3-nitrotoluene; m-nitrotoluene

Ulwazi Oluyisisekelo:

Bisingeniso esibuhlungu: I-3-nitrotoluene itholakala ku-toluene nitrate ne-asidi exutshwe ngaphansi kuka-50℃, bese ihlukaniswa futhi icwengisiswe. Ngezimo ezihlukahlukene zokusabela kanye nama-catalysts, imikhiqizo ehlukene ingatholakala, njenge-o-nitrotoluene, i-p-nitrotoluene, i-m-nitrotoluene, i-2, i-4-dinitrotoluene ne-2, 4, i-6-trinitrotoluene. I-nitrotoluene kanye ne-dinitrotoluene zibalulekile emithini, odayi kanye nezibulala-zinambuzane. Ezimweni ezijwayelekile zokusabela, kunemikhiqizo eminingi ye-ortho kune-para-sites ku-intermediate emithathu ye-nitrotoluene, kanye nama-para-sites angaphezu kwama-para-site. Njengamanje, imakethe yasekhaya inesidingo esikhulu sendawo eseduze ne-para-nitrotoluene, ngakho-ke i-nitration yendawo ye-toluene ifundwa ekhaya naphesheya, ngethemba lokukhulisa isivuno se-para-toluene eseduze ngangokunokwenzeka. Nokho, awukho umphumela omuhle okwamanje, futhi ukwakheka kwenani elithile le-m-nitrotoluene akunakugwenywa. Ngenxa yokuthi ukuthuthukiswa kanye nokusetshenziswa kwe-p-nitrotoluene akuzange kugcinwe ngesikhathi, umkhiqizo we-nitrotoluene nitration ungathengiswa kuphela ngentengo ephansi noma inani elikhulu le-inventory ligcwele ngokweqile, okuholela ekusetshenzisweni okukhulu kwemithombo yamakhemikhali.
