Intshayelelo
I-4-Methyl-2-nitrophenol i-organic compound kunye ne-chemical formula C7H7NO3. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:
Indalo:
I-4-methyl -2-nitrophenol iqinile, imhlophe ukuya kwikristale ekhanyayo ephuzi, inevumba elimnandi elikhethekileyo kwiqondo lokushisa. Iphantse yanganyibiliki emanzini, kodwa iyanyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol kunye ne-ether.
Sebenzisa:
I-4-methyl -2-nitrophenol isetyenziswa ngokubanzi kwi-organic synthesis. Ngenxa yokuba inamalungu amabini asebenzayo, i-hydroxyl kunye ne-nitro, inokusetyenziswa njenge-antibacterial agent, i-preservative kunye ne-peroxide stabilizer. Ukongeza, isetyenziselwa ukuveliswa kwedayi, i-pigments kunye ne-fluorescent dyes.
Indlela yokulungiselela:
I-4-methyl -2-nitrophenol inokwenziwa nge-nitration ye-toluene. Okokuqala, i-toluene ixutywe kunye ne-asidi ye-sulfuric egxininisiweyo phambi kwe-nitric acid kwaye iphendule kwiqondo lokushisa elifanelekileyo kwixesha elithile lokufumana imveliso, enokuthi ixhomekeke kumanyathelo alandelayo e-crystallization, i-filtration kunye nokomisa ukuze ekugqibeleni ifumane i-4- imethyl-2-nitrophenol.
Ulwazi ngoKhuseleko:
I-4-Methyl-2-nitrophenol i-compound enetyhefu ecaphukisayo kunye neyonakalisayo. Ukutyhileka kuyo kunokubangela ukucaphuka kwesikhumba, ukucaphuka kwamehlo kunye nokucaphuka kwendlela yokuphefumla. Ke ngoko, xa usebenzisa okanye uyiphatha, kufuneka unxibe izixhobo ezifanelekileyo zokukhusela, ezinjengeeglavu, iiglasi ezikhuselayo kunye nezixhobo zokhuselo lokuphefumula ukuphepha ukunxibelelana ngokuthe ngqo kunye nokuphefumla. Ukongeza, iyikhompawundi enokutsha kwaye kufuneka igcinwe kude nomlilo kunye nemithombo yobushushu. Ngexesha lokugcinwa kunye nokuthutha, kufuneka kuthathelwe ingqalelo ukuphepha ukuxuba kunye ne-oxidants kunye nezinto ezinokutsha. Phantsi konyango olungafanelekanga, lunokubangela ungcoliseko nokwenzakala kokusingqongileyo. Ngoko ke, izenzo ezifanelekileyo zokhuseleko kufuneka zilandelwe ukuqinisekisa ukusetyenziswa ngokufanelekileyo kunye nokulahlwa kwekhompawundi.
