WebReacting salicylic acid with acetyl chloride would give you aspirin (acetylsalicylic acid), but would yield hydrogen chloride gas as a by-product instead of acetic acid as the by-product … WebRecrystallization, also known as fractional crystallization, is a procedure for purifying an impure compound in a solvent. The method of purification is based on the principle that the solubility of most solids increases with increased temperature. This means that as temperature increases, the amount of solute that can be dissolved in a solvent ...
