(Richman‚ 2004). It also has very low toxicity is it is used properly. Acetaminophen is cheap and easily obtainable from any pharmacy. Acetaminophen is created when the amine group of p-aminophenol is acetylated by acetic anhydride. This creates an amide functional group and the by-product of this reaction is acetic acid. The crude acetaminophen will form as a white solid after the acetylated reaction. To turn this crude acetaminophen into a purified form‚ the recrystallization technique will be used

Abstract Introduction The acylation of the α carbon position of a carbonyl group is one of the greatest breakthroughs that has benefited chemists in organic synthesis particularly when in need of building a carbon skeleton of interest in a molecule. For one to be able perform this acylation technique‚ there are two mar approaches which are employable. The first method involves the deprotonation of the α-Carbon atom which has a pKa known to be ̴20 through the use of a strong base for instance

E. Reactions of Aldehydes and Ketones with Sodium Hydroxide Objectives: To know the reactions of aldehydes and ketones with sodium hydroxide a) State the function of Sodium Hydroxide in the test. Sodium hydroxide (NaOH) is the oxidizing agent. b) What are the principles involved in the test? What is its purpose? Cannizzaro reaction is a reaction that uses a strong base‚ such as sodium hydroxide‚ which results to the formation of a carboxylic acid (or its corresponding salt) and an alcohol

Syneresis - the process by which a liquid is separated from a gel owing to further coagulation Saturated fat: It comes mainly from animal food products at a normal room temperature. HDL cholesterol: Lipoproteins‚ which are combinations of lipids (fats) and proteins‚ are the form in which lipids are transported in the blood. HDL cholesterol is considered the "good" cholesterol. The higher the HDL cholesterol level‚ the lower the risk of coronary artery disease. Triangle test- A sensory-based

INTRODUCTION The purpose of this experiment is to synthesize trans-9-(2-phenylethenyl) anthracene from benzyltriphenylphosphonium chloride and 9-anthraldehyde through the reaction mechanism recognized as the Wittig Reaction. The Wittig Reaction allows the chemist to synthesize phosphoranes in the lab with relative ease. A more recent and inexpensive version of the reaction is the Wittig-Horner reaction (1). ABSTRACT Georg Wittig was a German chemist and Nobel Prize winner in 1979 for the Wittig

Introduction Esters derive from the reaction between a carboxylic acid and an alcohol (Figure 1). Figure 1. The General Reaction Equation of Ester Formation From A Carboxylic Acid & An Alcohol. Carboxylic acids contain the functional group –COOH whereas in ester’s the hydrogen is replaced with an R denoting any alkyl or aryl group; -RCOOR’. Esters with low-molecular weights are commonly used as components in the flavor’s and odors of many fruits & fragrances’ as well as to enhance foods & beverages

Hydrocarbon Derivative: Amines Amines are a type of hydrocarbon derivative‚ and they are used in many ways in society. Several companies use amines in products such as drugs and medicines. Also‚ in nature‚ amino acids help the body make proteins‚ and amines are found in many vitamins. For example‚ DOW Chemicals “plays an important role in commonly used products found around the world” by using amines in the manufacturing of energy drinks‚ detergents‚ insulin‚ etc. This is a very large industry
