Which option is NOT a meth production phase?

Which option is NOT a meth production phase?

• A. Filtration
• B. Extraction
• C. Reaction
• D. Separation/oil

Answer: (A)

The idea being tested is how we classify steps in a synthesis process versus general lab purification actions. Filtration is a purification technique used to remove solids from a liquid, usually as a cleanup after a reaction or extraction. It doesn’t involve the chemical transformation or the deliberate separation of solvent-related phases that define a production phase. Extraction, reaction, and separation/oil describe stages where the product is formed and isolated: extraction moves compounds into an appropriate solvent to separate them from others; reaction is the actual chemical change turning reactants into the product; separation/oil refers to separating different liquid phases and isolating the desired compound from impurities. Filtration sits outside those core production steps as a cleanup method, not a production phase.
