I recently tried to reduce p2np with zinc. This is how I did it:
Into a 250ml erlenmeyer flask was placed 50ml ethanol, 16g p2np and 19g zn. The p2np and zn didn't dissolve, but the flask was swirled until they were finely divided. Then slowly 40ml of 30% HCl was dripped in, drop for drop almost, while the flask was swirled. When the flask got a little hot, it was put into a cooling bath. It was aimed to keep it at about 30C. After all the acid was dropped in, there was still some lumps of zinc left on the bottom, fissing. Probably swirled the flask to little. They were left fissing for an hour. Now the solution was yellow. It was poured into a sep funnel, without the unreacted zinc. 60g NaOH in 200ml water was added. At first much ZnOH precipitated, but after all NaOH was in, most had dissolved again, and there was an yellow/orange oily layer on top. This was separated. It weighed 13g, but was probably unpure. No distillation equipment was had, so the oil was just dissolved in some isopropanol, and 4g of 98% acetic acid was dripped in. This didn't produce any crystalls at all, even after some hours in the freezer.
Some questions:
1. Can't you make amphetamine acetate how I attempted to do it?
2. Was the orange/yellow oil layer really amphetamine?
3. Has anyone got any tips?
