few things
bunsen burner cant accurately spread the heat
also it uses methane (gas) which could disturb results
and finally .. it would take too long to get the heat up to 300-400 degrees
probz got it wrong

I just thought logic and said it is hard to keep a stable temperature of the bunsen burner while the alcohols condense.
