Cov ntaub ntawv tshuaj lom neeg ntawm Benzenediam NIST Kev siv thiab cov txheej txheem tsim ntawm 1, 3-phenylenediamine (108-45-2). Cov khoom siv tshuaj lom neeg Tsis muaj xim siv lead ua zoo li koob. Yaj hauv dej, ether thiab ethanol.

Feem ntau siv ua cov xim nruab nrab thiab epoxy resin curing agent rau azo dye thiab acazine dye intermediate, feem ntau siv rau hauv kev tsim cov tanning ncaj qha RN, cov txiv kab ntxwv yooj yim, cov xim av yooj yim G, tanning ncaj qha G thiab lwm yam dyes, thiab siv ua cov plaub zas xim, hauv Nyiv, azo dye siv m-phenylenediamine suav txog 90% ntawm tag nrho cov kev siv. Nws kuj tseem siv ua tus neeg sawv cev curing ntawm epoxy resin, coagulant promoter ntawm cement, thiab siv rau hauv cov plaub hau zas xim, mordant, xim tus neeg sawv cev thiab lwm yam. Siv ua tus neeg sawv cev analytical, resin curing agent thiab polymer inhibitor, kuj siv rau hauv kev tsim cov xim rau spectrophotometric kev txiav txim siab ntawm nitrite, kev txiav txim siab ntawm bromate, bromide, chromate, ozone, kub, tooj liab, dichromate, hlau, oxygen thiab platinum, kev txiav txim siab ntawm cov chlorine nquag, chromium, iridium, nitrite thiab palladium. Txoj kev tsim khoom: nitrobenzene yog nitrated los ntawm cov kua qaub sib xyaw rau hauv m-dinitrobenzene, o-dinitrobenzene, p-dinitrobenzene sib tov, thiab tom qab ntawd los ntawm sodium sulfite thiab kua alkali refining m-dinitrobenzene, thiab tom qab ntawd txo cov hmoov hlau lossis hydrogenation txo rau m-phenylenediamine.

Cov khoom siv raw siv: nitrobenzene 1400kg/t, nitric acid 787kg/t, sulfuric acid (98%) 780kg/t, hlau hmoov 3083kg/t.Chav Kawm Cov Tshuaj Lom Zem Qib Siab Mob Siab Mob Qhov Ncauj Qhov Ncauj - Nas LD50:280 mg/kg; Kev noj qhov ncauj - nas LD50:67.7 mg/kg Cov yam ntxwv ntawm kev kub hnyiab nplaim taws; Thaum cua sov, cov roj aniline lom raug tso tawm.
