Solubility: aan milmayn biyaha, milmay biyaha 20°C <0.1 g/100 mL, oo ku milma ether, ethanol iyo chloroform.
Xasilooni: xasiloon marka uu qalalan yahay, fududahay in la oksidhid iyo midab hawo qoyan leh, guban kara haddii uu ololka furan yahay;kulaylka sare waxa uu sii daayaa chloride sunta ah iyo gaasaska oksaydh ee nitrogen.
Habka wax soo saarka
Waxa loo istcimaalaa dhex dhexaadiye dheeha, oo sidoo kale loo isticmaalo diyaarinta dhex dhexaadiyayaasha dheeha caddaynta fluorescent, oo loo isticmaalo soo saarista wakiilka caddaynta fluorescent DT.
Habka wax soo saarka
Isticmaalka p-chlorophenol sida alaab cayriin ah, 2-nitro-p-chlorophenol waxaa lagu samayn karaa nitration, ka dibna la dhimo si loo sameeyo p-chloro-o-aminophenol.
(1) Soo saarista 2-nitro-p-chlorophenol: Isticmaalka p-chlorophenol wax cayriin ah, nitrification leh nitric acid.Ku dar p-chlorophenol la miiray si tartiib ah haanta la karkariyey oo leh 30% nitric acid, heerkulka ku hay 25-30℃, walaaq ilaa 2 saacadood, ku dar baraf si aad ugu qaboojiso wax ka hooseeya 20℃, daadi, sifee, oo ku dhaq keega filtarta ah ee Congo Cas, badeecada 2-nitrop-chlorophenol waa la helay.
(2) Waxaa jira laba hab oo loo yareeyo 2-nitro-p-chlorophenol.Mid waa in lagu yareeyo sodium disulfide.Marka hore, 30% xal sodium hydroxide iyo budada sulfur ayaa loo isticmaalaa si loo sameeyo xal sodium disulfide, iyo 2-nitro-p-phenol ayaa lagu daraa saamiga si looga falceliyo 95-100°C, falcelintiina way dhammaatay.Sifeynta kulul ka dib, sifeynta ayaa lagu dhex milmay biyo baking soda, la qaboojiyey ilaa 20°C, la sifeeyay, iyo keega shaandhada waxaa lagu dhaqaa dhexdhexaadnimo si loo helo badeecada dhammaatay ee 2-nitro-p-chlorophenol.
Midda labaad waa habka dhimista hydrogenation.Joogitaanka nikkel-kicinta, joojinta biyaha ee 2-nitro-p-chlorophenol waxaa lagu hagaajiyaa pH = 7 oo leh sodium dihydrogen phosphate hydrate iyo sodium hydroxide aqueous°C. Ka dib marka falcelintu dhammaato, sii daa cadaadiska, ku beddel nitrogen, kuleyl ilaa 95°C, ku hagaaji pH=10.7 oo leh sodium hydroxide, ku dar kaarboon firfircoon iyo dhulka diatomaceous, si xoog leh u walaaq, oo filter.Sifeynta waxaa lagu hagaajiyay pH=5.2 (20°C) leh hydrochloric acid oo la qaboojiyey ilaa 0°C, la sifeeyay, la qalajiyey, laguna daweeyay sodium bisulfiteKu celi qalliinka afar jeer, ka dibna ka sii wad 2.67kpa, ururi jajabyada ilaa 80°C, oo u qalaji si ay u helaan wax-soo-saarka 97.7%.
Codsiga ugu weyn
Isticmaalka ugu weyn ee p-chloro-o-aminophenol waa dhexdhexaad dhexdhexaad ah, loogu talagalay diyaarinta mordant acid RH, 5RN violet kakan iyo midabyo fal-celin ah, iwm, iyo sidoo kale diyaarinta chlorzoxazone alaabta ceeriin.
Baakadaha, Kaydinta iyo Gaadiidka
Waa kiimiko khatar ah, waxaana lagu baakadeeyay 25kg oo durbaan bir ah, bakhaarkuna waa hawo, heerkulkiisu yar yahay oo engegan, waxaana laga ilaaliyaa iftiinka qorraxda tooska ah.Ka fogow ilaha kulaylka dabka, oo u kaydi oo u qaado si gooni ah asiidhyada, oksaydhiyeyaasha, cuntada lagu daro, iyo oksaydhiyeyaasha.
