Phosphorous Pentoxide
Phosphorous Pentoxide
Cov ntaub ntawv Technical
1. Alias: phosphoric anhydride
2. Cov mis mos molecular: P2O5
3. Molecular hnyav: 141.94
· Kev faib tawm thiab tus lej txaus ntshai:
GB8.1 qeb 81063. Thawj txoj cai hlau: Qib 1 inorganic acid corrosive khoom, 91034, UN NO.: 1807. IMDG CODE 8198 nplooj, 8 pawg.
· siv:
Cov khoom siv raw rau phosphorus oxychloride thiab metaphosphoric acid, acrylates, surfactants, dehydrating agents, desiccants, antistatic agents, refining of Medicine and sugars, and analytical reagents.
· Lub cev thiab tshuaj muaj zog:
Nws feem ntau yog dawb, zoo heev crystalline hmoov.Qhov ceev yog 0.9g / cm3, thiab nws sublimates ntawm 300 ° C.Lub melting point yog 580-585 ° C.Lub vapor siab yog 133.3Pa (384 ° C).Thaum rhuab mus rau qhov kub siab dua, cov siv lead ua hloov mus rau hauv lub cev zoo li amorphous iav, uas yooj yim absorbs noo noo hauv huab cua.Nws dissolves nyob rau hauv dej thiab emits cua sov thiab pa taws dawb.
· Cov yam ntxwv txaus ntshai:
Tsis-combustible.Txawm li cas los xij, nws cuam tshuam nrog dej thiab cov organic teeb meem xws li ntoo, paj rwb lossis nyom, tso cua sov, uas tuaj yeem ua rau hlawv.Cov pa taws ntau thiab cua sov tuaj yeem tsim tau thaum nws ntsib dej, thiab nws yog me ntsis corrosive rau feem ntau cov hlau thaum nws ntsib cov dej noo.Kev khaus hauv zos muaj zog heev.Chav thiab plua plav tuaj yeem ua rau lub qhov muag, mucous, tawv nqaij thiab ua pa hnyav.Thiab nws corrodes daim tawv nqaij thiab mucous daim nyias nyias.Txawm tias cov plua plav nrog ib qho concentration ntawm 1 mg / m3 yog unbearable.
