Taw qhia
Pentafluoropropionic acid yog cov kua tsis muaj xim nrog cov ntxhiab tsw. Nws yog ib tug muaj zog acid uas reacts nrog dej los tsim hydrofluoric acid. Pentafluoropropionic acid yog ib tug muaj zog oxidizing tus neeg sawv cev uas reacts nrog ntau cov organic tshuaj thiab hlau. Nws decomposes ntawm qhov kub thiab txias thiab corrosive.
Pentafluoropropionic acid muaj ntau yam kev siv hauv kev lag luam tshuaj. Nws kuj tseem siv rau hauv kev npaj cov khoom siv polymer xws li polytetrafluoroethylene thiab polymerized perfluoropropylene. Pentafluoropropionic acid kuj yog siv los ua electroplating, xeb inhibitor thiab kho deg tus neeg saib xyuas.
Muaj ntau txoj hauv kev rau kev npaj ntawm pentafluoropropionic acid, ib qho ntawm feem ntau tau los ntawm cov tshuaj tiv thaiv ntawm boron trifluoride thiab hydrogen fluoride. Hydrogen fluoride roj tau dhau mus rau hauv kev daws ntawm boron trifluoride thiab reacted ntawm qhov kub thiab txias kom tau txais pentafluoropropionic acid thaum kawg.
Nws yog nruj nreem corrosive thiab irritating, ua rau kub hnyiab thiab khaus heev nyob rau hauv kev sib cuag nrog daim tawv nqaij los yog ob lub qhov muag. Cov cuab yeej tiv thaiv tus kheej xws li hnab looj tes tiv thaiv, tsom iav, thiab khaub ncaws tiv thaiv yuav tsum tau siv thaum ua haujlwm. Nws yuav tsum tau siv nyob rau hauv qhov chaw zoo-ventilated kom tsis txhob nqus nws vapors. Yog tias nqus tau, tau txais huab cua ntshiab tam sim ntawd thiab nrhiav kev kho mob.
