Taw qhia
Fluorobenzyl chloride yog ib qho organic compound. Nws yog cov kua uas tsis muaj xim nrog lub zog pungent tsw. O-fluorobenzyl chloride muaj qhov ntom ntom, zoo solubility, thiab soluble hauv cawv thiab ether cov kuab tshuaj.
Nws muaj ntau yam kev ua ub no xws li cov kab mob bactericidal, insecticides thiab anti-stress, thiab tuaj yeem siv rau kev tiv thaiv qoob loo thiab kev tshawb fawb thiab kev loj hlob ntawm biopesticides.
Txoj kev npaj ntawm o-fluorobenzyl chloride tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm chlorotoluene thiab fluoromethane bromide. Txoj kev npaj tshwj xeeb yog raws li hauv qab no: qhov kev faib ua feem ntawm chlorotoluene thiab flumebromide massage yog ntxiv rau cov tshuaj tiv thaiv lub raj mis, cov tshuaj tiv thaiv hnyav thiab catalyst ntxiv, cov tshuaj tiv thaiv yog rhuab, thiab tom qab cov tshuaj tiv thaiv tiav, o-fluorobenzyl chloride khoom yog purified. los ntawm distillation.
Thaum siv o-fluorobenzyl chloride, yuav tsum tau them nyiaj rau nws txoj kev nyab xeeb. Nws yog ib qho organic solvent uas yog irritating thiab volatile. Ntev ntev raug rau huab cua thiab kev sib cuag ncaj qha nrog daim tawv nqaij thiab qhov muag yuav tsum zam tom qab raug o-fluchloride. Tsis txhob nqus nws cov vapors thiab siv cov kev tiv thaiv xws li iav tiv thaiv, hnab looj tes thiab qhov ncauj qhov ntswg yog tias tsim nyog.
Thaum lub sij hawm cia thiab kev thauj mus los ntawm o-fluorobenzyl chloride, yuav tsum tau them nyiaj mloog mus rau tiv thaiv nws los ntawm kev sib cuag nrog cov pa oxygen thiab tsis txhob muaj kub kub los tiv thaiv nws los ntawm spontaneous combustion los yog tawg. Kev siv thiab khaws cia ntawm o-fluorobenzyl chloride kom raug, nrog kev ceev faj txog kev nyab xeeb, tuaj yeem pab kom tsis txhob muaj xwm txheej thiab kev pheej hmoo ntawm kev noj qab haus huv.
