Friedel-Crafts Reaction

Name: ID number: 10346597 Experimental Title: Semi-Microscale Friedel-Crafts Reaction Members of radical: conflict: Title: Preparation of 2-(4-Methylbenzoyl) benzoic venereal disease from toluene. excogitation: The social occasion of this experiment is to synthesis 2-(4-Methylbenzoyl) benzoic acid from toluene. Reagent Table: ReagentsRMM (g/mol) tote up used (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 CS262 varlet 48. The act was followed exactly; however one change to the procedure was made during the course of the experiment. A great deal of the yokelish mathematical harvest-home remained in the flask after its collection. To revoke the pass of this product a further 6.5 ml of sodium carbonate was added to the crude 2-(4-methylbenzoyl) benzoic acid. Since it was mostly stuck to the sides of the flask, it was unwrappered and shake in determine to obtain the unhurt crude product. apparatus for the reaction selective information: The product was obtained as a white crystalline solid. 00.0602 grams of the product were obtained.

The boiling crest retch of the pure product was assemble 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 sentence there was an ontogenesis of heat content chloride. The reaction mixture rancid yellow to dark grand to brown, unt il it eventually turned almost black. At thi! s take aim the evolution of gas had begun to stop and the mixture was heated 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 order to elicit off the toluene. When the flask was cooled and the ice added the solid product was a solidified orange...If you want to get a full essay, order it on our website: OrderEssay.net
