4-Nitrophenol(CAS#100-02-7)
quality
Makristasi eyero akajeka, asinganhuhwi. Kunyungudika zvishoma mumvura pane tembiricha yemumba (1.6%, 250 °C). Soluble mu ethanol, chlorophenol, ether. Soluble mu carbonate solutions ye caustic uye alkali simbi uye yero. Inopfuta, uye kune njodzi yekuputika kwekupisa kana murazvo wakavhurika, kupisa kwakanyanya kana kusangana neoxidant. Iyo ine chepfu ammonia oxide flue gasi inoburitswa nekuparadzaniswa kwekupisa.
Nzira
Inogadzirwa ne nitrification ye phenol mu o-nitrophenol uye p-nitrophenol, uyezve kupatsanura o-nitrophenol ne steam distillation, uye inogona zvakare kuve hydrolyzed kubva p-chloronitrobenzene.
use
Inoshandiswa seganda rekuchengetedza. Iriwo zvinhu zvakasvibirira zvekugadzirwa kwedhayi, zvinodhaka, nezvimwewo, uye zvinogonawo kushandiswa se pH chiratidzo che monochrome, ine ruvara rwekuchinja kwemavara 5.6 ~ 7.4, kuchinja kubva kune isina ruvara kusvika kune yero.
kuchengeteka
Mouse uye gonzo remuromo LD50: 467mg/kg, 616mg/kg. Chepfu! Iine simba rakasimba rinoshungurudza paganda. Inogona kutorwa kuburikidza neganda uye nzira yekufema. Kuedza kwemhuka kunogona kukonzera kuwedzera kwekushisa kwemuviri uye kukuvara kwechiropa neitsvo. Inofanira kuchengetwa zvakasiyana kubva kune oxidants, zvinoderedza, alkalis, uye makemikari anodyika, uye haafaniri kusanganiswa.
