Taw qhia
Benzyl bromide yog ib qho organic compound nrog cov tshuaj formula C7H7Br. Nov yog qee cov ntaub ntawv hais txog cov khoom, kev siv, kev npaj thiab kev nyab xeeb ntawm benzyl bromide:
Zoo:
Benzyl bromide yog cov kua xim tsis muaj xim nrog cov ntxhiab tsw ntxhiab ntawm chav tsev kub. Nws qhov ceev yog 1.44g / mLat 20 ° C, nws qhov kub yog 198-199 ° C (lit.), thiab nws cov ntsiab lus melting yog -3 ° C. Nws tuaj yeem yaj hauv feem ntau cov kuab tshuaj organic thiab yog insoluble hauv dej.
Siv:
Benzyl bromide muaj ntau yam kev siv. Nws yog feem ntau siv nyob rau hauv cov organic synthesis raws li ib tug reagent rau cov tshuaj tiv thaiv. Nws tuaj yeem siv rau hauv kev npaj ntawm esters, ethers, acid chlorides, ether ketones, thiab lwm yam organic compounds. Tsis tas li ntawd, benzyl bromide kuj tseem siv los ua nqaij qaib catalyst, lub teeb stabilizer, resin curing tus neeg sawv cev, thiab nplaim taws retardant rau kev npaj.
Txoj kev:
Benzyl bromide tuaj yeem npaj tau los ntawm cov tshuaj tiv thaiv ntawm benzyl bromide thiab bromine nyob rau hauv cov xwm txheej alkaline. Cov kauj ruam tshwj xeeb yog ntxiv bromine rau benzyl bromide, thiab ntxiv alkali (xws li sodium hydroxide) kom tau txais benzyl bromide tom qab cov tshuaj tiv thaiv.
Cov ntaub ntawv kev nyab xeeb:
Benzyl bromide yog ib qho organic compound uas muaj qee yam toxicity. Nws muaj kev cuam tshuam rau qhov muag, tawv nqaij, thiab ua pa, yog li yuav tsum tau saib xyuas thaum siv cov khoom tiv thaiv tus kheej xws li hnab looj tes, tsom iav, thiab daim npog ntsej muag thaum kov. Tsis tas li ntawd, benzyl bromide tseem ua rau muaj kev kub ntxhov thiab yuav tsum zam kom tsis txhob muaj kev sib cuag nrog cov khoom siv hluav taws xob thiab khaws cia kom deb ntawm cov nplaim taws. Thaum khaws cia thiab tuav benzyl bromide, ua raws li cov txheej txheem kev nyab xeeb tsim nyog thiab khaws cia rau hauv qhov chaw nyab xeeb thiab tsis txhob sib xyaw nrog lwm yam tshuaj.
