Heat to $\pu{100°c}$: the picric acid gets dissolved. wait : nice yellow needles are produced in the tube by slow cooling. it is picric acid, which can be filtered in case of necessity. but don't do it presently. decant the aqueous solution, and keep the solid in the tube. as picric acid is an explosive stuff when dry, don't dry it and don't.
Pdf Synthesis Of Picric Acid At Domestic Scales Procedure: 1. weigh 4 g of phenol (or take 5.0 ml of liquefied phenol) and place in a 500 ml bottom flask. 2. add 5.0 ml con. sulphuric acid and mix thoroughly. as their action is exothermic, the mixture becomes warm. 3. heat the flask in a water bath for 30 minutes to complete the formation of phenol sulphonic acid.
