Phenylene diamine:Phenylene diamine yeyona diamine elula enevumba elimnandi. Kukho iintlobo ezi-3 ze-isomer, ezizezi, o-phenylenediamine, m-phenylenediamine, kunye ne-p-phenylenediamine. I-P-Phenylenediamine, eyaziwa ngokuba yi-Ursol, yikristale engenambala ekhawuleza i-oxidize ibe mnyama emoyeni. Iqondo lokubila lingama-267°C. Inyibilika emanzini, ethanol kunye ne-ether. Isetyenziswa njengemathiriyeli ekrwada okanye ephakathi kwidayi, i-vulcanization accelerator yerabha, umphuhlisi kushishino lweefoto, iidayi zoboya kunye nedayi yeenwele. Abo banxibelelana ngakumbi ziidayi zeenwele, abachebi kunye nabo badaya iinwele zabo rhoqo. Inokungena emzimbeni womntu ngolusu. I-oxidized intermediates ine-degrees ezahlukeneyo zokuva kwaye inokubangela i-eczema-like okanye i-lichenoid dermatitis. Idla ngokuvela ebusweni, entanyeni nasemaphahleni nakwamanye amagophe esikhumba, afana neekona zomlomo, iikona zamehlo, kunye neempumlo. Yonakele. Ukuphefumla uthuli lwayo kunokubangela isifuba somoya. Iimpawu zetyhefu yomlomo ziyafana nezo zetyhefu ye-aniline. Ikakhulu thatha unyango lweempawu. I-O-phenylenediamine ikwabizwa ngokuba yi-1,2-diaminobenzene kunye ne-1,2-phenylenediamine. Iikristale ezimhlophe ukuya tyheli ezifana negqabi ziphuma emanzini, kwaye iikristale zeprismatic ziphuma kwikloroform. Kulula ukutshintsha umbala xa utyhilekile emoyeni, ukusuka kumhlophe ukuya kumthubi Chemicalbook, omdaka, omfusa, kwaye ekugqibeleni ube mnyama. Uxinzelelo olunxulumeneyo yi-1.2698. Indawo yokunyibilika yi-103~104℃. Indawo yokubilisa yi256℃258℃. I-soluble kancinane emanzini abandayo (4.15 ku-35 ° C), i-soluble ngokulula emanzini ashushu (733 ku-81 ° C), i-ethanol, i-ether, i-chloroform kunye ne-benzene. Isabela nge-asidi ye-inorganic ukuvelisa ityuwa enyibilikayo emanzini; isisombululo esinamanzi siphendula nge-carbon disulfide ukuvelisa i-2-mercaptobenzimidazole; isabela nge-carbon dioxide phantsi koxinzelelo lokuvelisa i-benzimidazolone. Le mveliso inetyhefu. Emva kokuphefumla, kunokubangela ukuphazamiseka okubonakalayo, ukudibanisa nolusu, kubangele ukuvuvukala, ukungena kwamehlo, kwaye kubangele ukuvuvukala. Impuku yomlomo LD501070mg/kg. I-M-phenylenediamine yikristale yerhombic, ekhutshwe ngokukhawuleza kwi-yellow-brown emoyeni. Umxhuzulane okhethekileyo yi-1.139. Iqondo lokunyibilika lingama-62.8°C kwaye indawo yokubila yi-284°C. I-Soluble emanzini, utywala, i-ketone, njl njl. Isetyenziswe kwishishini lekhemikhali yedayi, kwaye njenge-arhente yokunyanga iiplastiki, njl. Ityhefu ebukhali inokubangela i-methemoglobinemia, ukonakala kwesibindi kunye ne-hemolytic anemia.
