ASPIRIN (acetylsalicylic acid) from SALICYLIC ACID
1 Acetylsalicylic acid: method 1.2
Phenols, unlike amine, cannot be acetylated satisfactorily in aqueous solution: acetylation proceeds readily with acetic anhydride in the presence of a little concentrated sulphuric acid as catalyst.
Experiment V02 An analysis of aspirin tablets
a. Weigh accurately a definite number of aspirin tablets (two or three tablets weighing no more than 1.5 g) into a 250 cm3 conical flask. Initiate the hydrolysis of the aspirin by adding 25 cm3 of 1.0 M sodium hydroxide by...

#15 Synthesis of Ethyl Salicylate from Salicylic Acid
Purpose: Salicylic acid is converted to the liquid ethyl salicylate by addition of ethanol.
Yields of salicylic acid (week 1) and ethyl salicylate will be found, a...
Protein synthesis is one of the most fundamental biological processes. To start off, a protein is made in a ribosome. There are many cellular mechanisms involved with protein synthesis. Before the process of protein synthesis can be described, a person must know what proteins are made out of. Th...
This report involves a well description on acid rain as well as a focus on acid rain in eastern Canada. This report contains a very helpful basic background on acid rain as well as a questionnaire. It involves an annual report on the Federal-Provincial Agreements, sulphur dioxide emiss...
The Expression of a Gene
The process of Protein Synthesis involves many parts of the cell. Unlike other similar productions, this process is very complex and precise and therefore must be done in proper sequence to work effectively. The slightest error during this process co...
Abscisic Acid and Stomatal Closure
Abscisic acid is a single compound unlike the auxins, gibberellins, and cytokinins. It was called "abscisin II" originally because it was thought to play a major role in abscission of fruits. Though ABA generally is thought to play mostly inhibitory roles, it ha...
Multistep Synthesis of Tetraphenylcyclopentadienone
In this laboratory experiment a synthesis was performed through several separate steps. The purpose of the experiment was to synthesize tetraphenylcyclopentadienone from benzaldehyde and to run reactions on carbonyl containing com...
RUNNING HEAD: Synthesis of Banana Oil
A reflux apparatus was assembled with a water-cooled condenser and a drying tube. Isopentyl alcohol, glacial acid sulfuric acid is added to a 25 milliliter round bottom flask and attached to the reflux apparatus. The mixture was boiled, the extracted...
Synthesis of a Porphyrin
Porphyrins are hetereonuclear, macrocyclic compounds that play an important role in living organisms. Examples include the non-protein heme portion of hemoglobin in animals whereby the lone pairs on nitrogen can bind to the oxygen-carrying iron. In plants, chl...
Grignard Synthesis of Triphenylmethanol from Benzophenone
Purpose: The purpose of this experiment was to synthesize the tertiary alcohol triphenylmethanol from a Grignard reagent, phenyl magnesium bromide. The Grignard reagent was synthesized from bromobenzene and magnesium and then reacted wit...
An account of amino acid metabolism disorders in humans beings with an emphasis of the underlying molecular defects
Amino acids are monomers which join together to form a protein and are multi-functional in the human body. However, defects in amino acid metabolism occur which cause a numerous amo...
PROTEIN STRUCTURE AND SYNTHESIS
Proteins are polymers of a-amino acids. There are twenty amino acids that are commonly found in proteins. Each amino acid has a similar, yet unique structure. Almost all of the amino acid have a carboxyl group and an amino group. At neutral pH the natural amino acids...
Solid Phase Peptide Synthesis (SPPS)
Solid phase synthesis is a process in which synthetic reactions are carried out on a solid support. The idea was developed by R .B. Merrifield to synthesise polypeptides and this work earned him the Nobel Prize in 1984.
Solid phase synthesis can...

Synthesis of Chloroform
With Calcium Hypochlorite and Acetone
When chlorine is passed into boiling alcohol, both chlorination of the methyl group and oxidation of the primary alcohol group to an aldehyde occur, g...
