Ammonia → 1-Naphthylamine

Participants

Reaction Steps

In a 200-ml autoclave were placed 28.3 grams (0.115 mole) of anydrous potassium 1-naphthalene sulfonate, 9.7 grams (0.241 mole) of sodium amide and 105 ml of liquid ammonia in the same manner as in Example 1. The resultant mixture was heated at 110° C for 10 hours. The reaction pressure in the autoclave was 75 atm. during the reaction. After the ammonia was removed, 10 ml of water was added to the reaction mixture for hydrolysis. The product was extracted with ether and the ether was distilled off to produce crude 1-naphthyl amine. Recrystallization from ethanol gave 14.3 grams of 1-naphthyl amine having a melting point of 48° to 49° C. Yield ws 87.0%.
