Taw qhia
4-Fluorobenzyl cyanobenzyl yog cov organic compound.
Solubility: Nws yog soluble hauv cov organic solvents xws li ethanol, dimethylformamide thiab acetone.
Cov ntxhiab tsw: 4-Fluorobenzyl cyanobenzyl muaj cov ntxhiab tsw tshwj xeeb benzene.
Siv:
4-Fluorobenzyl cyanide yog dav siv nyob rau hauv cov organic synthesis tshuaj raws li ib tug tseem ceeb nruab nrab.
Txoj kev:
Muaj ntau txoj hauv kev los npaj 4-fluorobenzyl cyanide. Ib txoj kev siv feem ntau yog tau los ntawm cov tshuaj tiv thaiv ntawm benzonitrile nrog hydrofluoric acid. Tsis tas li ntawd, benzyl cawv kuj tuaj yeem cuam tshuam nrog thionyl chloride ua ntej, thiab tom qab ntawd tau hnov qab nrog cov tshuaj fluoride thaum kawg tau txais 4-fluorobenzylbenzyl.
Cov ntaub ntawv kev nyab xeeb:
4-Fluorobenzyl cyanobenzyl ua rau khaus thiab tuaj yeem ua rau khaus thiab khaus ntawm daim tawv nqaij, qhov muag, thiab cov mucous membranes. Cov hnab looj tes tiv thaiv, tsom iav thiab cov khaub ncaws tiv thaiv yuav tsum hnav thaum ua haujlwm.
Tsis txhob nqus cov pa ntawm 4-fluorobenzyl cyanide thiab sim ua haujlwm hauv qhov chaw uas muaj cua zoo.
Thaum siv thiab khaws cia 4-fluorobenzyoxybenzyl, nws yuav tsum tau khaws cia kom deb ntawm qhov hluav taws kub thiab qhov hluav taws kub uas tshwm sim los ntawm qhov kub thiab txias.
4-Fluorobenzyl cyanide yog cov kuab tshuaj organic, thiab yuav tsum tau saib xyuas kom tsis txhob muaj qhov nkag mus rau hauv ib puag ncig kom tsis txhob muaj kuab paug rau tib neeg lub cev thiab ib puag ncig.
