Answer :
The synthesis of trans-p-anisalacetophenone involves the following chemicals: p-anisaldehyde (reactant), acetophenone (reactant), 95% ethanol (solvent), and 40% sodium hydroxide (catalyst). Their purpose is to react and form the desired product, trans-p-anisalacetophenone, through a condensation reaction.
The melting point of trans-p-anisalacetophenone is 56-58°C (source: Sigma-Aldrich) and its molar mass is 210.25 g/mol (source: PubChem).
The procedure includes mixing reactants, using ethanol as solvent, adding sodium hydroxide to catalyze the reaction, and allowing the mixture to sit at room temperature. Crystals are then formed, and the product is collected using vacuum filtration. Impure product is recrystallized using hot ethanol and water, and the pure product is obtained by cooling and filtration. The product's melting point is determined, and an IR spectrum is obtained for analysis.
