Taw qhia
Nitrobenzyl bromide yog ib qho organic compound, thiab cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm nitrobenzyl bromide:
Zoo:
Nitrobenzyl bromide yog ib qho khoom nrog dawb crystals ntawm chav tsev kub. Nws muaj ib tug pungent tsw thiab muaj ib tug siab melting thiab boiling point. Lub compound yog insoluble nyob rau hauv dej thiab yooj yim soluble nyob rau hauv organic solvents xws li ethanol thiab ether.
Siv:
Nitrobenzyl bromide muaj ntau yam kev siv hauv kev lag luam tshuaj. Nws tuaj yeem siv los ua cov khoom siv raw rau cov organic synthesis cov tshuaj tiv thaiv, thiab tuaj yeem koom nrog kev hloov cov tshuaj tiv thaiv ntawm benzene nplhaib los tsim ntau yam sib txawv ntawm cov organic sib txuas.
Txoj kev:
Txoj kev npaj ntawm nitrobenzyl bromide feem ntau cuam tshuam nrog kev hloov cov tshuaj tiv thaiv ntawm benzene nplhaib. Ib txoj hauv kev npaj ntau yog siv cov tshuaj tiv thaiv ntawm sodium bromide (NaBr) thiab nitric acid (HNO3) los hloov bromine rau bromobenzene, uas tom qab ntawd ua rau cov nitrooxides (xws li nitrosobenzene lossis nitrosotoluene) los tsim nitrobenzyl bromide.
Cov ntaub ntawv kev nyab xeeb:
Nitrobenzyl bromide yog ib qho tshuaj lom neeg uas ua rau khaus thiab corrosive. Kev sib cuag ntawm daim tawv nqaij thiab ob lub qhov muag tuaj yeem ua rau khaus thiab mob, thiab nqus tau los yog noj ntau ntau tuaj yeem ua rau muaj kev puas tsuaj rau lub ntsws thiab plab hnyuv. Cov hnab looj tes tiv thaiv, tsom iav thiab qhov ncauj qhov ntswg yuav tsum tau hnav thaum siv nitrobenzyl bromide, thiab kev ua haujlwm yuav tsum tau ua nyob rau hauv qhov chaw muaj cua zoo. Tsis tas li ntawd, nws yuav tsum tau khaws cia kom deb ntawm qhov hluav taws kub thiab oxidizers kom tiv thaiv hluav taws thiab tawg. Cov txheej txheem kuaj kom raug thiab ntsuas kev nyab xeeb yuav tsum tau ua raws li thaum tuav cov khoom sib xyaw no.
