suppository to use rectally. Extended release tablets should be taken with a full glass of water and cannot be broken‚ crushed‚ or chewed. It is recommended that delayed-release tablets should be taken with water but they can take time to work so tablets should not be taken if pain needs to be relieved quickly. Chewable aspirin can be chewed‚ crushed or swallowed whole but after being consumed the consumer should drink full glass of water. There are many uses for Aspirin. Prescription Aspirin is used to

Fragments of Kennedy’s skull are being gathered by Jackie‚ and the crowd is in awe. The president is dead. Lee Harvey Oswald‚ an employee at the depository‚ is arrested an hour after the killing. He can never defend his case because two days later Oswald is killed by Jack Ruby. Almost immediately

Aspirin Synthesis Introduction Out of all the pharmaceutical drugs in the worlds‚ aspirin is made the most. Any potential pharmacist must be familiar with synthesizing the drug. The goal of this lab is to synthesize as much pure aspirin as possible. The reactants‚ acetyl anhydride and salicylic acid‚ must react in phosphoric acid. With phosphoric acid as a catalyst‚ the reaction yields aspirin and acetic acid. The equation for the reaction is as follows: “(CH3CO)2O + HOC6H4COOH □(→┴yields ) CH3CO2C6H4CO2H

Analysis – Synthesising Aspirin results After recrystallisation differences between the crude and purified aspirin were noted. The impure (crude) aspirin was powered and fluffy with small clumps and was slightly yellow in colour whereas the pure aspirin has a less fluffy crystalline powder and was whiter. This showed distinct differences in the two substances but similarities were also apparent showing aspirin‚ in some level‚ was created. Before recrystallisation the crude aspirin could of included

to synthesise acetylsalicylic acid (aspirin) by creating a reaction between acetic anhydride and salicylic acid. This was be accomplished through the use of recrystallization. Acetic anhydride and salicylic acid are mixed together‚ and then acidified by the addition of a few drops of concentrated sulfuric acid‚ which catalyzed the reaction. The percent yield is calculated to determine the effectiveness of the reaction in preparing the desired product (aspirin). The limiting reactant of the equation

Prior to the 1800’s‚ willow bark was often brewed into a tea‚ or chewed to relieve pain. While the salicylic acid is effective at reducing pain it was found to irritate the lining of the stomach. It was mostly by chance that on August 10‚ 1897 Felix Hoffmann‚ a German chemist who obtained

Synthesis of Aspirin (Acetylsalicylic Acid) Abstract: This experiment is about the synthesis of aspirin under laboratory conditions. Aspirin is prepared by reacting salicylic acid and acetic anhydride; in the presence of sulfuric acid. After fully dissolving the salicylic acid with acetic anhydride‚ the solution is cooled and cold water is then added. Once the crystals form they are then filtered and left to dry out. There mass is measured and recorded then the yield is calculated. Introduction:

anhydride is an irritant and also flammable‚ therefore gloves and goggles should be worn at all times during the experiment. It is reactive to water‚ so in the case of fire‚ alcohol foam or carbon dioxide is preferred to use as an extinguisher. This chemical has harmful fumes and use of a fume hood is strongly recommended.
