Nhanganyaya
1,1,1-Trifluoroacetone. Iyi inotevera sumo kune chimiro chayo, kushandiswa, nzira yekugadzirira uye ruzivo rwekuchengetedza:
Hunhu:
1,1,1-trifluoroacetone imvura inopisa ine spicy uye kutapira kuravira. Yakagadzikana zvakanyanya mumakemikari, haisi nyore kuparara nemaasidhi, alkalis kana oxidants, uye haisi nyore hydrolyzed. Iyo ine yakanaka solubility uye inonyungudika mune zvakasiyana siyana zveorganic solvents senge alcohols, ethers, uye ketones.
Shandisa:
1,1,1-Trifluoroacetone ine huwandu hwakawanda hwekushandisa muindasitiri. Chinhu chakakosha chinonyungudutsa chinogona kushandiswa munzvimbo dzakadai semabhanditi, makuchenesa, degreasers, uye gasi sealants. Inogona zvakare kushandiswa seyakazvimba mumiriri we polyurethane, polyester uye PTFE, pamwe chete neplasticizer uye murazvo unodzoreredza majasi.
Nzira:
Kugadzirira kwe1,1,1-trifluoroacetone kunonyanya kuitwa nekuita kwe fluorinated reagent ine acetone. Nzira yakajairika ndeye kushandisa ammonium bifluoride (NH4HF2) kana hydrogen fluoride (HF) kuita neacetone pamberi pechigadzirwa chekugadzira 1,1,1-trifluoroacetone. Kuita uku kunofanirwa kuitwa pasi pehutongi hwakasimba nekuti hydrogen fluoride igasi rine muchetura.
Zvekuchengetedza
1,1,1-Trifluoroacetone imvura inopfuta inogona kuputika kana yaiswa mumurazvo wakavhurika kana kupisa kwakanyanya. Iyo ine yakaderera flash point uye autoignition tembiricha, uye inoda kubatwa nekuchengetwa nemazvo, kure nekubatidza uye zvinhu zvinopisa. Midziyo yekudzivirira yakakodzera yakadai semapfekero emaziso ekudzivirira, magirovhosi uye zvipfeko zvekudzivirira zvinofanirwa kupfekwa kana zvichishandiswa. Inofanirwa kuve nechokwadi kuti inoshanda munzvimbo ine mhepo inofefetera uye kudzivirira kupinza mhute yayo sezvo ichigona kukuvadza muviri wemunhu. Kana wasangana neganda kana maziso, sukurudza nekukurumidza nemvura yakawanda uye tsvaga rubatsiro rwekurapa.
