How to purify a carboxylic acid by recrystallisation?Watch
I don't think we have to know it for our spec but in the reaction all we have to know is to heat and reflux slowly to obtain the C.Acid and alcohol. (Heat and reflux when we acid-catalysed hydrolise it).
I found this link if it might help understanding why it maybe difficult to purify; https://www.thestudentroom.co.uk/sho....php?t=4212189
However, you are speaking about base catalysed hydrolysis where the carboxylate salt is formed.
Hence, can we just not liberate it w/dilute mineral acid to obtain the C.Acid but not in crystalline form?
Yeh liberating the c.acid with a dilute acid does make sense, but I was't sure cause I assumed the spec meant base hydrolysis.
There may be another method cause to determine melting points, it has to be a crystal c.acid from recrystallisation first?
