Using a mixture in the organic solvent,
then simply add NaOH. Two searet layers would be form one after one according ti the density.
The layer would be of phenolate and benzenoate ions which would eventually dissolve into the water. Thena fter collect the layer and then add HCl to ppt it. Then filter it after heating. They both would get easily separated then.

BOTH OF THEM CAN BE SEPARTED USING FERRIC CHLORIDE TEST.
TAKEN 1 ML OF BOTH THE SOLUTION IN TWO TEST TUBES. ADD A FEW DROPS OF FERRIC CHLORDIE SOLUTION TO BOTH TEST TUBES,
THERE WILL BE VOILED COLOURISATION IN ONE TEST TUBE. IT MEANS PHENOL GROUP IS PRESENT IN THIS TEST TUBE
IN OTHER TUBE N ADDING FERRIC CHLORIDE SOLUTION PPTs WILL FORMED INDICATING PRESENCE OF BENZOIC ACID
THANKS
NOTE THAT SODIUM BICARBONATE TEST IS ALSO USED TO DISTINGUISH BETWEEN THE TWO COMPOUNDS SOMETIMES
