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

Classification Tests for Carboxylic Acid and Derivatives Mary Catherine Sarte‚ John Emmanuel Sy‚ Allurie Umel‚Franklin Yap‚ Mary Christine YouIntroduction Carboxylic acids derivatives are simply groupsof compounds that contain a carbonyl group butwith an electronegative atom attached to thecarbon. The difference in the structure leads to amajor change in reactivity. The reactions of thesegroups of compounds involve nucleophilicsubstitution. Although there are abundant kindsof carboxylic acid derivatives

preparation Panacetin‚ a proposed type of pain-killer. Panacetin is typically made up of sucrose‚ aspirin‚ and acetaminophen‚ but the third component in this experiment is unknown. The unknown component is suspected to be a chemical relative of acetaminophen‚ either acetanilide or phenacetin. Using techniques such as extraction‚ evaporation‚ and filtration‚ the three components will be isolated based on their solubilities and acid-base properties. The percent composition of Panacetin will also be deduced

Premium Carbonyl Ester Carboxylic acid
Phenol‚ also known as carbolic acid‚ is an aromatic organic compound with the molecular formula C6H5OH. It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (-C6H5) bonded to a hydroxyl group (-OH). It is mildly acidic‚ but requires careful handling due to its propensity to cause chemical burns. Phenol was first extracted from coal tar‚ but today is produced on a large scale (about 7 billion kg/year) from petroleum. It is an important industrial commodity as a
