Taw qhia
Fluorobenzyl bromide yog ib qho organic compound. Nws yog xim tsis muaj xim rau daj ntseg daj nrog cov ntxhiab tsw muaj zog.
Fluorobenzyl bromide muaj ntau yam khoom tseem ceeb thiab siv. Nws yog ib qho tseem ceeb nruab nrab siv dav hauv thaj chaw ntawm cov organic synthesis. Fluorobenzyl bromide tuaj yeem qhia cov pab pawg ua haujlwm nrog cov tshuaj lom neeg tshwj xeeb rau hauv lub nplhaib uas muaj ntxhiab los ntawm kev hloov cov tshuaj tiv thaiv, thiab kuj tseem siv rau hauv kev npaj cov khoom sib xyaw ua haujlwm.
Ib txoj hauv kev zoo rau kev npaj ntawm fluorobenzyl bromide yog los ua benzyl bromide nrog anhydrous hydrofluoric acid. Hauv cov tshuaj tiv thaiv no, hydrofluoric acid ua raws li bromine atom thiab qhia txog fluorine atom.
Nws yog cov organic uas muaj qee yam toxicity. Tej zaum yuav ua rau khaus thiab puas rau ntawm daim tawv nqaij, qhov muag, thiab ua pa. Cov cuab yeej tiv thaiv tsim nyog xws li hnab looj tes, tsom iav, thiab lub ntsej muag tiv thaiv yuav tsum tau hnav thaum ua haujlwm. Yuav tsum tau zam lub vapors ntawm flubromide ntev kom tsis txhob muaj tshuaj lom. Yog tias koj tau ntsib nrog fluorobenzyl bromide los yog nws cov vapors, koj yuav tsum tam sim ntawd yaug nrog dej huv thiab nrhiav kev kho mob raws sij hawm. Thaum khaws cov fluorobenzyl bromide, nws yuav tsum muab tso rau hauv qhov hluav taws kub-resistant, zoo-ventilated thiab airtight thawv, kom deb ntawm ignition thiab lwm yam khoom siv hluav taws xob.
