    Aspirin And Plants What is Aspirin? Acetylsalicylic acid, commonly known as aspirin, has a chemical formula of C9H804. Aspirin is one of the first drugs in the world that came to a common use with about 35,000 metric tons that are annually used and consumed by people all over the world. Aspirin is commonly used to relieve people from pain of headaches and reduces the temperatures of fevers. Aspirin is also used to sooth a scratchy throat, relieving pain from bug-bites, wiping away rust

    Synthesis and Characterization of Aspirin (Acetylsalicylic Acid) Summary The purpose of the Aspirin lab is to synthesis the Acetylsalicylic acid which is known as aspirin and calculate the limiting, theoretical, and the melting point. In the second step, the Theoretical yield came out to be salicylic acid seeing it was the smallest out of the phosphoric and acetic anhydride. Experimental melting point-The literature melting point was 138-140 Celsius, when it was prepared in lab, it started melting

    In this experiment, two organic esters, aspirin or commonly known as acetylsalicylic acid and methyl salicylate (oil of wintergreen) were synthesized through an esterification process and then the purity of some of the molecules was determined through analytical techniques. During part one of this experiment, aspirin was synthesized. Salicylic acid and acetic anhydride were mixed to produce acetylsalicylic acid (aspirin). Typically, acetic acid is used but the reaction with acetic acid is slow

    During 1915 World War I the British required aspirin nonetheless it was prepared by the Germans (Co &Bayer). Thus the British government presented a £21,000 return to anybody who could improve a practicable developed method. This was attained by George Nicholas, a pharmacist in Melbourne, who consequently provided his pill the name Aspro. 1995s More than 10~12 million kilograms of aspirin are prepared in the US every year. Today aspirin is not just only used as a drug then has also been planned as

    CHARACTERISTICS OF ASPIRIN- ACETYLSALCYLIC ACID Summary: The lab experiment was divided into parts and the synthesis of the aspirin occurred during the first week. 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. 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. Introduction: Aspirin (acetylsalicylic acid)

    Introduction Aspirin is a widely name used to refer to a chemical compound known as acetylsalicylic acid. It is commonly used as a pain killer. Salicylic acid is extracted from the bark of willow plant. In the past, the bark willow plant was used as the remedies for tonics and headache. Currently, salicylic acid is administered to patients in aspirin form which is less irritating to the stomach as compared to salicylic acid. Aspirin is synthesised by reacting excess acetic anhydride with the salicylic

    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. Hypothesis: I hypothesize that salicylic acid will react with acetic anhydride to produce acetylsalicylic acid (aspirin) and

    6th, 2014 Experiment 5: Synthesis of Aspirin Abstract: In today’s experiment, aspirin was synthesized using salicylic acid, acetic anhydride, a catalyst (concentrated sulfuric acid), and water. The main goal of this experiment was to synthesize pure aspirin. Another goal was to test aspirin’s purity by running a TLC and getting a melting point test done. Also, calculations of the theoretical yield and percent yield were done. The final product (aspirin) percent yield was 18.247% yield Introduction:

    associated theoretical value due to the overall percent yield, which will be discussed further. Also, according to the same calculations made in calculation #1, the calculated mass for Bayer Aspirin was inaccurate as the calculated value was less than what was said by the company. In other words, the Bayer Aspirin did not contain 325mg of ASA, instead it actually contained 283mg. The percent purity of ASA was calculated to be 65.0 % and based on the reaction table, the limiting reagent was salicylic

    What is Aspirin? Aspirin is on of the first drugs to ever be commonly used and is still one of the most widely used in the world. How widely used you ask? Approximately 35000 metric tonnes are produced and consumed every year. Chemically aspirin is known as acetylsalicylic acid with the chemical formula of C9H8O4. Aspirin is an analgesic, anti-inflammatory, antipyretic, and is an inhibitor of platelet aggregation. The history of Aspirin Aspirin has been a major part of just about everyone's
