Add two boiling chips and reflux the mixture at a gentle boil for 15- Place 3.00 g of salicylic acid in a 125 ml Erlenmeyer flask. WebSynthesis of benzoic acid (Oxidation of toluene) Random Experiments Int. To the crystalline paste (potassium benzoate) separating out, water is added until a clear solution is obtained from which benzyl alcohol is extracted by repeatedly shaking with ether. Please be safe on your ventures in the wonderful world of Chemistry! If you wish to keep yours, add it to a flask with water. Acid nitrobenzoic acid Allow the mixture to cool and stir occasionally. Open navigation menu. Isolation and Purification of Benzoic Acid After phenyl magnesium bromide is prepared, it is poured over powdered Dry-Ice (solid CO 2) to obtain the bromomagnesium salt of benzoic acid. Include an "Experimental" section as usual, including all spectroscopic and chromatographic data. The mixture was allowed to reflux for about 2,5 hours. WebGive the m.p.
