Experiment 1: separating components of a counterfeit pharmaceutical Aim Counterfeit pharmaceuticals are a big concern regarding the issue of medicines due to fake versions containing either the wrong ingredients or inaccuracy of the active ingredient which can cause toxicity issues in patients using these products. The aim of this experiment

2-naphthol‚ and naphthalene. These organic solids are purified by partitioning the solid in 2 immiscible solvents‚ diethyl ether and sodium bicarbonate or sodium hydroxide. II. Significance a. The significance of the Extraction lab is to purify Acetanilide benzoic acid‚ 2-naphthol‚ and naphthalene by determining the partition coefficient. This value is determined by dividing the solubility of the given solute in the extraction solvent (Sodium bicarbonate or Sodium hydroxide)) by the solubility in

properties. To obtain such a pure compound‚ the compound we want must be separated from its other natural components‚ which can be done by manipulating physical and chemical properties. 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

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

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

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

Introduction Carboxylic acids is an organic compound that contains a carboxylic group(-COOH). Its general formula is R-C=OOH with R referring to the rest of the molecule such as H and C. They are directly attached to a carbonyl group and the interaction between them affects the reactions of each. The polarity of the O-H bond

Contents 1.0 Abstract Acetaminophen and aspirin are both well-known drugs that relieve pain and reduce fever. This report looks at acetaminophen as a potential substitute for a patient who is allergic to aspirin. Acetaminophen‚ a common analgesic drug that can be bought over the counter‚ was synthesised by Hormon Northrop Morse. With acetaminophen consisting of a benzene ring‚ an amide and an alcohol group‚ it has the ability to stop pain and reduce fevers. However‚ due to the state of technology
