SYNTHESIS OF THE PHARMACEUTICAL ASPIRIN (ACETYLSALICYLIC ACID) AIM: The aim for this experiment was to synthesise a small amount of aspirin with salicylic acid as the starting product and sulphuric acid as the catalyst. The product obtained from this reaction will be impure and will need to be purified. This will be done by recrystallization. We will then record the products’ melting point and calculate the yield in order to determine the degree of purity of the aspirin sample. Diagrammatic scheme

A Synthesis of Safrole and o-Safrole W.H. Perkin & V.M. Trikojus J. Chem. Soc. 1663 (1927) HTML by Rhodium No direct synthesis of safrole has been recorded‚ the most recent attempt being that of Baker and Robinson (JCS‚ 1925‚ 127‚ 1424)‚ who distilled the product of the action of silver oxide and water upon gamma-piperonylpropyltrimethylammonium iodide‚ but obtained isosafrole‚ the double bond moving into the position of greater stability.

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

agent for rabies. The rabies virus is enveloped‚ it is covered/surrounded by a covering for protection. The rhabdovirus contains up of a helical ribonucleoprotein core(RNP)‚ and an envelope that is surrounding the viru (CDC‚2011). Eukaryotes have a synthesis process between protein and RNA that forms the ribonucleoprotein. The rabies genome has five protein components: nucleoprotein‚ phosphoprotein‚ matrix protein‚ glycoprotein‚ and polymerase protein(CDC‚2011).
