Taw qhia
Zoo:
Pentafluoropropionic anhydride yog cov xim tsis muaj xim rau daj daj daj nrog cov ntxhiab tsw. Nws yog insoluble nyob rau hauv dej ntawm chav tsev kub, soluble nyob rau hauv organic solvents xws li ethanol, acetone, thiab lwm yam. Nws yog ib tug flammable kua thiab yog flammable.
Siv:
Pentafluoropropionic anhydride yog dav siv nyob rau hauv fluorination cov tshuaj tiv thaiv nyob rau hauv cov organic synthesis cov tshuaj tiv thaiv thiab feem ntau yog siv los hloov cov hydrofluoric acid.
Txoj kev:
Txoj kev npaj ntawm pentafluoropropionic anhydride yog qhov nyuaj dua, thiab ib txoj hauv kev yog los ua fluoroethanol nrog bromoacetic acid los tsim fluoroethyl acetate, thiab tom qab ntawd deether kom tau pentafluoropropionic anhydride.
Cov ntaub ntawv kev nyab xeeb:
Pentafluoropropionic anhydride ua rau khaus thiab yuav ua rau khaus ntawm lub qhov muag, ua pa thiab tawv nqaij thaum nqus tau, noj, lossis sib cuag nrog daim tawv nqaij. Kev nqus pa ntawm nws cov vapors yuav tsum zam thaum siv lossis ua haujlwm. Yuav tsum muaj kev tiv thaiv kev nyab xeeb, xws li hnav cov looj tsom iav thiab hnab looj tes uas tsim nyog, thiab xyuas kom meej tias lawv tau siv nyob rau hauv qhov chaw muaj cua zoo. Thaum ua cov tshuaj fluorination, cov tshuaj tiv thaiv yuav tsum tau tswj nruj me ntsis kom tsis txhob muaj cov tshuaj fluoride pov tseg.
