Recrystallizing Sodium Acetate from solution
The Purification of Laboratory Chemicals by Perrin and Armarego states about sodium acetate this procedure:


  Cryst[alise]d from acetic acid and pumped under vacuum for 10h at 120$^\circ$. 
  Alternatively, cryst[alise]d from aqueous EtOH, as the trihydrate. This material can be converted to the anhydrous salt by heating slowly in a porcelain, nickel or iron dish, so that the salt liquefies. Steam is evolved 
  and the mass again solidifies. Heating is now increased so that the salt melts again. (NB: if it is heated too strongly, the salt chars.) After several  minutes, the salt is allowed to solidify and cooled to a convenient 
  temperature before being powdered and bottled (water content should now 
  less than 0.02%).
