    Synthesis of Aspirin Ling Tecson Gamido‚ Mitchiko Mariel M. Mizukami Abstract Acetylsalicylic acid‚ or also known as aspirin is known to be a drug that relives people of pain and is commonly used even today. It is synthesized from salicylic acid and ethanoic anhydride‚ both of small quantities. Phosphoric acid was used as a catalyst in the synthesis to speed up the process. Esterification is involved and the final product is aspirin with the presence of acetic acid as the byproduct. In order

    expected melting point. After its temperature reached the plateau‚ the temperature increment was set at 1°C per minute‚ and the melting point range of 152°C-154°C was recorded. After standardizing the melting device‚ a small sample of unknown carboxylic acid was placed in a capillary tube‚ and an arbitrary plateau of 200°C was set. When the sample started to melt at 150°C‚ another capillary tube containing a small amount of unknown sample was placed in the melting device‚ and the plateau was set to 135°C
