O C CH 3 C O O OH H H H H Figure 1 Acetylsalicylic acid (aspirin), C9H8O4 Aspirin (acetylsalicylic acid) is a versatile drug that is consumed in huge quantities worldwide. It is a non-steroidal anti-inflammatory drug (NSAID) with a wide range of physiological effects. AtFile Size: 37KB. Learn aspirin synthesis with free interactive flashcards.

    Aspirin is the single most manufactured drug in the world. Aspirin’s chemical name is acetylsalicyl-ic acid, and it is synthesized from the reaction of acetic anhydride with salicylic acid in the presence of phosphoric acid as a catalyst. The by-product is acetic acid (Figure ). → H 3 PO 4 acetic anhydride salicylic acid aspirin acetic acidFile Size: KB. Aspirin is actually a naturally occurring compound, which can be derived from the bark of willow trees. Native Americans would chew the bark or grind it into a powder to ingest to relieve pain. As obtaining this drug from willow bark is not practical for the wide scale on which it is used, synthesizing the same compound in a laboratory is a.

    Arthur Eichengrün (13 August – 23 December ) was a German Jewish chemist, materials scientist, and inventor. He is known for developing the highly successful anti-gonorrhea drug Protargol, the standard treatment for 50 years until the adoption of antibiotics, and for his pioneering contributions in plastics: co-developing (with Theodore Becker) the first soluble Alma mater: RWTH Aachen University.

SYNTHESIS OF ASPIRIN (acetylsalicylic acid) Place g ( mole) of salicylic acid in a mL Erlenmeyer flask. Add 5 mL ( 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.

aspirin product as well as a commercial aspirin tablet will be compared to a standard % ferric-salicylate solution. In the presence of moisture, aspirin may decompose (hydrolysis) into salicylic acid and acetic acid.

This reaction is the reverse of the synthesis reaction. The maximum allowable amount of. Aspirin Synthesis and Analysis Revised: 12/13/14 • Crush an aspirin tablet and place in a labeled, pre-weighed vial or test tube. Record the mass of the aspirin tablet. Do not lose this container or its contents, you will use them later.

• Take a small amount of the aspirin tablet and dissolve as much as you can in 3 drops of ethyl Size: KB. 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. An experiment is described that is suitable for the early portion of the laboratory in a general chemistry course and integrates organic examples.

It is the two-step synthesis of aspirin starting from oil of wintergreen. The mechanism for this synthesis provides Synthesizing Aspirin book of three major classes of chemical reactions: hydrolysis, condensation, and proton by: Aspirin, also known as acetylsalicylic acid (ASA), is a medication used to reduce pain, fever, or inflammation.

Specific inflammatory conditions which aspirin is used to treat include Kawasaki disease, pericarditis, and rheumatic fever. Aspirin given shortly after a heart attack decreases the risk of death.

Aspirin is also used long-term to help prevent further heart attacks, ischaemic Pregnancy category: AU: C, US: N (Not classified yet). ment (synthesis of aspirin masses, theoretical yield, percent yield and error, and TLC analysis).

After synthesis and analysis, it will be deter-mined if the crude and recrystallized samples were composed solely of either salicylic acid, acetylsalicylic acid, or a combination of both (3).File Size: 2MB. Aspirin is a drug that is usually used to relieve minor aches and pain and other medical uses such as anti-inflammatory medication.

Aspirin is an ester that has high molecular weight and it not soluble in water hence the solid can be separated by crystallization process. Synthesis of Aspirin is known as esterification.

Acetylsalicylic acid, also known as aspirin, is one of the most widely used medications to reduce fever and is also used as a pain killer.

It is an acetyl derivative of salicylic acid. It is a white, crystalline, weakly acidic substance which melts at °C. Aspirin is synthesized through the reaction of salicylic acid with acetyl anhydride Author: Esobel. Aspirin is the most widely used over-the-counter drug in the world.

The average tablet contains about milligrams of the active ingredient acetylsalicylic acid combined with an inert binding material such as starch. This video briefly presents the history, chemistry and function of aspirin whilst synthesizing it.

GrrlScientist Tue 25 Jan EST First published on Author: Grrlscientist. Percentage yield is worked out by Actual yield of synthesised aspirin: 0. g 0. * = 29 Percentage yield: 29% Melting Points CompoundBegan Melting (°C)Totally Melted (°C)Range (°C) Pure Aspirin Crude Aspirin Product from Willow Bark The documented melting point for pure aspirin is °C.

Medicine Analysis – Synthesising Aspirin results After recrystallisation differences between the crude and purified aspirin were noted.

The impure (crude) aspirin was powered and fluffy with small clumps and was slightly yellow in colour whereas the pure aspirin has a less fluffy crystalline powder and was whiter. Using the amount of limiting reactant, she calculated the mass of aspirin that should form as g.

When she weighed her aspirin product on the balance, its mass was g. Calculate the percent yield for this synthesis. Synthesis of Aspirin Learning Goals 1. To synthesize aspirin from salicylic acid and acetic anhydride.

To purify the crude product by Recrystallization. Introduction Most drugs are chemical compounds which are described as "organic compounds" because they are comprised primarily of the elements carbon, hydrogen and oxygen. Aspirin: some background. Patented by Bayer in. One of the oldest drugs. One of the most consumed drugs (Production in the US is 10 million Kg/year) Aspirin: Biological activity.

Aspirin became commercially available in and today it is estimated that over a trillion aspirin tablets have been consumed by those in need of its curative effects. In this experiment aspirin was synthesized from salicylic acid and acetic anhydride.
