Taw qhia
Nws yog ib yam kua uas tsis muaj xim nrog ib tug peculiar cawv tsw. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 4,4,4-trifluorobutanol:
Zoo:
4,4,4-Trifluorobutanol yog ib tug polar compound uas yog soluble nyob rau hauv polar solvents xws li dej, cawv, thiab ethers.
4,4,4-Trifluorobutanol muaj kev txhawb zog ntawm cov nplaim taws thiab ua rau combustion.
Lub compound yog ruaj khov nyob rau hauv cov huab cua, tab sis tuaj yeem decompose los tsim cov roj fluoride lom vim raug tshav kub los yog hluav taws kub.
Siv:
Nws kuj yog siv los ua cov kuab tshuaj thiab lub cev qhuav dej, thiab tshwj xeeb tshaj yog tsim nyog rau kev tshem tawm thiab ntxuav cov txheej txheem ntawm qee yam tshuaj bioactive.
Txoj kev:
Txoj kev npaj ntawm 4,4,4-trifluorobutanol feem ntau suav nrog cov kauj ruam hauv qab no:
1,1,1-trifluoroethane yog reacted nrog sodium hydroxide (NaOH) ntawm qhov tsim nyog kub thiab siab los tsim 4,4,4-trifluorobutanol.
Cov ntaub ntawv kev nyab xeeb:
4,4,4-Trifluorobutanol yog cov kua ua kua thiab yuav tsum tau siv thiab khaws cia yam tsis muaj hluav taws kub thiab kub.
Tsis txhob sib cuag nrog daim tawv nqaij, qhov muag, thiab ua pa ib ntsuj av los tiv thaiv kev khaus thiab kev puas tsuaj.
Kev ceev faj tsim nyog yuav tsum tau siv thaum tuav, suav nrog kev hnav cov hnab looj tes tiv thaiv, tsom iav, thiab cov cuab yeej tiv thaiv ua pa.
Nyob rau hauv qhov xwm txheej ntawm cov pa xau, kev ntsuas tsim nyog yuav tsum tau ua sai sai los kho, cais thiab ntxuav kom tsis txhob muaj kuab paug ib puag ncig thiab raug mob ntawm tus kheej.
Thaum lub sijhawm khaws cia thiab pov tseg, cov kev cai thiab cov txheej txheem kev nyab xeeb yuav tsum tau ua raws.
