Selelekela
4-Methyl-2-nitrophenol ke motsoako oa manyolo o nang le foromo ea lik'hemik'hale C7H7NO3. E latelang ke tlhaloso ea sebopeho sa eona, ts'ebeliso, tokiso le tlhaiso-leseling ea polokeho:
Tlhaho:
4-methyl -2-nitrophenol ke kristale e tiileng, e tšoeu ho isa ho bosehla bo bobebe, e na le monko o khethehileng o nkhang hamonate mocheso oa kamore. E batla e sa qhibilihe ka metsing, empa e qhibiliha ka har'a metsoako ea tlhaho e kang ethanol le ether.
Sebelisa:
4-methyl -2-nitrophenol e sebelisoa haholo ho organic synthesis. Hobane e na le lintho tse peli tse sebetsang, e leng hydroxyl le nitro, e ka sebelisoa e le antibacterial agent, preservative le peroxide stabilizer. Ho feta moo, e boetse e sebelisoa ho hlahisa lidae, li-pigments le li-fluorescent dyes.
Mokhoa oa ho itokisa:
4-methyl -2-nitrophenol e ka etsoa ka nitration ea toluene. Ntlha ea pele, toluene e kopantsoe le concentrated sulfuric acid ka pel'a nitric acid 'me e itšoara ka mocheso o loketseng ka nako e itseng ho fumana sehlahisoa, ebe se tlas'a mehato e latelang ea crystallization, filtration le ho omisa ho fihlela qetellong ho fumana 4- methyl-2-nitrophenol.
Lintlha tsa Tšireletseho:
4-Methyl-2-nitrophenol ke motsoako o chefo o halefisang le o senyang. Ho pepesetsoa ho eona ho ka baka ho teneha ha letlalo, ho hlohlona ha mahlo le ho hlohlona ha phefumoloho. Ka hona, ha u e sebelisa kapa u e tšoara, u lokela ho apara lisebelisoa tse loketseng tsa tšireletso, tse kang liatlana, likhalase tse sireletsang le lisebelisoa tsa tšireletso ea phefumoloho ho qoba ho kopana ka ho toba le ho hema. Ho phaella moo, ke motsoako o tukang 'me o lokela ho bolokoa hole le mehloli ea mollo le mocheso. Nakong ea polokelo le lipalangoang, tlhokomelo e lokela ho nkoa ho qoba ho tsoakana le li-oxidants le lintho tse tukang. Tlas'a phekolo e sa lokelang, e ka baka tšilafalo le kotsi tikolohong. Ka hona, mekhoa e nepahetseng ea tšireletso e lokela ho lateloa ho netefatsa tšebeliso e nepahetseng le ho lahla motsoako.
