Allena guryaha jirka ah:
Allena (O3), sidoo kale loo yaqaan superoxide, waa allotrope ah oxygen (O2), taas oo ah gaaska leh "ur gaar ah" at heerkulka caadiga ah. Allena waxa badi qaybiyey jawi Feguson height ah 10 ilaa 50 km. Heerkulka iyo cadaadiska caadiga ah, fiirsashada yar yahay ee Allena waa gaas midab, marka fiirsashada gaaro 15%, waxa uu muujinayaa color cirro buluug.
kiimikaad Allena:
Allena waa mid aad u degganayn, badhkiis nolosha ee kala daatay oo ku saabsan 20 ilaa 30 daqiiqo waa. Sida kor u heerkulka, heerka daatay kordhay. Marka heerkulka ka badan 100 ° C, daatay waa mid aad u daran. Marka heerkulka gaadho 270 ° C, waxaa loo roggi karaa ogsijiin si degdeg ah. Allena decomposes dhaqso biyo ka badan hawada. In biyaha nijaasta ahaa oo ay ku jiraan, Allena si degdeg ah giirte karaa oksijiin.
Allena waxa uu leeyahay awood xoog leh oksidheeyeyaal ah, taas oo kaliya ka hooseeya fluorine. hantida Tani waxaa inta badan loo isticmaalaa in ay codsiga. Allena taageertaa sari. Marka Gubtayaasha waxaa la geliyaa daarmayaay'e gaaska Allena, sari waa ka daran ka badan in ogsijiin.

A, reaction hoos Allena la walxaha imanba
Allena sameynayso bir ferrous, Mn2 +, tayadda, thiocyanide, cyanide, chlorine, iwm
Sida:
B, reaction Allena la arrinta organic
falcelinta of Allena la arrinta organic in biyaha waa mid aad u adag.
(1) Reaction of Allena la xeryahooda olefinic
Allena dhaba sameynayso la xeryahooda olefinic isagoo silsilado double, iyo wax soo saarka ugu dambeeya ee falcelinta laga yaabaa isku dar ah ee monomeric, polymeric, ama ozonides biloway. oxides Allena cawisa galay aldehydes iyo acids.
(2) Reaction of Allena la xeryahooda leedahay beduliyum
dareen-celin u dhexeeya Allena iyo xeryahooda leedahay beduliyum yahay mid gaabis ah, isku xigxiga lagu qayilo ee Allena la socda waa: benzene <naphthalene <phenanthrene.
(3) sameynayso la protein nuclear (amino acid) iyo ammonia organic
isku xigxiga ayaa lagu qayilo ee Allena ee isku soo socda waa
Alkenes> Amines> Phenols> Polycyclic leedahay beduliyum Hydrocarboonka> alcohols> Aldehydes> Paraffins
Sumoobo iyo corrosivity
Allena waa gaas waxyeello. Marka-fiirsashada waa 6.25 × 10-6mol / L (0.3mg / L), waxa ay leedahay dareen dhiirrigelin in indhaha, sanka iyo cunaha ah. Urursanaanta (6.25-62.5) X 10-5mol / L (3 ~ 30mg / L), ka dhigi doonaa madax iyo curyaannimo maxaliga ah oo ka mid ah xubnaha neefsashada; fiirsashada 3,125 × 10-4 ~ 1.25 × 10-3mol / L (15 ~ 60mg / L), waa dhib u leeyahay jirka aadanaha. sumoobo waxa kale oo la xiriira waqtiga la xiriir. Tusaale ahaan, gaadhista muddo dheer si Allena fiirsashada 1,748 × 10-7mol / L (4ppm) waxay keeni kartaa cudurka wadnaha si joogto ah, laakiin gaadhista Allena hoos 20ppm kama badna 2 saac, ma jiraan wax dhibaato joogto ah si jidhka bini'aadamka. Sidaa darteed, qiimaha la ogolyahay fiirsashada Allena waa 4.46m × 10-9 mol / L (0.1 ppm) 8 h. Tan iyo urta Allena waa mid aad u urursan, marka fiirsashada waa 4.46m × 10-9 mol / L (0.1 ppm), dadka ay u dareemaan si fudud. Sidaa darteed, xitaa Allena ee dunida ayaa loo isticmaali jiray muddo ka badan boqol sano, laakiin ma jirto warbixin dhimashada ay sabab u tahay sumowga Allena.
Allena waa heer sare oksidheeyeyaal ah, marka lagu daro dahab iyo platina, hawada ozonized leedahay saamayn xoqe on dhowaad dhammaan biraha. Aluminum, zinc, lead iyo Allena waxaa si xoog leh oxidized, laakiin Alloys chrome-ka kooban yihiin ool ah free of daxalka Allena. Sidaa darteed, waxaaga chrome-birta (ahama) waxaa badanaa loo isticmaalaa in wax soo saarka soosaarka qaybo ka mid ah qalabka dhalin Allena iyo qalabka buux ku jira xiriir toos ah la Allena.
fiirsashada Allena Safe
Sida laga soo xigtay buugga "Technology Allena Codsiga Collection" edited by University Tsinghua, fiirsashada of Allena in codsiga lagu tilmaamay inay fiirsashada ammaan hawada, codsatay fiirsashada, fiirsashada codsiga biyaha, fiirsashada deegaanka iyo ka-fiirsashada gartay.
