Mawu Oyamba
Ubwino:
Pentafluoropropionic anhydride ndi madzi achikasu otumbululuka komanso onunkhira. Izo sizisungunuka m'madzi kutentha kwa firiji, sungunuka mu zosungunulira organic monga Mowa, acetone, etc. Ndi madzi oyaka ndi kuyaka.
Gwiritsani ntchito:
Pentafluoropropionic anhydride imagwiritsidwa ntchito kwambiri muzochita za fluorination mu organic synthesis reaction ndipo imagwiritsidwa ntchito ngati m'malo mwa hydrofluoric acid.
Njira:
Njira yokonzekera pentafluoropropionic anhydride ndi yovuta kwambiri, ndipo njira yodziwika bwino ndikuchita fluoroethanol ndi bromoacetic asidi kupanga fluoroethyl acetate, ndiyeno deether kuti apeze pentafluoropropionic anhydride.
Zambiri Zachitetezo:
Pentafluoropropionic anhydride imakwiyitsa ndipo ingayambitse kupsa mtima kwa maso, kupuma ndi khungu pamene ikukoka, kumeza, kapena kukhudzana ndi khungu. Kukoka mpweya wa nthunzi yake kuyenera kupewedwa mukagwiritsidwa ntchito. Njira zodzitetezera ziyenera kuchitidwa, monga kuvala zovala zamaso zotetezera ndi magolovesi oyenerera, ndi kuonetsetsa kuti akugwiritsidwa ntchito pamalo opumira mpweya wabwino. Pochita zochitika za fluorination, momwe zimachitikira ziyenera kuyendetsedwa mosamalitsa kuti zipewe kupanga zinyalala zowopsa za fluoride.
