    Steam P2P Distillation as a Purification Method

    Introduction Phenylacetone (P2P) is a key-reagent for a methamphetamine synthesis and can be used for an amphetamine manufacturing as well. Our experiments have clearly showed that P2P purity have direct impact on the methamphetamine synthesis yield and its purity [via sodium borohydride (NaBH4)...
