Isingeniso
I-4-Methyl-2-nitrophenol iyinhlanganisela ye-organic enefomula yamakhemikhali i-C7H7NO3. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
I-4-methyl -2-nitrophenol iyikristalu eqinile, emhlophe kuya kokuphuzi ngokukhanyayo, inephunga elimnandi elikhethekile ekamelweni lokushisa. Cishe ayincibiliki emanzini, kodwa incibilika kuzincibilikisi zemvelo njenge-ethanol ne-ether.
Sebenzisa:
I-4-methyl -2-nitrophenol isetshenziswa kabanzi ku-organic synthesis. Ngenxa yokuthi inezithako ezimbili ezisebenzayo, i-hydroxyl ne-nitro, ingasetshenziswa njenge-ejenti elwa namagciwane, i-preservative kanye ne-peroxide stabilizer. Ngaphezu kwalokho, ibuye isetshenziswe ekukhiqizeni odayi, ama-pigment kanye nama-fluorescent dyes.
Indlela Yokulungiselela:
I-4-methyl -2-nitrophenol ingahlanganiswa nge-nitrate ye-toluene. Okokuqala, i-toluene ixubene ne-sulfuric acid egxilile phambi kwe-nitric acid futhi isabela ekushiseni okufanelekile isikhathi esithile ukuze ithole umkhiqizo, obese ungaphansi kwezinyathelo ezilandelayo ze-crystallization, filtration kanye nokomisa ukuze ekugcineni uthole i-4- i-methyl-2-nitrophenol.
Ulwazi Lokuphepha:
I-4-Methyl-2-nitrophenol iyinhlanganisela enobuthi ecasulayo futhi ebolayo. Ukuchayeka kuwo kungase kubangele ukulunywa kwesikhumba, ukucasuka kwamehlo kanye nokucasuka kwemigudu yokuphefumula. Ngakho-ke, lapho uyisebenzisa noma uyiphatha, kufanele ugqoke izinto zokuzivikela ezifanele, njengamagilavu, izibuko zokuzivikela kanye nezinto zokuvikela ukuphefumula ukuze ugweme ukuthintana ngokuqondile nokuhogela. Ngaphezu kwalokho, iyinhlanganisela evuthayo futhi kufanele igcinwe kude nomlilo kanye nemithombo yokushisa. Ngesikhathi sokugcina nokuthutha, kufanele kuqashelwe ukugwema ukuxubana nama-oxidants nezinto ezivuthayo. Ngaphansi kokuphathwa ngendlela engafanele, kungase kubangele ukungcola nokulimaza imvelo. Ngakho-ke, izinqubo zokuphepha ezifanele kufanele zilandelwe ukuze kuqinisekiswe ukusetshenziswa okufanele nokulahlwa kwenhlanganisela.
