Zojambula zopangira phosphoros oxychloric ndi metaphshosphororic acid, ma acrylate
Zanyama ndi mankhwala:
Nthawi zambiri imakhala yoyera, yoyera kwambiri ya masikono. Kuchulukitsa ndi 0,9g / cm3, ndipo kumakhala kokwirira kwa 300 ° C. Malo osungunuka ndi 580-585 ° C. Kupsinjika kwa nthunzi ndi 133.3pa (384 ° C). Akatenthetsedwa kumtunda kwambiri, makristalo amasintha kukhala thupi lamorphous ngati magalasi, omwe amamwa chinyezi mosavuta mlengalenga. Imasungunuka m'madzi ndipo imapereka utsi wotentha ndi oyera.
Mikhalidwe:
Zosatheka. Komabe, imagwira mwamphamvu kwambiri ndi madzi ndi zinthu zachilengedwe monga nkhuni, thonje kapena udzu, kumasula kutentha, komwe kumayambitsa kuyaka. Utsi wina ndi kutentha ukhoza kupangidwa pomwe umakumana ndi madzi, ndipo ndi pang'ono pang'ono pazitsulo zambiri pomwe zimakumana ndi chinyezi. Kukhumudwa kwanuko ndikolimba kwambiri. Steam ndi Fumbi limatha kupweteka kwambiri, mucous nembanemba, khungu ndi kupuma. Ndipo imang'amba khungu ndi mucous nembanemba. Ngakhale fumbi ndi ndende ya 1 mg / m3 sinathe.
