pawg, thiab cov ntsiab lus tau hu ua Organic peroxides, xws li peracetic acid thiab Cumene peroxide. Lawv muaj zog oxidizing zog dua li cov hlau peroxides thiab yog cov nplaim taws thiab tawg tawg uas tuaj yeem siv los ua cov tshuaj tua kab mob, tshuaj tua kab mob, thiab tshuaj dawb.
Cov khoom siv: hydrogen peroxide (hydrogen peroxide), Sodium peroxide, thiab lwm yam.
