Anthony Walker Professor Prinsell 30 September 2021 Melting Point and Recrystallization of Unknown Introduction: Over the course of Toluene is a clear, As benzoic acid and 2-naphthol have similar melting points, accurate and rough temperatures would not help in this case. It is a common undergraduate preparation and an unusual feature of the compound is that its melting point equals its molecular weight (122). 0000005597 00000 n Its classified as a carboxylic acid because it has a carbon group in its structure, which is the COOH group. The liquid is allowed to cool and the benzoic acid which separates, is filtered, washed with a little cold water and re-crystallized from hot water, yielding a final product with a melting point of around 121. The mixture is mixed until a permanent emulsion is formed. Th Although there are many ways to prepare Benzoic acid from Toluene, the simple one may be the following.
