WebSalicylic acid can be obtained by extraction from these plants, or it can be synthesized from other chemicals. Other starting materials that are needed for the synthesis of acetylsalicylic acid include acetic anhydride, a type of organic compound, and a base such as sodium hydroxide or potassium hydroxide. WebDec 30, 2013 · Standard solutions that are used for extraction are: 5 % hydrochloric acid, 5 % sodium hydroxide solution, saturated sodium bicarbonate solution (~6 %) and water. All of these solutions help to modify the (organic) compound and make it more water-soluble and therefore remove it from the organic layer.

Webwith the acetic anhydride. Thus, salicylic acid is limiting and a maximum of 0.0305 moles (5.50 g) of acetylsalicylic acid can be produced in the reaction (theoretical yield), based on a 1:1 molar ratio of salicylic acid to acetylsalicylic acid in the balance equation. 4. Assume the experiment yielded 3.92 g of product; thus the % yield would be: WebNov 14, 2012 · the combination of salicylic acid and methanol, is also known as the oil of wintergreen. Methyl salicylate was first isolated in pure form in 1843 by extraction from wintergreen plant (Gaultheria). It was soon found that this compound had analgesic and antipyretic character almost identical to that WebExtraction is the technique used to obtain your product form the sample Preparation: ... Objectives: To synthesize methyl salicylate by esterification of acetylsalicylic acid with methanol.
