WitrynaThe benzoic acid was extracted by the use of base and extraction technique. Then a crystallization was performed in order to separate benzoin by the use of hexane a solvent, leaving the dibromobenzne in the mother liquor. The percent recovery for benzoic acid was 91.8% and 80.3% for the benzoin. WitrynaThe flow chart below outlines a general procedure for separating acidic, basic and neutral organic compounds using the principles of the solubility switch.
