Synthesis and Characterization of Aspirin Courtney Crowe C127Jordan Worcester27 March 2015Synthesis and Characterization of Aspirin Objective:Aspirin was synthesized from salicylic acid and acetic anhydride. Multiple tests were then preformed to determine how pure the sample was. Introduction:Â Â Â Â Â Â Â Â Aspirin was formerly made from willows bark found by Ancient Egyptians. In fact, Hippocrates gave women willow bark to.
Soil Stabilisation Problems in lime and cement stabilized soilsSulphate attack leads to formation of ettringite which causes up-heaving in the stabilized soils due to volume change. Therefore, before the application of cement and lime stabilization techniques, the nature of sulphates present in the soils, soil–lime reactions, mechanisms involved in ettringite formation (delitritious reaction) and its.

Discussion Case Essay Preview: Discussion Case Report this essay Discussion: The performed experimentation resulted in only 0.027g of dibromocholesterol collected as the product, while the theoretical yield was calculated to be 0.2543g. The percent yield calculated was therefore extremely low, at 10.6%. The low experimental yield is likely due to the age of the bromine.
Nitration of an Aromatic Ring Essay Preview: Nitration of an Aromatic Ring Report this essay IntroductionElectrophilic Aromatic Substitution (EAS) is an organic reaction in which an electrophile substitutes a Hydrogen atom in an aromatic compound. It is very useful because substituted aromatic rings are often used as solvents and as important intermediates of many syntheses..
