Nga korero matū Benzenediam NIST Nga whakamahi me nga tikanga waihanga o te 1, 3-phenylenediamine (108-45-2).Nga āhuatanga matū Ko te karaihe rite ki te ngira kore tae. Ka whakarewahia ki te wai, te etera me te waiwaro.

Ko te nuinga o te whakamahi hei waikano takawaenga me te kapia epoxy hei kaiwhakaora mo te waikano azo me te waikano acazine takawaenga, i whakamahia i roto i te hanga o te RN tanning tika, te karaka taketake, te parauri taketake G, te tanning tika G me etahi atu tae, ka whakamahia hei tae huruhuru, i Hapani. , Ko te whakamahi i te waikano azo o te m-phenylenediamine mo te 90% o te katoa o te kai. Ka whakamahia ano hei rongoa rongoa mo te epoxy resin, te kaiwhakatairanga coagulant o te ciment, ka whakamahia ki te tae makawe, mordant, kaihoko tae me etahi atu. tauhohenga tātari, kapia rongoa me te aukati polymer, i whakamahia ano hoki ki te whakahiato waikano mo te whakatau spectrophotometric o te nitrite, te whakatau i te bromate, te bromide, te chromate, te ozone, te koura, te parahi, te dichromate, te rino, te hāora me te konukawata, te whakatau o te maota kaha, chromium, iridium, nitrite me te palladium.Te tikanga whakaputa: ka whakahiatohia te nitrobenzene e te waikawa whakauru ki roto i te m-dinitrobenzene, te o-dinitrobenzene, te ranunga p-dinitrobenzene, katahi ano ma te konutai sulfite me te wai kawakore para m-dinitrobenzene, hed ka whakaheke i te paura rino, te whakaheke hauwai ranei ki te m-phenylenediamine.

Te motunga kai rawa: nitrobenzene 1400kg/t, waikawa nitric 787kg/t, waikawa pungatara (98%) 780kg/t, paura rino 3083kg/t.Te Karaehe Matū Paitini Te Tohu Teitei Te Toxicity Acute Toxicity Oral – Kiore LD50:280 mg ;Te whakahaere a-waha – kiore LD50:67.7 mg/kg nga ahuatanga morearea morearea Te mura o te mura;Ka wera ana, ka puta te hau aniline paitini.Ko te rūma ChemicalBook ka whakamahana, ka whakamarokehia i te iti o te pāmahana.Me wehe ke te rokiroki me te kawe i nga taputapu tinei ahi, te wai aerosol, te waro hauwai, te oneone onepu Tikanga mahi TWA 0.1mg/m3 Nga korero haumaru Tapanga Taonga Morearea T,N Waehere Morearea 23/24/25 -36-43-50 / 53-68-40 Whakaahuatanga Haumaru 28-36 / 37-45-60-61-28A Nga Taonga Whakamate Nama UN1673No.6.1 / PG3WGKGermany2RTECS SS7700000F8-10-23 te pāmahana ngingiha ohorere o 560 ° CTSCAYesHazardClass6.1 PackingGroupIII tikanga tikanga 29215119 raraunga matū paitini 108-45-2 (HazardoToxic 56000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 ) Sigmaaldrich (Ingarihi) Acros (Ingarihi) Alfa (Ingarihi) Alfa (Ingarihi) m – Utu Phenylenediamine (Reagent Grade)
