Preparation and melting point of Aspirin Aspirin is a painkilling drug and is produced worldwide to reduce and stop pain.Aspirin is made up of ehtanoylation of 2-hydroxbenzenecarboxylic acid in a presence of phosphoric acid. AIM: The aim of the experiment is to prepare and produce aspirin as pure as possible. I will do this threw preparing the aspirin and purifying the product threw.Aspirin is a human-made, synthetic version of salicylic acid, used to reduce fever and inflammation and relieve pain. Originally sold as a powder, and now in tablets, aspirin was a trademarked name until 1921.For preparation of Aspirin, acetic anhydride is added to the measured amount of salicylic acid. Sulphuric acid is added and heated for a short period to complete reaction. Water is added once removed from heat with addition of cold water and suction filtration is carried out. As for recrystallisation of aspirin, collected crude product prepared.
The Synthesis of Aspirin Chemistry Standard Level Lab Report Data Collection and Processing and Conclusion and Evaluation Date: December 8th, 2011 Purpose: 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.
SYNTHESIS OF ASPIRIN (acetylsalicylic acid) Place 2.0 g (0.015 mole) of salicylic acid in a 125-mL Erlenmeyer flask. Add 5 mL (0.05 mole) of acetic anhydride, followed by 5 drops of conc. H 2 SO 4 (use a dropper, H 2 SO 4 is highly corrosive) and swirl the flask gently until the salicylic acid dissolves.; Heat the flask gently on the steam bath for at least 10 minutes.
In this experiment, we conduct the synthesis of aspirin, reinforce the skills of recrystallization and the technique of melting point determination. The procedure goes as follows: Weigh 2.4g of salicylic acid in a conical flask. Then add 6mL of acetic anhydride to the acid. Add 3-4 drops of conc. s.
Synthesis of Aspirin By: Jon Torre Purpose: To determine which of four catalysts yields the fastest reaction rate in the acetylation of salicylic acid (1) to form acetylsalicylic acid (2). Reactions: Procedure and Results: Aspirin Synthesis Tap water was heated on a steam bath in a 250 mL beaker. The temperature of an alcohol thermometer was equilibrated in a beaker of room temperature tap water.

As for recrystallisation of aspirin, collected crude product prepared in preparation of aspirin which is impure is dissolved in ethanol and hot distilled water is added to the solution. Once solid dissolved, weigh the watch glass and filter paper, use the filter paper to carry out suction filtration, place crystals on watch glass, weigh the dried crystal and calculate the weight of the aspirin.

PREPARATION OF ACETYLSALICYLIC ACID (ASPIRIN) BACKGROUND One of the most widely used nonprescription drugs is aspirin. In the United States, more than 15,000 pounds are sold each year. This is not surprising when one considers the medicinal applications for aspirin.
The Purity Of Prepared Of Aspirin Biology Essay. Biology Send article as PDF. To synthesize the drug aspirin, the purity of prepared of aspirin is determined by a chemical test. In addition, the percentages of aspirin made are determined. Preparation of aspirin.
Synthesis and Characterization of Aspirin Purpose The purpose of this lab was to synthesize Aspirin and measure the synthesized Aspirin’s purity. By calculating the theoretical yield based on the original amount of Salicylic acid, one could determine the actual yield percentage of the reaction.
The Story of Aspirin Introduction. In the last 30 years medicines prescribed by doctors have changed beyond all recognition. Our better knowledge of the nature of diseases and their management has led to the replacement of many old remedies by new ones specifically designed for each illness.
