Reaction Conditions:
with ammonia;silver nitrate in water at 120; under 760.051 Torr; for 6 h;Temperature;
Steps:
1.2 Step 2: Synthesis of 3-amino-3-methylbutyne
as shown in picture 2,The silver nitrate and the 3-chloro-3-methylbutyne synthesized in Step 1 were successively put into the ammonia solution reactor.Stirring,Cooling to 0°C,Then ammonia is introduced into the ammonia solution reactor,Liquid ammonia temperature is controlled at a thermodynamic temperature T = 25°C,After the ammonia has ended,Insulation reaction for 6 hours,After the reaction is over,Stir in water,Then it is transferred to distillation pot for atmospheric distillation.When the distillation temperature reaches 120°C,Distillation is over,When the circulating water of the ammonia solution reactor is cooled to 30°C,Combine the front, middle and back distillates together and transfer them to the washing kettle.Add supersaturated saline and stand stillLayered,3-amino-3-methylbutyne was obtained (yield 94%, purity 99%);
