N-Methyl-1,2-benzenediamine dihydrochloride Chemical Properties,Uses,Production
Chemical Properties
Redish Powder
Uses
N-Methyl-o-phenylenediamine, Dihydrochloride (cas# 25148-68-9) is a compound useful in organic synthesis.
General Description
Crystals (from ethanol); light purple powder.
Air & Water Reactions
Water soluble.
Reactivity Profile
N-Methyl-1,2-benzenediamine dihydrochloride is an acidic salt. Materials in this group are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
Fire Hazard
Flash point data for N-Methyl-1,2-benzenediamine dihydrochloride are not available; however, N-Methyl-1,2-benzenediamine dihydrochloride is probably combustible.
Synthesis
In a dry reaction flask, N-methylphthalimide was dissolved in methanol and then dilute aqueous hydrochloric acid was slowly added to the reaction flask and the resulting reaction mixture was stirred at room temperature for several hours. Directly after the reaction, the reaction mixture was concentrated under reduced pressure to remove the methanol solvent and water, and the resulting solid was the target product molecule N-methylphthalimide hydrochloride.
