The product from the previous day's experiment will be used as the reactant on the next day's experiment. Stoeger Firearms Catalog, Note: This is not your typical Vacuum Filtration apparatus. Dissolution: Dissolve all the mixture with 40 ml of dichloromethane by swirling it. I chose to use such a large excess for three reasons: After refluxing, filtering and removing the Toluene, HCl is added.

The Toluene layer is the top one and can be discarded. k / is a white (or colorless) solid with the formula C 6 H 5 CO 2 H. It is the simplest aromatic carboxylic acid.The name is derived from gum benzoin, which was for a long time its only source.Benzoic acid occurs naturally in many plants and serves as an intermediate in the biosynthesis of many secondary metabolites. In the first part, the purpose was to find the solubility of the four compounds, anthracite, resorcinol, benzoic acid, and 4-amino-1-napthalenesulfuric acid using three different solvents, water, toluene, and n hexane. Reaction Scheme Mechanism Experimental Benzonitrile (1.0202 mL, 10 mmol) and sodium hydroxide (13 mL, 10%) were combined and refluxed with In a 12-l. flask fitted with stirrer and reflux condenser are placed 600 g. (3.8 moles) of potassium permanganate, 7 l. of water, and 200 g. (1.6 moles) of o-chlorotoluene (Org. Lab Report on the Synthesis and Recrystallization of Aspirin. Benzoic acid is also present in various products including sauces, jams, jellies and candied fruits. (b) If the sample were mixed with benzoic acid (mp 122C), the melting point of the mixture would be below that of acetanilide and the mixture would melt over a large range, perhaps 95- 105C. WebFinally, the wet crystals of crude benzoic acid were recrystallized from an aqueous solution of ethanol [6].

The methyl group of toluene is a side chain in the aromatic ring structure and is oxidized to the carboxyl group in the presence of a strong oxidizing agent. Benzoic Acid from the Oxidation of Toluene | Hobby Chemistry The reaction is very interesting and is a very good way to practice lab skills. Introduction Benzoic acid is a versatile reagent that can be implemented in a plethora of syntheses (e.g. Mix the reagents and heat the flask in a beaker of water warmed to 80-90C, for 10 minutes.
