Acetylsalicylic Acid (Aspirin) Synthesis Telow‚ AJV Sumicad‚ CJ‚ Tavanlar‚ EMMT‚ Chem 40.1‚ Institute of Chemistry‚ University of the Philippines Los Baños I. Introduction Organic synthesis is the process where a desired organic compound is constructed or prepared from commercially available materials. The objective of organic synthesis is to design the simplest synthetic routes to a molecule. Aspirin‚ also known as acetylsalicylic acid is as salicylate drug often used as analgesic

were liquid‚ oily‚ and it had a banana smell. Introduction Artificial flavoring is commonly used in the food that we eat today. For example‚ fruit flavoring is a chemical mixture that mimics a natural flavor as that of banana flavor from the synthesis of isoamyl acetate. Ester is the functional group‚ which is responsible for the distinctive odor and taste that artificial fruit flavoring has. Esters are derived from carboxylic acids. A carboxylic acid contains the –COOH group‚ and in an ester

higher than have been found in other studies‚” says Jon Dobson‚ who studies magnetic nanoparticles in biomedicine at the University of Florida and was not involved in the study. There is a chance the high levels were from accidental contamination in the lab‚ in spite of the researchers’ careful steps to avoid it‚ he says. But if the high levels are simply due to the patients being exposed to high levels of pollution‚ future studies involving a control group from less polluted areas could confirm the

SYNTHESIS AND CHEMISTRY OF K2S2O8 ABSTRACT In this experiment‚ a sample of K2S2O8 was prepared by the electrolysis of an aqueous solution of H2SO4 and K2SO4. The peroxodisulfate anion‚ S2O82-‚ was also observed for its ability to serve as a counterion for precipitation by preparing a copper (II) complex by reacting hydrated copper (II) sulfate with ammonium peroxodisulfate in the presence of pyridine. This same ability‚ coupled with its strong oxidizing ability allowed for stabilization of

taken‚ and finally calcium chloride was added‚ which formed a chemical reaction. Our lab question was how does the amount of calcium chloride affect the temperature of the product? We chose our independant variable to be the amount of calcium chloride added to the water/baking soda mixture. We had the dependant variable be the ending temperature. My hypothesis is IF we add more calcium chloride‚ THEN the temperature of the product will rise‚ BECAUSE the calcium chloride is what releases the gas when

Restaurants are like riddles‚ hard to see through and hard to figure out. In-N-Out is definitely one of these restaurants. Characteristics such as simple with not very much detail‚ make the customer intrigued in seeking the secrets within. What secrets may you ask. To start‚ the restaurant is popularized‚ being full at every hour of the day‚ but what makes people come back‚ why is it when many think of a hamburger they think of In-N-Out? This secret leading to the basic thing every restaurant needs: consumerism

For my paper on the movie Boyz N the Hood as well as the reading Black Freedom Fighters in Steel‚ I will find a common theme that is used in both and explain how they used that theme in their work. The common theme that I found that was used in both the movie and the book is how the characters dealt with the oppression that was in their lives. The characters from the movie Boyz N the Hood that I will be referring to are Doughboy‚ Officer Coffey‚ and Shalika. The characters that I will be using

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. Aspirin is synthesized from salicylic acid and acetic anhydride. Those two chemicals are mixed together along with sulfuric acid to form a crude solid. Filtration is used separate the impurities from the crude aspirin. To get purified aspirin‚ the precipitate was heated until all
