Taw qhia

1,4-Bis (trifluoromethyl) benzene yog cov organic compound, tseem hu ua 1,4-bis (trifluoromethyl) benzene. Cov hauv qab no yog ib qho kev qhia txog qee yam ntawm cov khoom siv, kev siv, kev npaj, thiab cov ntaub ntawv kev nyab xeeb:

Cov khoom siv: 1,4-Bis (trifluoromethyl) benzene yog cov kua tsis muaj xim uas muaj ntxhiab tsw zoo ntawm chav tsev kub.

 

Siv: 1,4-Bis (trifluoromethyl) benzene yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis. Nws cov khoom tshwj xeeb tshuaj kuj tuaj yeem siv los ua catalysts thiab ligands.

 

Txoj kev npaj: 1,4-bis (trifluoromethyl) benzene tuaj yeem nitrified los ntawm benzene kom tau nitrobenzene, thiab tom qab ntawd los ntawm nitroso txo-trifluoromethylation cov tshuaj tiv thaiv kom tau txais cov khoom lag luam.

 

Cov ntaub ntawv kev nyab xeeb: 1,4-bis (trifluoromethyl) benzene yog qhov ruaj khov nyob rau hauv cov xwm txheej dav dav, tab sis nws yuav tsum tsis txhob sib cuag nrog cov oxidants muaj zog thiab muaj zog alkalis. Nws tuaj yeem ua rau lub qhov muag, tawv nqaij, thiab ua pa ua pa thiab yuav tsum tsis txhob nqus los yog sib cuag. Thaum siv lossis khaws cia, yuav tsum muaj kev tiv thaiv tsim nyog, xws li hnav hnab looj tes thiab tsom iav. Nyob rau hauv rooj plaub ntawm kev sib chwv los yog kev tsis sib haum xeeb, nrhiav kev kho mob tam sim ntawd.
