Mawu Oyamba
1, 1, 1-Trifluoroacetone. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
1,1,1-trifluoroacetone ndi madzi oyaka moto okhala ndi zokometsera komanso kukoma kokoma. Ndiwokhazikika pamankhwala, sawonongeka mosavuta ndi zidulo, ma alkalis kapena oxidants, ndipo samasungunuka mosavuta. Ili ndi kusungunuka kwabwino ndipo imasungunuka m'mitundu yosiyanasiyana ya zosungunulira monga ma alcohols, ethers, ndi ketones.
Gwiritsani ntchito:
1,1,1-Trifluoroacetone ili ndi ntchito zosiyanasiyana m'makampani. Ndiwosungunulira wofunikira womwe ungagwiritsidwe ntchito m'malo monga zokutira, zotsukira, zochotsera mafuta, ndi zosindikizira gasi. Itha kugwiritsidwanso ntchito ngati chotupa chotupa cha polyurethane, poliyesitala ndi PTFE, komanso pulasitiki ndi chotchingira chamoto cha zokutira.
Njira:
Kukonzekera kwa 1,1,1-trifluoroacetone kumapangidwa makamaka ndi zomwe fluorinated reagent ndi acetone. Njira yodziwika bwino ndiyo kugwiritsa ntchito ammonium bifluoride (NH4HF2) kapena hydrogen fluoride (HF) kuti achite ndi acetone pamaso pa chothandizira kupanga 1,1,1-trifluoroacetone. Izi ziyenera kuchitika mosamalitsa chifukwa hydrogen fluoride ndi mpweya wapoizoni.
Zambiri Zachitetezo:
1,1,1-Trifluoroacetone ndi madzi oyaka omwe amatha kuphulika akakhala pamoto wotseguka kapena kutentha kwambiri. Ili ndi malo otsika komanso kutentha kwa autoignition, ndipo imayenera kugwiridwa ndikusungidwa bwino, kutali ndi kuyatsa ndi zinthu zotentha. Zida zodzitetezera zoyenera monga zovala zoteteza maso, magolovesi ndi zovala zodzitetezera ziyenera kuvalidwa zikagwiritsidwa ntchito. Iyenera kuwonetseredwa kuti ikugwira ntchito pamalo olowera mpweya wabwino ndikupewa kutulutsa nthunzi yake chifukwa imatha kuwononga thupi la munthu. Mukakhudza khungu kapena maso, muzimutsuka mwamsanga ndi madzi ambiri ndikupempha thandizo lachipatala.
