Ozone senama:
Ozone (O3), tsejoang hape e le superoxide, ke allotrope oksijene (O2), e ke khase e nang le "monko o khethehileng" ho mocheso tloaelehileng. Ozone e haholo-holo a aba ka sepakapaka stratospheric ka ba bolelele ba 10 ho isa ho 50 km SE. Ha mocheso ho tloaelehile le ho hatelloa ke tlaase mahloriso tsa ozone ke khase colorless, ha mahloriso fihla 15%, ho bontša ka palo 'mala ba lehodimo.
thepa ozone lik'hemik'hale:
Ozone ke sa tsitsang haholo, le halofo ea bophelo ba li bole kapele e ka bang 20 ho metsotso e 30. E le eketseha mocheso, ho eketseha li bole kapele sekhahla. Ha mocheso feta 100 ° C, e li bole kapele e le matla haholo haholo. Ha mocheso fihla 270 ° C, e ka fetoloa oksijene hang-hang. Ozone bola kapele ka metsi ho feta moeeng. Ka nang manya metsi, ozone ka potlako bole ka oksijene.
Ozone na le matla oxidizing bokhoni, e ka tlaase feela ho feta fluorine. thepa ena e haholo-holo sebelisoa ka kopo ea eona. Ozone tshehetsa combustion e. Ha combustibles di kenngoa ozone khase ambient, combustion e ke e matla ho feta oksijene.

Toxicity le corrosivity
Ozone ke khase e kotsi. Ha mahloriso ke 6,25 × 10-6mol / L (0.3mg / L), e na le hlasimollang boikutlo bo mahlong, nko le qoqotho. Mahloriso (6.25-62.5) Tiket 10-5mol / L (3 ~ 30mg / L), o tla etsa hore hlooho le shoele litho ea moo ea makala le ho hema; mahloriso 3,125 × 10-4 ~ 1,25 × 10-3mol / L (15 ~ 60mg / L), e ke kotsi ho 'mele oa motho. toxicity o boetse o amana le nako o ikopanye le. Ka mohlala, nako e telele ho pepesehela ozone mahloriso 1,748 × 10-7mol / L (4ppm) ho ka etsa hore lefu ka ho sa feleng pelo, empa ho pepesehela ozone tlase 20ppm ha feta 2h, ho na le ho na kotsi ka ho sa feleng ho 'mele oa motho. Ka hona, le boleng lumelleha tsa mahloriso ozone ke 4,46 × 10-9 Mol / L (0,1 ppm) 8 H. Ho tloha ka monko oa ozone e concentrated haholo, ha mahloriso a 4,46 × 10-9 Mol / L (0,1 ppm), batho ba nka ho habonolo. Ka hona, esita le ozone ka lefatše e 'nile ea sebelisoa bakeng sa tse fetang lekholo lilemo tse, empa ho na le ho na tlaleho ea lefu ka lebaka la ho ozone chefo.
Ozone ke haholo oxidizing, ho phaella ho khauta le polatinamo, ozonized moea e na le phello e senyang ka hoo e ka bang tsohle tšepe. Aluminium, zinki, etella pele le ozone ba matla oxidized, empa google chrome-e nang le lits'epe tse kopantsoeng ke haholo e sa lefelloeng ea ozone ts'enyeho. Ka hona, google chrome ea tšepe e motsoako (celik) e atisa ho sebelisa tlhahiso ho proizvodnje likarolo tsa ozone fehla motlakase thepa le tlatsang thepa tse ka ho toba le ozone.
