Iji p-chlorophenol dị ka akụrụngwa, 2-nitro-p-chlorophenol nwere ike mee site na nitration, wee belata ka ọ bụrụ p-chloro-o-aminophenol.
(1) Mmepụta 2-nitro-p-chlorophenol: Iji p-chlorophenol dị ka akụrụngwa, nitrification na nitric acid.Tinye p-chlorophenol distilled nwayọọ nwayọọ n'ime tank nke nwere 30% nitric acid, debe okpomọkụ na 25-30.℃, kpalie ihe dị ka awa 2, tinye ice ka ọ dị jụụ n'okpuru 20℃, kposara, nzacha, ma saa achicha nzacha na Congo Red, ngwaahịa 2-nitrop-chlorophenol nwetara.
(2) Enwere ụzọ abụọ maka mbelata 2-nitro-p-chlorophenol.Otu bụ iji sodium disulfide belata.Nke mbụ, a na-eji 30% sodium hydroxide solution na sọlfọ ntụ ntụ mee sodium disulfide ngwọta, na 2-nitro-p-phenol na-agbakwunyere n'ike-n'ike iji meghachi omume na 95-100.°C, na mmeghachi omume agwụla.Mgbe filtration na-ekpo ọkụ, a na-ewepụ ihe nzacha ahụ na mmiri soda, mee ka ọ dị mma ruo 20°C, nzacha, a na-asakwa achicha nzacha ka ọ bụrụ nnọpụiche iji nweta ngwaahịa 2-nitro-p-chlorophenol emechara.
Nke abụọ bụ usoro mbelata hydrogenation.N'ebe ọnụnọ nke nickel catalyst, a na-edozi nkwusioru mmiri nke 2-nitro-p-chlorophenol na pH = 7 na sodium dihydrogen phosphate hydrate na sodium hydroxide aqueous solution na nrụgide hydrogen nke 4.05Mpa na Hydrogenation Mbelata na 60.°C. Mgbe mmeghachi omume ahụ mechara, hapụ nrụgide ahụ, dochie ya na nitrogen, kpoo ọkụ ruo 95°C, dozie pH = 10.7 na sodium hydroxide, tinye carbon arụ ọrụ na ụwa diatomaceous, kpalie ike, na nzacha.Emeziri nzacha ahụ ka ọ bụrụ pH=5.2 (20°C) nwere hydrochloric acid gbadoro anya, jụrụ ya ka ọ bụrụ 0°C, kpochara, akpọnwụwo ma jiri sodium bisulfite gwọọ ya.Tinyegharịa ọrụ ahụ ugboro anọ, wee gbasaa na 2.67kpa, kpokọta akụkụ ndị ahụ gburugburu 80.°C, ma kpoo ha ka ha nweta ngwaahịa na mkpụrụ nke 97.7%.
