Nhanganyaya
4-Methyl-2-nitrophenol is an organic compound ine kemikari formula C7H7NO3. Inotevera rondedzero yehunhu hwayo, kushandiswa, kugadzirira uye ruzivo rwekuchengetedza:
Zvakasikwa:
4-methyl -2-nitrophenol yakasimba, chena kusvika kuchiedza yekristaro, ine kunhuhwirira kwakakosha pakupisa kwekamuri. Iyo inenge isinganyungudike mumvura, asi inonyungudika muorganic solvents senge ethanol uye ether.
Shandisa:
4-methyl -2-nitrophenol inoshandiswa zvakanyanya mune organic synthesis. Nekuti ine maviri anoshanda anotsiva, hydroxyl uye nitro, inogona kushandiswa senge antibacterial agent, preservative uye peroxide stabilizer. Mukuwedzera, inoshandiswawo mukugadzirwa kwedhayi, pigments uye fluorescent dhayi.
Kugadzirira nzira:
4-methyl -2-nitrophenol inogona kugadzirwa ne nitration ye toluene. Kutanga, toluene inosanganiswa neconcentrated sulfuric acid pamberi penitric acid uye ikaita pane tembiricha yakakodzera kweimwe nguva yenguva kuti iwane chigadzirwa, iyo inozoiswa pasi pematanho anotevera ekristaro, kusefa uye kuomesa kuti pakupedzisira uwane 4- methyl-2-nitrophenol.
Zvekuchengetedza
4-Methyl-2-nitrophenol chinhu chine chepfu chinogumbura uye chinopisa. Kuratidzwa kwairi kunogona kukonzera kushatirwa kweganda, kushatirwa kwemaziso uye kushatirwa kweturakiti rekufema. Naizvozvo, kana uchiishandisa kana kuibata, unofanirwa kupfeka midziyo yekudzivirira yakakodzera, senge magurovhosi, magirazi ekudzivirira uye zvekufema zvekudzivirira kudzivirira kubata zvakananga uye kufema. Mukuwedzera, iyo isanganiswa inopisa uye inofanira kuchengetedzwa kure nemoto uye kupisa. Panguva yekuchengetedza nekufambisa, kutarisirwa kunofanirwa kutorwa kuti usasanganise neoxidants uye zvinopisa. Mukurapwa zvisina kunaka, zvinogona kukonzera kusvibiswa uye kukuvadza zvakatipoteredza. Nokudaro, maitiro ekuchengetedza akakodzera anofanirwa kuteverwa kuti ave nechokwadi chekushandiswa kwakakodzera uye kuraswa kwekomboni.
