Procedure
The turn followed was from Lab Manual CS262 page 48. The procedure was followed exactly; however one change to the procedure was made during the course of the experiment. A great deal of the bounderish mathematical product remained in the flask after its collection. To avoid 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 stoppered and shook in order to obtain the unhurt crude product.

Mechanism 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 range 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 time there was an ontogenesis of heat content chloride. The reaction mixture turned yellow to dark grand to brown, until it eventually turned almost black. At this point 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 110 ºc the reflux was heated to this temperature in order to distil 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
