The crude acetaminophen was expected to be dark in color. This was due to the fact that the impurities were formed from oxidation of the starting phenol. The intensity of this was enough to impart color to the crude acetaminophen.…
All the reagents and solvents used for synthesizing the title compound were of Analar grade (Merck) and were used as such without further purification. The 2-naphthol derived Mannich base 1-((4-methylpiperazin-1-yl)(phenyl)methyl)naphthalen-2-ol (MPN) was synthesized according to the general procedure described in the literatures [13, 14]. The 2-naphthol (4.33 g, 0.03 mol) was dissolved in 30ml of ethanol and it was mixed with…
The final compound which I am going to look at is 4-aminobenzenecarboxylic acid. The compound is also known as 4-Aminobenzoic acid. The molecular and structural formula of the compound is C7H7NO2 which means that the compound consists of seven carbon atoms attached to seven hydrogen atoms along with one nitrogen atom and two carbon atoms attached as a carbon-oxygen double bond. The displayed formula for the 4-aminobenzenecarboxylic acid compound is shown and it shows the formula in a ring form therefore means that the compound is an aromatic compound. This is an aromatic compound because the compound consists of six carbons of benzene joined in a ring, having the planar geometry of a regular hexagon in which the distance between all of the C-C bonds are equal.…

The experiment did not contain any form of reaction mechanism since no chemical identity had been changed. The lab demonstrates the use of chemical molecular behavior to isolate a particular set of molecules. Caffeine had already existed in the leaf itself but needed to be separated from the other chemicals. Caffeine’s chemical structure is relatively similar to the nucleic acid purine in that they use nitrogen and is bicyclic but lacks an alkene, amine and an amide. Caffeine has a solubility of 67.0 g/100 mL in boiling water but tannins also boil in hot water to form catechin. Catechin cannot react with water but it can with calcium carbonate. The calcium carbonate was added into the reflux beforehand so the catechins can quickly change to form glucose and salts of gallic…
Although the acetanilide and aspirin are both quite insoluble in water at room temperature, the sodium salt of aspirin is very soluble in water but insoluble in dichloromethane. Because aspirin is a reasonably strong acid, it can be converted to the salt, sodium acetylsalicylate, by reaction with the basic sodium hydroxide. While the two layers are thoroughly mixed, the aspirin will react with the sodium hydroxide in the bottom layer, which then migrates to the aqueous layer and can be easily separated in a separatory funnel. Adding some dilute hydrochloric acid to the aqueous solution restores free aspirin as an insoluble white solid; evaporating the solvent from the bottom layer leaves the acetanilide behind.…
TRANSCRIPTION: Transcription is the process of which DNA matches corresponding RNA bases, Transcription is located in the Nucleus, and the only type of RNA that is involved in Transcription is mRNA, and the purpose is so that the code can get out of the Nucleus, mRNA is also made through Transcription, It also takes information that doesn't directly make proteins but it helps makes codes for the production of proteins, DNA Transcription consist of 4 nucleotide bases, Adenine, Thymine, Cytosine, Guanine. Transcription also unwinds the strand of DNA and the RNA comes in and matches then becomes a single strand. The only thing that changes during this process is the Thymine gets replaced with Uracil.…
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.…
In order to first perform the reaction, 1.5 mL of 4-methylcyclohexanol was added to a pre-weighed 5mL conical vial. The conical vial was then weighed to find the actual mass of 4-methylcycloheaxanol. Then, 0.4mL of 85% phosphoric acid was added to the conical vial using a plastic pipet. Six drops of concentrated sulfuric acid was then added to the vial using a glass pipet. A spin vane was then added before adding the Hickman head, water condenser and a drying tube packed with calcium chloride to the conical vial.…
Purpose: The purpose of this experiment is to synthesize Isopentyl Acetate using a Fischer esterification reaction. Fischer esterification is an acid-catalyzed condensation of an alcohol and a carboxylic acid, yielding an ester and water. Isopentyl Acetate has the scent of banana oil, once synthesized it will be purified by distillation. Then the analysis of the sample using H NMR and IR will determine purity of the product.…
Small samples of acetaminophen, acetylsalicylic acid, cellulose, starch, and caffeine were obtained. These samples were then placed into seperate sets of test tubes that contained water, acetone, or dichloroethane. Solubilities were then tested for each sample in each solution which can be seen in Table 5. Next, four random pills were obtained and weights were taken of each. Each of the pills were grinded up using a separate mortar and pestle.…

Aspirin is known as a pain reliever for muscle ache, head ache and can prevent heart attacks as well as blood clots, and many more things that it can help with. Aspirin is known as Acetylsalicylic acid (ASA) is a Salicylate. Salicylates are organic acids from plants that people for hundreds of years have been used for pain reducing. Salicylic acid irritates the stomach when consumed so German scientist Felix Hoffman suggested ASA as an alternative. Aspirin is made when Acetic Anhydride reacting with Salicylic acid to produce Acetylsalicylic acid and Acetic acid (diluted vinegar). Aspirin is in millions of home today and in America, about 50 million tablets are consumed every day. When aspirin ages it breaks down and returns to the main chemicals that made the reaction.…
