Acetaminophen Abstract: The aim of this experiment is to prepare Acetaminophen (p-acetamidophenol)‚ an amide. Acetaminophen will be created by treating an amine (p-aminophenol) with an acetic anhydride. Color impurities present in the solid acetaminophen will be removed and then the decolorized product will be collected on a Büchner funnel for further purification by crystallization. Purity will then be determined by melting point. Introduction: Acetaminophen is commonly used as an analgesic to

acetic acid. Boil mixture for 30 minutes. Add the phenylhydrazine solution through the condenser. Remove from the hot plate. Rinse with 5 mL of 1:1 mixture of water and glacial acetic acid to complete the transfer of phenylhydrazine. When a yellow solid emerges‚ swirl the mixture. Wrap a dry cloth around the flask. Cool to room temperature (preferably overnight). Filter off osazone. Press and drain it. Wash with a cold mixture of 10 mL each of water and ethanol. No need to dry the product for the

United States believe that America has been struck with a "trash crisis"‚ however‚ this is not truly case from the recent Environmental Protection Agency (EPA) facts for 2010. Before‚ we start let us take a moment to discuss what trash or municipal solid waste (MSW) is. MSW is the collection of commonly used items that discarded by the general populace‚ many of these include packaging‚ food scraps‚ grass clippings‚ sofas‚ computers‚ tires and house appliances (EPA).

There are only five platonic solids and the name of each shape comes from the number of faces it has.The five platonic solids are tetrahedron‚ octahedron‚ cube‚ icosahedron‚ and dodecahedron. Each solid is made of regular polygons and the polygons of each solid are congruent. The topics that will be discussed in this paper are what are the five platonic solids‚ who classified the five shapes‚ their key features‚ the shapes similarities and differences‚ and examples in real life.

Managing our Solid Waste: An Overview of the Ecological Solid Waste Management Act Much had been written about the worsening problem of solid waste in Metro Manila and other urban centers in the country. Even more were fora‚ seminars and conferences conducted to discuss ways of solving the problem. For how long would it take us to attain a zero waste economy‚ no one knows. But‚ one thing is sure - time is running out and WE need to act NOW! Why WE? The answer is simple‚ but at the same time
