soluble mu ethanol, ether uye benzene, inonyungudika zvishoma mumvura.
The Pure product is colorless to pale yellow oily liquid. Soluble mu ethanol, ether uye benzene, inonyungudika mumvura.
Shandisa Nitrobenzene yakakosha organic pakati payo. Nitrobenzene yakasvibiswa nesulfur trioxide kuti iwane m-nitrobenzene sulfonic acid. Inogona kushandiswa sedhayi yepakati, mild oxidant uye anti-dhayi munyu s. Nitrobenzene yakasvibiswa ne chlorosulfonic acid kuti iwane m-nitrobenzenesulfonyl chloride, iyo yakashandiswa sepakati pedhayi, mushonga uye zvichingodaro. Nitrobenzene inonatswa kuM-nitrochlorobenzene, iyo inoshandiswa zvakanyanya mukugadzirwa kwedhayi nemishonga yezvipembenene. Mushure mekudzikisa, M-chloroaniline inogona kuwanikwa. Inoshandiswa sedhayi orenji GC, zvakare imishonga, mushonga wezvipembenene, fluorescent whitening agent, organic pigment intermediates. Nitrobenzene re-nitration inogona kuva m-dinitrobenzene, nekutapudza inogona kuva m-phenylenediamine, inoshandiswa sedhayi yepakati, epoxy resin kurapa agent, petroleum additives, Cement accelerator, M-dinitrobenzene sesodium sulfide yechikamu zvakare musimboti kuM-nitroaniline. Kune iyo dhayi orenji base R, ndeye yepakati yeazo dhayi uye organic pigments.

Nhanganyaya

Nitrobenzene) musanganiswa weorganic unogona kuva muchenera wakasimba kana kuti yero mvura ine hwema hwakakosha. Iyi inotevera sumo kune zvimwe zvezvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza yenitrobenzene:

 

Hunhu:

Nitrobenzene hainyungudike mumvura asi inonyungudika muzvinonyungudutsa zvine mwero zvakaita sedoro nemaether.

Inogona kuwanikwa nenitrate benzene, iyo inogadzirwa nekuita benzene ine concentrated nitric acid.

Nitrobenzene ikomboni yakagadzikana, asi zvakare inoputika uye ine yakanyanya kupisa.

 

Shandisa:

Nitrobenzene ikemikari yakakosha mbishi zvinhu uye inoshandiswa zvakanyanya muorganic synthesis.

Nitrobenzene inogona zvakare kushandiswa sechinhu chinowedzera muzvinonyungudutsa, pendi uye machira.

 

Nzira:

Nzira yekugadzirira ye nitrobenzene inonyanya kuwanikwa ne nitrification reaction ye benzene. Murabhoritari, benzene inogona kusanganiswa neconcentrated nitric acid uye concentrated sulfuric acid, inobvongodzwa pakudziya kwakaderera, yozosukuzwa nemvura inotonhora kuti iwane nitrobenzene.

 

Zvekuchengetedza

Nitrobenzene musanganiswa une muchetura, uye kuratidzwa kana kufemerwa nemhute yaro kunogona kukonzera kukanganisa kumuviri.

Icho chinhu chinopisa uye chinoputika uye chinofanirwa kudzivirira kusangana nepanopisa.

Zvidziviriro zvemunhu zvakadai semagirovhosi ekudzivirira uye magirazi zvinofanirwa kupfekwa kana uchibata nitrobenzene, uye nzvimbo yekushanda ine mhepo yakanaka inofanirwa kuchengetedzwa.

Muchiitiko chekuvuza kana tsaona, matanho akakodzera anofanira kutorwa nekukurumidza kuti acheneswe uye kuraswa. Tevedzera mitemo nemirau yakakodzera kurasira zvakanaka tsvina inogadzirwa.
