Benzenediam NIST chemical informationUses and synthetic methods of 1, 3-phenylenediamine (108-45-2). Chemical properties Colorless needle-like crystal.Soluble in water, ether and ethanol.

Mainly used as dye intermediate and epoxy resin curing agent for azo dye and acazine dye intermediate, mainly used in the manufacture of direct tanning RN, basic orange, basic brown G, direct tanning G and other dyes, and used as fur dye, in Japan, azo dye consumption of m-phenylenediamine accounts for 90% of the total consumption.It is also used as curing agent of epoxy resin, coagulant promoter of cement, and used in hair dye, mordant, color agent and so on.Used as an analytical reagent, resin curing agent and polymer inhibitor, also used in the synthesis of dyes for spectrophotometric determination of nitrite, determination of bromate, bromide, chromate, ozone, gold, copper, dichromate, iron, oxygen and platinum, determination of active chlorine, chromium, iridium, nitrite and palladium.Production method: nitrobenzene is nitrated by mixed acid into m-dinitrobenzene, o-dinitrobenzene, p-dinitrobenzene mixture, and then by sodium sulfite and liquid alkali refining m-dinitrobenzene, and then iron powder reduction or hydrogenation reduction to m-phenylenediamine.

Raw material consumption quota: nitrobenzene 1400kg/t, nitric acid 787kg/t, sulfuric acid (98%) 780kg/t, iron powder 3083kg/t.Class Toxic Substances Toxicity Grade High Toxicity Acute Toxicity Oral – Rats LD50:280 mg/kg;Oral administration – mouse LD50:67.7 mg/kg flammability hazard characteristics Flame flammability;When heated, toxic aniline gas is released.
