About this document
Extraction of Benzoic Acid and Phenanthrene by lklepo is a document available to read on EtoBox.
1. The document describes an experiment to separate a mixture of benzoic acid and phenanthrene using liquid-liquid extraction. It involves dissolving the mixture in methylene chloride and extracting with sodium hydroxide solution, which forms water-soluble sodium benzoate. 2. After acidifying the aqueous layer, benzoic acid precipitates and is collected by vacuum filtration. The organic layer is dried and evaporated to yield phenanthrene. 3. Key steps include multiple extractions of the organic layer, dete
