Descripción

General description

Ammonia solution is commonly used as a pH-adjusting or buffering agent in a variety of liquid formulations. It also acts as a base in some chemical reactions.

Application

Ammonia solution (7N methanolic ammonia) can be used in the synthesis of:      

• Hydrogen halide salts of primary amines from corresponding halides under microwave irradiation.      
• N-alkylbis(3-aminopropyl)amines by Raney nickel catalyzed hydrogenation of N-alkylbis(cyanoethyl)amines.
• 2-quinoxalinecarboxamide by ammonolysis of 2-methoxycarbonylquinoxaline.

Ammonia solution (7N methanolic ammonia) may be used in the preparation of trioxolanes. It may also be used in the preparation of hydrogen halide salts (HX) of primary amines under microwave irradiation.
