Physical Data
Maonekedwe: ufa woyera kapena woyera wa crystalline.
Kuyera: ≥98.0%
Malo osungunuka: 140～142℃
Kusungunuka: kusungunuka m'madzi, kusungunuka m'madzi pa 20°C <0.1 g/100 mL, sungunuka mu etha, ethanol ndi chloroform.
Kukhazikika: kukhazikika kukakhala kowuma, kosavuta kukhala okosijeni komanso utoto mumlengalenga wonyezimira, kuyaka ngati lawi lotseguka;kutentha kwakukulu kumatulutsa poizoni wa chloride ndi mpweya wa nitrogen oxide.
Njira Yopangira
Ntchito ngati utoto wapakatikati, komanso ntchito yokonza fulorosenti whitening wothandizira utoto intermediates, ndi ntchito kupanga fulorosenti whitening wothandizira DT.
Njira Yopangira
Pogwiritsa ntchito p-chlorophenol ngati zopangira, 2-nitro-p-chlorophenol imatha kupangidwa kudzera mu nitration, kenako kuchepetsedwa kupanga p-chloro-o-aminophenol.
(1) Kupanga kwa 2-nitro-p-chlorophenol: Kugwiritsa ntchito p-chlorophenol ngati zopangira, nitrification ndi nitric acid.Onjezani p-chlorophenol yosungunuka pang'onopang'ono mu thanki yotenthedwa ndi 30% nitric acid, sungani kutentha kwa 25-30.℃, yambitsani kwa maola awiri, onjezani ayezi kuti azizizira pansi pa 20℃, precipitate, fyuluta, ndikutsuka keke ya fyuluta ku Congo Red, mankhwala 2-nitrop-chlorophenol amapezeka.
(2) Pali njira ziwiri zochepetsera 2-nitro-p-chlorophenol.Chimodzi ndicho kuchepetsa ndi sodium disulfide.Choyamba, 30% ya sodium hydroxide solution ndi sulfure ufa amagwiritsidwa ntchito popanga sodium disulfide solution, ndipo 2-nitro-p-phenol imawonjezeredwa molingana ndi 95-100.°C, ndipo zotsatira zatha.Pambuyo kusefedwa kotentha, kusefa kumachepetsedwa ndi madzi a soda, utakhazikika mpaka 20°C, amasefedwa, ndipo keke ya fyuluta imatsukidwa kuti isalowererepo kuti ipeze chomaliza 2-nitro-p-chlorophenol.
Yachiwiri ndi njira yochepetsera hydrogenation.Pamaso pa chothandizira nickel, kuyimitsidwa kwamadzi kwa 2-nitro-p-chlorophenol kumasinthidwa kukhala pH = 7 ndi sodium dihydrogen phosphate hydrate ndi sodium hydroxide amadzimadzi njira pa hydrogen kuthamanga 4.05Mpa ndi Hydrogenation kuchepetsa pa 60.°C. Zochita zikatha, tulutsani mphamvuyo, m'malo mwake ndi nayitrogeni, kutentha mpaka 95°C, sinthani pH = 10.7 ndi sodium hydroxide, onjezerani activated carbon ndi diatomaceous earth, gwedezani mwamphamvu, ndi fyuluta.Sefayi idasinthidwa kukhala pH=5.2 (20°C) yokhala ndi hydrochloric acid, yokhazikika mpaka 0°C, zosefedwa, zouma, ndi kuthandizidwa ndi sodium bisulfite.Bwerezani ntchitoyo kanayi, kenako distill pa 2.67kpa, sonkhanitsani tizigawo tozungulira 80.°C, ndikuwumitsa kuti mupeze zokolola za 97.7%.
Main Application
Ntchito yaikulu ya p-chloro-o-aminophenol ndi ngati utoto wapakatikati, pokonzekera asidi mordant RH, asidi ovuta violet 5RN ndi utoto wotakataka, etc., komanso pokonza zopangira chlorzoxazone.
Kuyika, Kusungirako ndi Mayendedwe
Ndi mankhwala owopsa, ndipo amapakidwa mu ng'oma zachitsulo zokwana 25kg, ndipo nyumba yosungiramo katunduyo imakhala ndi mpweya wabwino, wotentha komanso wouma, ndipo imatetezedwa ku dzuwa.Khalani kutali ndi gwero la kutentha kwa moto, ndipo sungani ndi kunyamula mosiyana ndi zidulo, ma okosijeni, zowonjezera chakudya, ndi ma okosijeni.
