Mawu Oyamba

Pentafluoropropionic acid ndi madzi opanda mtundu okhala ndi fungo lamphamvu. Ndi asidi amphamvu omwe amachitira ndi madzi kupanga hydrofluoric acid. Pentafluoropropionic acid ndi amphamvu oxidizing wothandizila kuti amakumana ndi zinthu zambiri organic ndi zitsulo. Zimawola pakatentha kwambiri ndipo zimawononga.

 

Pentafluoropropionic acid imakhala ndi ntchito zambiri m'makampani opanga mankhwala. Amagwiritsidwanso ntchito pokonza zinthu za polima monga polytetrafluoroethylene ndi polymerized perfluoropropylene. Pentafluoropropionic acid imagwiritsidwanso ntchito ngati electroplating, inhibitor ya dzimbiri komanso wothandizira mankhwala.

 

Pali njira zingapo zopangira pentafluoropropionic acid, imodzi mwazomwe zimachitika ndi boron trifluoride ndi hydrogen fluoride. Mpweya wa haidrojeni wa fluoride umadutsa mu njira ya boron trifluoride ndipo amachitira pa kutentha koyenera kuti pamapeto pake apeze pentafluoropropionic acid.

Zimakhala zowononga kwambiri komanso zimakwiyitsa, zomwe zimayambitsa kutentha ndi kupsa mtima kwakukulu pokhudzana ndi khungu kapena maso. Zida zodzitetezera monga magolovesi odzitetezera, magalasi, ndi zovala zodzitetezera ziyenera kugwiritsidwa ntchito panthawi yogwira ntchito. Ayenera kugwiritsidwa ntchito pamalo olowera mpweya wabwino kuti asapume mpweya wake. Ngati mwakowetsedwa, pezani mpweya wabwino nthawi yomweyo ndikupita kuchipatala.
