EXERCISE 11 Synthesis of Aspirin (Acetylsalicylic Acid from Salicylic Acid) RAQUID‚ Rency J Group 5 18L I. Introduction Due to the demand of certain reagents in the laboratory in order to perform and conduct further experiments or produce essential compounds‚ chemists continuously develop organic synthesis. This process aims to prepare and synthesize desired organic compounds from commercially or readily available ones by providing the simplest route in synthesizing the compound

follows a semi microscale technique even a small amount of lost product yields a great loss in the yield 4. These sources of error could be minimized by doing a larger reflux in order to increase the yield. However‚ as the purpose was to simply synthesis SnI4 in order to identify the stable oxidation states (the melting point range requires very little product) it would be advantageous to use the current method. This is due to the smaller quantity of materials needed for this type of reflux‚ thus

Grignard Synthesis of Tirphenylmethanol David Szuminsky Organic Chemistry Lab II Shaopeng Zhang Monday 1PM 2/10/14 & 2/24/14 - Abstract A sample of triphenylmethanol was prepared using Grignard synthesis techniques. Reflux was used in order to speed up the reaction and the final product was purified using recrystallization methods. The percent recovery and percent yield were 80.46% and 47.526%‚ respectively. A melting point range of 85-87oC was obtained from

The acetic acid mixed with acetaminophen created an impure sample‚ which was purified through the addition of a water/methanol solution. The percent recovery of acetaminophen from the impure sample to the pure

Six (6) mice were randomly selected and grouped into 2 groups and were given extracts from the fruit of Abelmoschus esculentus (EA)/okra which was chopped into three pieces and was soak in 250ml potable water overnight. 1st group is the Control Group and the 2nd group is the Treatment Group. Average results of the two (2) groups are determined and recorded upon conducting this experimental research. The Control Group has an average result

It should be noted that direct comparision between these immigrants and the native population is impossible‚ mostly due to the different socio-political factors surrounding each population. That is why the study compared different demographics between immigrants and refugees from the same origin. There were five areas of origin for the majority of these refugees: Afghanistan‚ Iraq‚ Iran‚ the Middle East‚ Somalia‚ and former Yugoslavia. Another factor to keep in mind are the inherent biases that

Purpose Acetophenetidin can be formed through two methods‚ Williamson ether synthesis and amide synthesis. By working in groups of two we were able to complete both methods of synthesis routes. The end result should be the synthesis of a similar product‚ by verification between the two individuals. Reaction Experiment and Observations Amide Synthesis of Acetophenetidin The Synthesis reaction began by removing the colored impurities from the p-phenetidine‚ accomplished by mixing

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:
