Scheme 1โ€‹

Reagents and materials

  • 49.6 g MDA*HCl + 300 ml H2O
  • 30 g NaOH + 300 ml H2O
  • 800-1000 ml DCM
  • 2-5 g Al2O3
  • 150-200 ml Petroleum ether
  • Flasks
  • Beakers
  • Reflux
  • Separating funnel 2000 ml
  • Heating mantle
  • pH-indicator paper
  • Filter paper
  • HCl gas
  • Distillation setup
  • Vacuum filter

Extraction of Free Baseโ€‹

A solution of alkali in water is prepared in advance and cooled to room temperature. Fig 1

DCM is added to the solution in portions until the layers are clearly separated. If the layers are not separated well, can be adding 400 ml of water and then DCM again. The mixture is mixed well. Fig 5โ€‹

MDA Hydrochloride Formationโ€‹

The formation of MDA hydrochloride from the free base proceeds according to Scheme 2

Scheme 2โ€‹

An additional 20 ml of petroleum ether is added to the filtered solution. Saturation with hydrogen chloride is carried out, with petroleum ether periodically added to replace the evaporating one. Fig 13โ€‹

I hope you make a video of all your work so it can be a reference for us.

Thank you
