Taw qhia

Nitrobenzene) yog cov organic compound uas tuaj yeem ua cov khoom siv dawb crystalline lossis cov kua daj daj nrog cov aroma tshwj xeeb. Cov hauv qab no yog kev qhia txog qee yam ntawm cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm nitrobenzene:

Zoo:

Nitrobenzene yog insoluble hauv dej tab sis soluble hauv cov kuab tshuaj organic xws li cawv thiab ethers.

Nws tuaj yeem tau txais los ntawm nitrating benzene, uas yog tsim los ntawm reacting benzene nrog concentrated nitric acid.

Nitrobenzene yog ib qho chaw ruaj khov, tab sis nws kuj yog tawg thiab muaj cov nplaim hluav taws kub.

Siv:

Nitrobenzene yog ib qho tseem ceeb ntawm cov khoom siv raw thiab siv dav hauv cov organic synthesis.

Nitrobenzene kuj tseem siv tau los ua ib qho ntxiv hauv cov kuab tshuaj, xim thiab txheej.

Txoj kev:

Txoj kev npaj ntawm nitrobenzene tsuas yog tau los ntawm nitrification cov tshuaj tiv thaiv ntawm benzene. Hauv chav kuaj, benzene tuaj yeem tov nrog concentrated nitric acid thiab concentrated sulfuric acid, nplawm ntawm qhov kub thiab txias, thiab tom qab ntawd yaug nrog dej txias kom tau nitrobenzene.

Cov ntaub ntawv kev nyab xeeb:

Nitrobenzene yog ib qho tshuaj lom neeg, thiab raug los yog nqus ntawm nws cov vapor tuaj yeem ua rau lub cev puas tsuaj.

Nws yog ib qho hluav taws kub thiab tawg sib txuas thiab yuav tsum tsis txhob sib cuag nrog cov khoom siv hluav taws xob.

Cov cuab yeej tiv thaiv tus kheej xws li hnab looj tes tiv thaiv thiab tsom iav yuav tsum hnav thaum tuav nitrobenzene, thiab yuav tsum tau tswj xyuas qhov chaw ua haujlwm zoo.

Thaum muaj kev sib tsoo los yog kev sib tsoo, kev ntsuas tsim nyog yuav tsum tau ua sai sai los ntxuav thiab pov tseg. Ua raws li cov cai lij choj thiab cov cai tswj xyuas kom pov tseg cov khoom pov tseg kom raug.
