Date Experiment conducted: 05/02/2009 Date Report Written: 08/02/2009 Synthesis of Acetyl salicylic acid (Aspirin) Abstract Introduction: The following report contains information on how to produce aspirin. The experiment has been carried out on a small laboratory scale. The experiment starts by combining such chemicals such as salicylic acid and acetic anhydride. The synthesis of aspirin is classified as an esterification reaction. This is a substitution reaction where the alcohol group

Conclusion Micromeritic properties refer to science and technology of small particles. The study of particle size and the arrangement of particles are of significant importance as it affects the physical‚ chemical and pharmacologic properties of a drug. Also‚ it is important for not only manufacturing and packaging but also quality control from raw material to final product uniformity. The science of micromeritic involves the study of particle size‚ size distribution‚ flow properties and bulkiness

coursework I have been investigating the synthesis of Aspirin and checking for presence and purity of Aspirin. Throughout this coursework we have looked at the history of Aspirin; industrial manufacturing; making salicylic acid; the preparation of Aspirin; recrystallization and purity; melting point; thin layer chromatography (TLC) and titration of Aspirin. I’ve learned a lot about Aspirin‚ how it works and how it is made. We found out that the Aspirin we made and used was actually very pure when we

The Purity and Purification of Solids Melting Point Lab Introduction: The point of this lab was to determine the eutectic point for the naphthalene biphenyl mixture‚ as well as determining the melting point of an unknown substance by comparing it with two known samples. Melting point is a temperature in which a substance changes from solid state to liquid state. Melting points are used to determine whether the given substance is pure or not. Substances that melt sharply‚ less than 1-2°C indicates

CM1191 Experiment 5 Kinetic Studies on the Decomposition of Aspirin Aims To investigate the molar absorptivity of salicylic acid To determine the concentration of dissolved aspirin in heated water at various times To determine the effective rate constant of the decomposition of aspirin in heated water at 85°C. Results and Discussion The molar absorptivity of salicylic acid‚ ε‚ can be calculated from the equation‚ A = εcl. A more accurate value can be obtained by finding the gradient of a graph

“The Ganga‚ especially‚ is the river of India‚ beloved of her people‚ round which are intertwined her memories‚ her victories and her defeats. She has been a symbol of India’s age-long culture and civilization‚ ever changing‚ ever flowing‚ and yet ever the same Ganga‚” (Jawaharlal Nehru). Spoken by the First Prime Minister of India‚ this quote summarizes the importance of the Ganges River. The Ganges‚ one of the holiest rivers in the country‚ functions not only as a source of agriculture‚ energy

Synthesis of Aspirin and Oil of Wintergreen Janelle Alyssa P. Prudente De La Salle University-Dasmariñas Dasmariñas City‚ Cavite‚ Philippines ABSTRACT In this experiment‚ acetylsalicylic acid commonly known as aspirin and methyl salicylate‚ commonly known as oil of wintergreen‚ was synthesized from salicylic acid. This study will show that it is possible to show two very different organic compounds from the same common starting material. For the synthesis of aspirin‚ salicylic acid
