This experiment focuses on the concept of electrophilic aromatic substitution‚ which is a type of benzene reaction. This reaction consists usually of benzene and an electrophile. The role of the nucleophile is played by the double bond on the benzene ring. IT will react will the electrophile and this reaction will form a carbon cation intermediate. With additional reactions with a base‚ the electrophile fundamentally replaces the hydrogen of the benzene. Benzene is classified as one of the countless

Panacetin contains sucrose‚ aspirin and an unknown which can be acetanilide or phenacetin in which phenacetin was created and weighed. Introduction In this lab our basic goal was to make the sucrose‚ aspirin and unknown that are formed from pharmaceutical panacetin. In doing this lab we used NaOH and diethyl either‚ along

color change or a warming effect. Flammability was tested by igniting 3-5 drops of the sample in a small evaporating dish. Baeyer’s test and Bromine test were used for tests for active unsaturation. Aromaticity of the compound was determined through nitration. Oxidation was tested by introducing 8 drops of 2% KMnO4 solution and 3 drops of 10% NaOH solution to 4 drops of the sample organic compound in a test tube and warming the mixture through water bath. All of the test compounds are liquid and colorless

The objective of this lab was to identify an unknown compound by determining the melting point range using fast and slow ramps. Also‚ to determine the eutectic point of Urea and Cinnamic Acid. An unknown compound that was numbered 8 was chosen. A small amount of the unknown compound was placed in a weighing paper using a spatula. The weighing paper was folded in half twice and then was grinded using a spatula. After the unknown compound was grinded about 1-2mm was added into a capillary tube. A

Sulfa Drugs: Preparation of Sulfanilamide Introduction The purpose of this experiment is to prepare sulfanilamide from p-Acetamidobenzenesulfonyl chloride. This will be done using reflux‚ vacuum filtration‚ and melting point determination. Experiment Scheme6 Figure 1. Reaction equation.6 A hot water bath was prepared in a fume hood using a 250-mL beaker. 2.5 g of p-acetamidobenzenesulfonyl chloride was placed into a 50 mL Erlenmeyer flask and 11 mL of dilute ammonium hydroxide solution

To get to aniline‚ tin metal acts as a reducing agent and is oxidized to SnCl4. The purification of crude aniline is done by distillation and extraction. Aniline can be converted to acetanilide by acetylation reaction using acetic anhydride with sodium acetate. This step protects the amine functional group from doing unwanted reactions during chlorosulfonation and amination steps. The chlorosulfonyl group attacks in the para position

Separating The Components of “Panacetin” Observations Most natural products and many commercial preparations are mixtures containing a number of different substances. To obtain a pure compound from such a mixture‚ you must separate the desired compound from the other components of the mixture by taking advantage of differences in their physical and chemical properties. Acidic or basic substances are often converted to water-soluble salts‚ which can then be separated from the water-insoluble

2-(2‚4-Dinitrobenzyl) pyridine Peter Defnet and Cody Krepps Department of Chemstry Juniata College Huntingdon‚ PA September 18‚ 2012 Abstract: Nitration of 2-benzylpyridine is supposed to yield 2-(2‚4-Dinitrobenzyl) pyridine‚ when electrophilic aromatic substitution is the mechanism. Experiencing many pitfalls‚ however‚ has lead to the actual product obtained to contain the expected product‚ as well as many impurities. This report examines the supposed mechanism for the electrophilic substitution

Explosives A chemical explosive is a compound or a mixture of compounds susceptible of a rapid chemical reaction causing a quick physical outburst of gases or heat radiation. The first explosives were created by the Chinese in the 11th century. These were mixtures of nitrate salts‚ sulfur and charcoal‚ now known as black powder. Gunpowder which is a low explosive‚ exhibits deflagration‚ or rapid burning‚ rather than detonation‚ the reaction exhibited by high explosives. While‚ perhaps counterintuitively
