<<My Answer:The melting point was low and the melting range was so wide because the aspirin partially decomposed.>> this seems reasonable. Was the aspirin allowed to stand in the methanol? What happens if you allow an ester to stand in a large excess of an alcohol? Also what happens if you allow a carboxylic acid to stand in an excess of an alcohol?
<>Therefore, it became impure and caused the melting range to widen.>> Agreed.
<< Due to the partial decomposition, the carbon backbone broke down some,>> you are guessing here!! what are the possible side products?
