Taw qhia
1,1,1-Trifluoroacetone. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
1,1,1-trifluoroacetone yog cov kua nplaum uas muaj qhov ntsim thiab qab zib. Nws yog cov tshuaj lom neeg ruaj khov, tsis yooj yim decomposed los ntawm acids, alkalis lossis oxidants, thiab tsis yooj yim hydrolyzed. Nws muaj solubility zoo thiab soluble nyob rau hauv ntau yam organic solvents xws li cawv, ethers, thiab ketones.
Siv:
1,1,1-Trifluoroacetone muaj ntau yam kev siv hauv kev lag luam. Nws yog ib qho hnyav hnyav uas tuaj yeem siv rau hauv thaj chaw xws li txheej, tshuaj ntxuav, degreasers, thiab roj sealants. Nws tseem tuaj yeem siv los ua tus neeg sawv cev o rau polyurethane, polyester thiab PTFE, nrog rau cov yas yas thiab nplaim hluav taws rau cov txheej.
Txoj kev:
Kev npaj ntawm 1,1,1-trifluoroacetone feem ntau yog ua los ntawm cov tshuaj tiv thaiv fluorinated reagent nrog acetone. Ib txoj hauv kev yog siv ammonium bifluoride (NH4HF2) los yog hydrogen fluoride (HF) los teb nrog acetone nyob rau hauv lub xub ntiag ntawm ib tug catalyst los tsim 1,1,1-trifluoroacetone. Cov txheej txheem tshuaj tiv thaiv no yuav tsum tau ua raws li kev tswj hwm nruj vim tias hydrogen fluoride yog cov pa phem.
Cov ntaub ntawv kev nyab xeeb:
1,1,1-Trifluoroacetone yog cov kua nplaum uas tuaj yeem tawg thaum raug nplaim taws lossis kub kub. Nws muaj qhov taw tes qis qis thiab autoignition kub, thiab yuav tsum tau tuav thiab khaws cia kom zoo, kom deb ntawm qhov hluav taws kub thiab cov khoom kub. Cov cuab yeej tiv thaiv tsim nyog xws li looj tsom iav, hnab looj tes thiab khaub ncaws tiv thaiv yuav tsum hnav thaum siv. Nws yuav tsum tau ua kom paub tseeb tias yuav tsum tau ua haujlwm nyob rau hauv qhov chaw muaj cua zoo thiab tsis txhob nqus nws cov vapors vim nws tuaj yeem ua rau tib neeg lub cev puas tsuaj. Thaum ntsib daim tawv nqaij lossis qhov muag, yaug tam sim nrog dej ntau thiab nrhiav kev pab kho mob.
