Abstract Using 4.032g of salicylic acid 8.0mL of acetic anhydride on a hot bath the reaction was speeded up by the use of a catalyst phosphoric acid. 0.04g of synthesised aspirin and transfer it to a 25ml beaker. 3.3 Recrystallisation 3
Prepare the synthesized aspirin sample for testing. The purpose of this lab was to learn how to use salicylic acid to make aspirin. The melting point of a compound is the temperature at which the solid is in equilibrium with its liquid. The procedure involved reacting methyl salicylate with sodium hydroxide and sulfuric acid to create salicylic acid. The lab experiment was divided into parts and the synthesis of the aspirin occurred during the first week.

Mix the solution. Experiment Done: Tuesday January 22, 2013 Data Collection and Processing and Conclusion and Evaluation CHEM 123L, Section: 006, Rm: ESC 149 One goal of this course is to introduce you to the record keeping methods used in research labs. Lab Report The average tablet contains about 325 milligrams of acetylsalicylic acid with an inert binding material such as starch. Crystallization will be induced by scratching the glass beaker to create nuclei around which aspirin may crystallize. Contents Page Additionally, techniques were learned to determine the purity of the synthesized organic molecule of acetylsalicylic acid using a back-titration method. �qeI����% Once the sample was then left to dry in the drawer for a week using the melting point apparatus we conducted the purity assessment of the dried sample. 1.2 Background 1 Discover great essay examples and research papers for your assignments.
the market today is Ibuprofen which Aspirin is the most widely used over-the-counter drug in the world. The following components should be contained for each experiment, along with any additional material required by your instructor.

• Title and date The purpose of this lab was to synthesize aspirin, determine the theoretical yield, compare the percent yield to the theoretical yield and test the purity of aspirin by adding Iron (III) chloride to the product. A solid compounds changes to a liquid when the molecules acquire enough energy to overcome the forces holding them together. • Physical data (including calculations) One test will detect the presence of leftover salicylic acid in the synthesized aspirin and allow you to determine its concentration.
Part II. The purpose of this lab was to learn how to use salicylic acid to make aspirin. (2008, 02).
Tuesday February 4, 2013, 2:30pm-5:20pm Its natural form is salicylic acid.
