Usage And Synthesis

Chemical Properties

Off-white small blocks

Uses

5-Methylbenzotriazole intermediate.

Uses

4-Methyl-o-phenylenediamine was employed as chromogenic reagent in the spectrophotometric determination of selenium(IV). It was used in the synthesis of an asymmetrical tetradentate Schiff base via condensation with dehydroacetic acid and salicylic aldehyde.

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.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

3,4-Diaminotoluene 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.

Fire Hazard

Flash point data for 3,4-Diaminotoluene are not available. 3,4-Diaminotoluene is probably combustible.

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.
