The new meth ingredients were, however, more toxic. Phenylacetic acid from Benzyl Cyanide [2] In a silica basin of about 35 cm. -- Benzyl chloride or benzyl bromide;-- Sodium cyanide or acetic anhydride; • Shift to P2P production, but metal hydrogenation process still used • Large seizures of acetic anhydride, benzyl cyanide, sodium ethoxide, thionyl chloride, and tartaric acid MEXICO • Precursors predominately from Asia • Methylamine and P2P are key chemicals • Increasing use of uncontrolled precursors to produce needed chemicals This substance is used in the manufacture of methamphetamine and amphetamine, where it is commonly known as P2P. Both are hydrolyzed to phenyl-2-propanone with dilute hydrochloric acid. The synthesis of P2P from benzyl cyanide involves the manufacture of APAAN prior to the final synthesis of P2P. 2 faradays per mole of benzyl chloride), the remaining benzyl chloride, the toluene which is a byproduct of the reduction of benzyl chloride, and phenyl-2-propanone, both in free form and in the form of its enol acetate, are present in the solution. 7g, 0.
