p-Phenylene diamine; 1,4-diaminobenzene

Mwala woyera. Amakhala duwa powala. Amakhala wofiirira mumlengalenga. Malo osungunuka 140 ℃. Malo otentha 267 ℃. Ikhoza kukhala sublimated. Kusungunuka pang'ono m'madzi ozizira, kusungunuka mu ethanol, ether, chloroform ndi benzene. Imachita ndi ma inorganic acids kupanga mchere womwe umasungunuka mosavuta m'madzi. Amagwiritsidwa ntchito popanga utoto wa azo ndi utoto wa sulfure, etc., ndipo amagwiritsidwa ntchito ngati utoto waubweya (Fur Black D, Ursol D kapena Fur Black D, Ursol D kapena Fur Black D) ndi othandizira omwe akutukuka. Izi ndi za Category 3 carcinogens. Amapangidwa ndi kuchepa kwa p-nitroaniline.

Njira yopangira

Imapezedwa pochepetsa p-nitroaniline ndi ufa wachitsulo mu acidic sing'anga. Ikani ufa wachitsulo mu hydrochloric acid, kutentha mpaka 90 ° C, ndi kuwonjezera p-nitroaniline pamene mukuyambitsa. Kuwonjezera kumalizidwa, itani pa 95-100 ° C kwa maola 0.5, ndiyeno onjezerani hydrochloric acid dropwise kuti mutsirize kuchepetsedwa kwa Chemicalbook. Mukaziziritsa, chepetsani ndi sodium carbonate solution yokhala ndi pH 7-8, wiritsani ndi fyuluta mukatentha, ndikutsuka keke ya fyuluta ndi madzi otentha. Phatikizani zosefera ndi madzi ochapira, sungani pansi pa kupanikizika kocheperako, crystallize ndi kuziziritsa kapena distill pansi pa kupanikizika kochepa kuti mupeze p-phenylenediamine ndi zokolola za 95%.
