Phosphorous pentoxide
Phosphorous pentoxide
Cov Ntawv Qhia Cov Ntawv
1. Alias: Phosphoric AnhyDride
2. Molecular Cov Qauv: P2O5
3. Molecular Luj: 141.94
· Cov kev cai tswj txaus phom sij ntawm kev faib tawm thiab tus lej:
GB8.1 Qeb 81063. Thawj cov kab hlau: qib 1 inorganic acid corrosive khoom, 91034, un. IMDG code 8198 nplooj ntawv, 8 pawg.
· Siv tau:
Cov ntaub ntawv raw rau phosphorus oxychloride thiab cov tshuaj tiv thaiv acrylates, desiccants, kho cov tshuaj thiab cov suab thaj, thiab cov tshuaj hiav txwv tsis zoo.
· Kev siv tshuaj thiab tshuaj lom neeg:
Nws yog feem ntau yog dawb, siab deliquescent crystalline hmoov. Qhov ceev ceev yog 0.9g / CM3, thiab nws sublimates ntawm 300 ° C. Lub ntsiab lus melting yog 580-585 ° C. Lub vapor siab yog 133.3pa (384 ° C). Thaum rhuab rau ib qho kub siab dua nyob rau hauv siab, lub crystal hloov mus rau lub khob amorphous zoo li, uas yooj yim nqus noo hauv huab cua. Nws yaj nyob rau hauv dej thiab emits thaum tshav kub kub thiab dawb haus luam yeeb.
· Cov yam ntxwv:
Tsis-sib ceg. Txawm li cas los xij, nws rov qab ua txhaum nrog dej thiab cov organic muaj teeb meem xws li ntoo, paj rwb lossis nyom, uas tuaj yeem ua kom sov, uas tuaj yeem ua kom sov. Ntau cov pa luam yeeb thiab cua sov tuaj yeem tsim tawm thaum nws ntsib dej, thiab nws yog me ntsis corrosive rau feem ntau cov hlau thaum nws ua tau ya raws. Kev voos hauv zos muaj zog heev. Chav thiab cov plua plav tuaj yeem ua rau muaj khaus ob lub qhov muag, cov plaub hau ib ce, tawv nqaij thiab ua pa. Thiab nws corrodes ntawm daim tawv nqaij thiab cov tawv nqaij ua haujlwm. Txawm plua plav muaj plua plav ntawm 1 mg / m3 yog unbearable.
