10 g benzaldehyde + 24 g MEK + 28 g hydroc.acid (~20%) = 28 g of crystals, dried in pyrex dish = 13 g of crystals.
Just keep it simple. When you are done heating, extract the brown organic layer. Wash with 40 ml of water. Extract again. Put 20 ml:s of 10% KOH-solution in. Get rid of the water. Check pH. If too acidic, or too basic, put it to 7. Get rid of the water again. Put it in freezer, because you can then, when frozen, pour the oily shit away, and get almost white crystals. Put the crystals in pyrex dish, or something and dryi it. It can liquify, but no problem. Just heat, freeze, heat, freeze, you dry those crystals, but they cannot be crispy dry. Don't know why. Maybe they are just like that.
