    simplest way to synthesize an ether is to have an alkoxide react with a primary haloalkane or a sulfonate ester under typical SN2 conditions. The scientist who developed this reaction, Alexander W. Williamson, was a professor at University College in London in the latter part of the 1800's. This reaction has been around a while! Secondary haloalkanes and sulfonate esters are occasionally used in the Williamson ether synthesis but the yields are often poor. The ether prepared in this experiment is...

INTRODUCTION Synthesis Acetylsalicylic acid is an acetyl derivative of salicylic acid which appears as a white and crystalline and a weakly acidic substance with a melting point of 135°C and is also known to be aspirin. It is one of the most widely used drugs that can lower fever and is used as a painkiller. According to (Escobel, 2011), Aspirin is synthesized through the reaction of salicylic acid with acetyl anhydride that causes a chemical reaction that turns salicylic acid's hydroxyl group...
