Salicylic acid

There is a myth that head lice only affect the poor or uneducated children. This is furthest from the truth, these creatures affects everyone regardless of the socio-economic status of the family. Lice are transmitted from individual to individual, and are not preventable. Once they grasp onto the scalp, the female lice reproduce an average of ten new eggs daily. There are various ways to treat this condition with vinegar and Listerine with a proven track record of eliminating these annoying pests

Aspirin is a widely known medicine used by various people for pain relief. Pain relief is the typical use for aspirin. The aspirin also features has anti-inflammatory properties that can help with several ailments. It also has other properties that can help with other ailments. The US Food and Drug Administration website says that aspirin can be beneficial to populations with cardiovascular disease. When populations use aspirin on the daily, it could lower the chances of a heart attack and other

Acetylsalicylic acid is the active pharmaceutical ingredient that is found in aspirin and is used to treat inflammation, pain and fever. It is created by an esterification reaction of salicylic acid with acetic anhydride in the presence of an acid catalyst. At the end of the reaction, a product and unreacted salicylic acid and acid catalyst was created. The product contains impurities, such as acetic anhydride and salicylic acid, which needs to be removed. Crystallization, a technique used to purify

The purpose of experiment four was to synthetically prepare a sample of salicylic acid from methyl salicylate, also known as wintergreen oil. The salicylic acid formed is to be compared to salicylic acid synthesized from benzene and determine whether or not the two acids differ. This experiment occurs through organic synthesis, meaning in order to create the desired product, the starting material must be chemically modified. The first step of the experiment was to reflux methyl salicylate with

“history”) This is relatable as the bark and leaves of the Willow tree are a natural resource of the Salicylic acid, which is found in Aspirin, which made the patients feel better while healing them, similar to the modern Aspirin. Further along in Human history we know that Edward Stone discovered and isolated the key chemical in the Willow bark/leaves called Salicylic Acid. The problem with the Salicylic acid was that it was extremely tough on stomachs and could cause nausea and vomiting, hence the next

of this experiment was to prepare acetylsalicylic acid, which is aspirin, investigate two of its chemical properties, and measure the purity of the synthesized aspirin. The aspirin was created in an esterification reaction between salicylic acid and acetic anhydride. Using the aspirin that was made from salicylic acid and acetic anhydride, it was tested to see if the salicylic acid in the aspirin acts as a phenolic alcohol or as a carboxylic acid by adding FeCl3 solution. Procedure A boiling-water

room temperature is not enough to overcome the activation barriers and eventually form a product. This is due to the initial material being less thermodynamically stable than the product; in this case, methyl salicylate was less stable than the salicylic acid. Heating was performed under reflux7. In this experiment, the reagent that was fully used when the reaction completed and limited the amount of product formed was the methyl salicylate, making it the limiting reagent. Determining the theoretical

what was said by the company. In other words, the Bayer Aspirin did not contain 325mg of ASA, instead it actually contained 283mg. The percent purity of ASA was calculated to be 65.0 % and based on the reaction table, the limiting reagent was salicylic acid and manipulations were made with the actual and theoretical yield which gave an overall percent yield of 53.4%. Furthermore, since this value is less that 100%, it is considered to be a small percentage yield, this is an indication that the actual

organic molecule of acetylsalicylic acid using a back-titration method. The objectives of the experiment were achieved by synthesizing the organic molecules of acetylsalicylic acid (using salicylic acid and acetic anhydride), and methyl salicylate (using salicylic acid and methanol). FeCl3 was added to each synthesized product to test for the presence of a hydroxyl group (—OH). FeCl3 reacts with a hydroxyl group to form a brightly coloured magenta

This experiment explored the multi-step synthesis of synthesis acetylsalicylic acid commonly known as aspirin. A common procedure used in organic chemistry labs is multi step synthesis. this procedure involves a cascade of reactions that ultimately lead to a desire product. The series of reactions begins with commonly found or readily available reagents which are synthesized into products which can be used for a secondary reaction, and so on and so forth until the final desired product is synthesized
