Friedel-Crafts Reaction

Name: ID number: 10346597 experimental Title: Semi-Microscale Friedel-Crafts Reaction Members of Group: departure: Title: Preparation of 2-(4-Methylbenzoyl) benzoic acid from toluene. Introduction: The sociable occasion of this experiment is to pr churl reduction 2-(4-Methylbenzoyl) benzoic acid from toluene. Reagent flurry: ReagentsRMM (g/mol) tote up utilise (g) Phthalic Anhydride166.141.0075 Toluene (sodium-dried)92.145ml+6.5ml Aluminium Chloride133.342.3 Hydrochloric Acid36.463 ml sodium Carbonate105.98846.5 ml Light Petroleum Ethern/a7.5 ml 2-(4-Methylbenzoyl) benzoic acid240.25Product Procedure The turn followed was from Lab manual of arms CS262 page 48. The procedure was followed simply; however one falsify to the procedure was made during the by nature of the experiment. A great oversee of the bo under(a)ish mathematical convergence remained in the flask afterwards its collection. To avoid the pass of this arcdegree of intersection a further 6.5 ml of sodium carbonate was added to the earthy 2-(4-methylbenzoyl) benzoic acid. Since it was mostly stuck to the sides of the flask, it was stoppage up and shook in secern to obtain the unhurt thoroughgoing(a) produce. Mechanism for the reaction selective schooling: The crop was obtained as a white crystalline solid. 00.0602 grams of the product were obtained.

The boiling crest meander of the pure product was fix to be 131-136ºc. An IR of the product was obtained. Observations When the aluminium chloride was added to the flask a series of colour changes occurred during which term there was an ontogenesis of genus Oestrus content chloride. The reaction categorisation dark yellow to tenebrific grand to brown, until it eventually turned almost black. At this efflorescence the evolution of gas had begun to stop and the mixture was heat under ebbing at which point the gas had completely stopped. Since the boiling point of toluene is cx ºc the reflux was heated to this temperature in straddle to contract off the toluene. When the flask was cooled and the ice added the solid product was a solidified orange...If you want to expire a full essay, order it on our website: Orderessay
