Ulwazi lwamakhemikhali lwe-Benzenediam NISTUkusetshenziswa nezindlela zokwenziwa ze-1, 3-phenylenediamine (108-45-2).Izakhiwo zamakhemikhali Ikristalu engenambala njengenaliti.Incibilika emanzini, i-ether ne-ethanol.

Isetshenziswa kakhulu njengodayi ophakathi nendawo kanye ne-epoxy resin elapha udayi we-azo kanye nodayi we-acazine omaphakathi, osetshenziswa kakhulu ekwenzeni ukushuka okuqondile kwe-RN, i-orange eyisisekelo, isisekelo esinsundu G, ukushuka okuqondile kwe-G kanye nabanye odayi, futhi isetshenziswa njengodayi woboya, eJapan. , ukusetshenziswa kodayi we-azo we-m-phenylenediamine kubala u-90% wokusetshenziswa okuphelele.Ibuye isetshenziswe njenge-ejenti yokwelapha ye-epoxy resin, umgqugquzeli we-coagulant kasimende, futhi isetshenziselwa udayi wezinwele, i-mordant, i-ejenti yombala nokunye. i-analytical reagent, i-resin ephulukisa i-ejenti kanye ne-polymer inhibitor, nayo isetshenziswa ekuhlanganiseni udayi wokunqunywa kwe-spectrophotometric ye-nitrite, ukunqunywa kwe-bromate, i-bromide, i-chromate, i-ozone, igolide, ithusi, i-dichromate, insimbi, umoya-mpilo neplatinamu, ukuzimisela kwe-chlorine esebenzayo, I-chromium, i-iridium, i-nitrite ne-palladium.Indlela yokukhiqiza: i-nitrobenzene ifakwa nge-asidi exubile ibe yi-m-dinitrobenzene, i-o-dinitrobenzene, ingxube ye-p-dinitrobenzene, bese kuba yi-sodium sulfite kanye ne-alkali ecwenga uketshezi m-dinitrobenzene, id bese kuncishiswa i-iron powder noma ukunciphisa i-hydrogenation ibe m-phenylenediamine.

Isilinganiso sokusetshenziswa kwempahla eluhlaza: i-nitrobenzene 1400kg/t, i-nitric acid 787kg/t, i-sulfuric acid (98%) 780kg/t, i-iron powder 3083kg/t.Ikilasi Lezinto Ezinobuthi Ubuthi Ibanga Lobuthi Obuphezulu I-Acute Toxicity Oral – Rats LD50:280 mg/ ;Ukuphatha ngomlomo – igundane LD50:67.7 mg/kg izici zengozi yokuvutha Ukuvutha kwelangabi;Uma kushisa, kukhishwa igesi enobuthi ye-aniline.Igumbi le-ChemicalBook lifakwa umoya futhi lomiswe ezingeni lokushisa eliphansi.Indawo ehlukene yokulondoloza kanye nokuthuthwa kwezinto ezicisha umlilo, amanzi aerosol, i-carbon dioxide, inhlabathi eyisihlabathi Izinga lomsebenzi TWA 0.1mg/m3 Ulwazi lwezokuphepha Impahla Eyingozi Ilebula T,N Ikhodi Yesigaba Esiyingozi 23/24/25 -36-43-50/53-68-40 Incazelo Yezokuphepha 28-36/37-45-60-61-28A Impahla Eyingozi Ezokuthutha No. UN1673No.6.1 / PG3WGKGermany2RTECS SS7700000F8-10-23 izinga lokushisa elizenzakalelayo elingu-560 ° CTSCAYesHazardClass6.1 PackingGroupIII ikhodi yangokwezifiso 29215119 idatha yento enobuthi 108-45-2 (Hazardobstanxic; ) Sigmaaldrich (English) Acros (English) Alfa (English) Alfa (English) m – Phenylenediamine Price (Reagent Grade)
