Chemie und Industrie

Anwendungen

VerwendenM-TOLIDINE is used for preparation polyimide and epoxy resin material.

Darstellung · 1 Eintrag

synthetischeM-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.
