| Hazard Information | Back Directory | [Chemical Properties]
m-Tolidine(also known as 84-67-3 or 2,2''-Dimethyl-[1,1''-biphenyl]-4,4''-diamine) is pink particles and can form prisms when exposed to water. It is soluble in cold water, alcohol, and ether. In the presence of iron(III) chloride, m-Tolidine does not produce any color. It is tetrazotized with nitrite and acid and couples to form dyes.
| [Uses]
M-TOLIDINE is used for preparation polyimide and epoxy resin material.
| [Definition]
M-Tolidine gives no color in the presence of iron(III) chloride. It is tetrazotized with nitrite and acid and couples to form dyes. M-Tolidine was used in the past for the production of azo dyes. | [Preparation]
M-Tolidine is made by the reduction of m-nitrotoluene with zinc dust and sodium hydroxide solution. The subsequent rearrangement is carried out with hydrochloric acid or sulfuric acid and gives rise to m-tolidine dihydrochloride or m-tolidine sulfate, which are isolated as salts. The free base is diffificult to isolate and is therefore not a commercial product.
| [Chemical Reactivity]
M-Tolidine gives no color in the presence of iron(III) chloride. It is tetrazotized with nitrite and acid and couples to form dyes. |
