| Hazard Information | Back Directory | [General Description]
A colorless to brownish purple crystalline solid. Toxic by ingestion and inhalation and an irritant to skin and eyes. Soluble in water, alcohol and ether. Decomposes to emit toxic oxides of nitrogen when heated to high temperature. Used in making dyes. | [Reactivity Profile]
3,4-DIAMINOTOLUENE(496-72-0) neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides. | [Air & Water Reactions]
Insoluble in water. | [Fire Hazard]
Flash point data for this chemical are not available. 3,4-DIAMINOTOLUENE is probably combustible. | [Chemical Properties]

Tetrahedron Letters, 42, p. 2277, 2001 DOI: 10.1016/S0040-4039(01)00163-0 | [Synthesis]
A synthesis method of 3,4-Diaminotoluene include that hydrogenation reduction reaction is performed by taking o-nitro-p-toluidine as a raw material under the action of a catalyst and an alcohol solvent to obtain 3,4-diaminotoluene, wherein the weight ratio of the solvent to o-nitro-p-toluidine is (1.5-3):1; and in the hydrogenation reduction reaction, the temperature is 65-85 DEG C and the pressure is 1.0-4.0 MPa. |
