4-Nitrophenol(CAS#100-02-7)
khalidwe
Makhiristo achikasu owala, opanda fungo. Kusungunuka pang'ono m'madzi kutentha (1.6%, 250 ° C). Amasungunuka mu ethanol, chlorophenol, ether. Zosungunuka mu carbonate solutions za caustic ndi alkali zitsulo ndi zachikasu. Ndi yoyaka, ndipo pali chiopsezo cha kuyaka kuphulika ngati lotseguka lawi, kutentha kwambiri kapena kukhudzana ndi okosijeni. Mpweya woopsa wa ammonia oxide flue umatulutsidwa ndi kupatukana kwa kutentha.
Njira
Amakonzedwa ndi nitrification wa phenol mu o-nitrophenol ndi p-nitrophenol, ndiyeno kulekanitsa o-nitrophenol ndi distillation nthunzi, komanso akhoza hydrolyzed ku p-chloronitrobenzene.
ntchito
Amagwiritsidwa ntchito ngati chosungira chikopa. Ndiwopangira zopangira utoto, mankhwala osokoneza bongo, ndi zina zambiri, ndipo zitha kugwiritsidwanso ntchito ngati chizindikiro cha pH cha monochrome, ndikusintha kwamtundu wa 5.6 ~ 7.4, kusintha kuchokera ku mtundu wopanda utoto kukhala wachikasu.
chitetezo
Khoswe ndi makoswe pakamwa LD50: 467mg/kg, 616mg/kg. Zapoizoni! Lili ndi mphamvu yowonongeka pakhungu. Ikhoza kuyamwa kudzera pakhungu ndi kupuma thirakiti. Kuyesera kwa nyama kungayambitse kutentha kwa thupi komanso kuwonongeka kwa chiwindi ndi impso. Ziyenera kusungidwa mosiyana ndi zotsekemera, zochepetsera, alkalis, ndi mankhwala odyedwa, ndipo zisasakanizidwe.
