Mixtures have (higher/lower) melting points than pure substanceslower What is the purpose of sodium acetate solution in the amide synthesis of acetophenetidin?In the acylation reaction, the amine acts as a nucleophile, but we have the ammonium salt present in our solution. This ammonium salt can't act as a nucleophile (it doesn't have non-bonded electrons to use), so we need to add something to deprotonate the ammonium salt. This is the purpose of the sodium acetate - it is just a wea...
