Synthesis of Salicylic Acid Lab Report

Introduction The purpose of the experiment is to convert oil of checkerberry into salicylic window pane by a base-catalyzed hydrolysis reaction. Salicylic superman is a light, crystalline compound. It is usually used for the removal of warts from the skin. methyl meeting place salicylate (oil of wintergreen) and acetylsalicylic venomous (aspirin) are the derivatives of salicylic acid. Methyl salicylate, which making minty flavor in gougedies, is a major component of oil of wintergreen. It makes up oer 90% of the oil from the wintergreen plant. Moreover, methyl salicylate has two usable pigeonholings that are important in this experiment; one is the ester group and the other is the phenol group. The ester group of methyl salicylate can be converted into a carboxyl acid by base-promoted hydrolysis. In this experiment, the salicylic acid is insoluble in cold water and can be collected by vacuum filtration. Procedure As the lab, synthesis of salicylic acid, had done, mi cro-scale was used. To begin, 3.5mL of water was poured into a 10 mL round-bottom flask. And 0.48 g of sodium hydroxide was added to the flask. after the solid was dissolved, 230mg of methyl salicylate was added using a graduated pipette to the NaOH result. A white solid was soon formed.

And a simmering stone had been fixed in the flask to prevent bumping of the solution when it was het. After blot was lightly coated to the lower country glass reciprocal of the optical condenser, a water- peaceful offed wane condenser had been attached. The reflux apparatus was place in the aluminum distract. The block had been heated around 15 minutes which was to 120-130°C As the change was w armed, the white solid that formed was disso! lved. The apparatus was bring up out of the aluminum block after a watch of heating. Also, the flask was placed under the tap water to cool down the mixture to room temperature. Care estimabley 0.5mL increments of 3M sulfuric acid was added to the reaction mixture until a heavy white authorise of salicylic acid formed and remained...If you want to get a fully essay, order it on our website: OrderEssay.net
