Darnell Shaw Lab Extra Credit Hippocrates of Cas (460-377 B.C.)‚ The Healer‚ noted that chewing leaves of willow (Salix) reduced pain‚ and he prescribed this remedy for women in labor. The Healer certainly did not discover this drug‚ which was used for centuries earlier in European folk medicine. Ancient Egyptians took an infusion of dried myrtle leaves to treat muscle pain. The myrtle leaves were also found to contain salicylic acid. Two Italians‚ Brugnatelli and Fontana‚ had in fact already

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 for

FOUNDATION IN SCIENCE INTRODUCTION TO PRACTICAL ORGANIC CHEMISTRY – MAKING AND PURIFYING ORGANIC COMPOUNDS Stage 1 – Deciding how much reagent to use Most organic reactions do not go to completion; most reach an equilibrium position with significant quantities of reactants still remaining. In addition‚ separating the desired product from the rest of the reaction mixture‚ and then purifying it‚ will result in the loss of more of the product. The amount of product obtained expressed as a percentage

If someone was assigned to compile a video of clips that would make me cringe‚ they would come up with something similar to The Purity Myth. The clips used were reminders of the oppressive‚ heteronormative‚ misogynistic system that I grew up in. The film itself provides ample examples of the ways in which women’s sexualities are policed‚ the idealization of virginity‚ the shortcomings of abstinence only sex education‚ and the arguments against women’s reproductive health. I have never been envious

the Percentage of 2-ethanoylhydroxybenzoic Acid in an Aspirin Tablet Introduction and Aim: An Aspirin tablet is an analgesic; therefore the purpose is to relieve pain and due to it also being an antipyretic its other tenacity is to lower the body temperature. An experiment was carried out on the basis of calculating the percentage of 2-ethanoylhydroxybenzoic Acid in aspirin tablets hence 4 commercial tablets were taken to determine its purity using a known volume of standard sodium hydroxide‚ due

It should stress the information of little side effects compared to other analgesic medicine. Both the retail price and the trade price should be lower than Tylenol. Segmentation and targeting: Datril should target on aspirin users. Datril potential clients could be 1) people currently using aspirin 2) people currently
