Helpful? This question is too broad, because it depends on the procedure you used, and also whether you're talking about the reaction itself or the recrystallation. Elizabeth Ajasa In this experiment, the Oil of Wintergreen is put into an Erlenmeyer flask containing sodium hydroxide to create sodium salicylate. Introduction: 1. Suveda Perikala This, could have occurred when stirring the salicylic acid, acetic anhydride, and phosphoric, acid in the Erlenmeyer flask, which was sitting in boiling water. The amount of each compound should be the same because there is a 1:1 ratio between them. Erlenmeyer flask containing sodium hydroxide to create sodium salicylate. (Acetylsalicylic Acid)

Some materials may have been lost during a couple of the, steps, causing the percent yield of the aspirin to be less than it should have been. You're not in freshman lab any more.

Aspirin originated from the bark of a White Willow Tree. Synthesis of Aspirin from Oil of Wintergreen Premium Our theoretical yield was calculated to be 5.22 g. Therefore our % yield was determined to be 80.6%. Kenneth Ivan P. Durano Summary: To purify the crude product by Recrystallization.

The store bought aspirin turned a milky, purple when ferric chloride was added and the synthesized aspirin turned a light purple, when ferric chloride was added, whereas the salicylic acid turned an eggplant color when, ferric chloride was added to it. The Synthesis of Organic Aspirin ABSTRACT: The purpose of this experiment was to find out how a reaction undergoes for a globally known painkiller called aspirin, and to become familiar with achieving successful yields. 3  Pages. Without the addition of the acetyl group, salicylic acid is an irritant to the gastro-intestinal (GI) tract.

objective was to convert a specific amount of salicylic acid into the same amount of aspirin that was high in purity. The present experiment will be the synthesis of a familiar organic compound called aspirin. 7  Pages.
