Gamido‚ Mitchiko Mariel M. Mizukami Abstract Acetylsalicylic acid‚ or also known as aspirin is known to be a drug that relives people of pain and is commonly used even today. It is synthesized from salicylic acid and ethanoic anhydride‚ both of small quantities. Phosphoric acid was used as a catalyst in the synthesis to speed up the process. Esterification is involved and the final product is aspirin with the presence of acetic acid as the byproduct. In order to create the powder form of aspirin

EXTRACTION OF BENZOIC ACID‚ 2-NAPHTHOL‚ AND NAPHTHALENE FROM UNKNOWN SAMPLE # 131 Douglas G. Balmer (T.A. Mike Hall) Dr. Dailey Submitted 11 July 2007 Introduction: The purpose of this experiment was to separate a sample of benzoic acid‚ 2- naphthol‚ and naphthalene of unknown proportions using a two-base extraction method. The three components of the mixture will react differently to sodium bicarbonate and sodium hydroxide because each of the bases’ conjugate acids has a different pKa. The

Acid-Base Extraction: Separation of an Organic Acid‚ Base and a Neural Compound Introduction/Background Acid base extraction is a widely used commercial method in separating acids‚ bases and neutral compounds. This is concept is based on several physical properties of the compounds‚ such as boiling point‚ melting points and solubility. The different solubility properties of the protonated and non-protonated forms of these compounds depend on the functional groups present‚ such

Experiment #5: Acid Burn!!! Introduction The goal of this lab was to correctly prepare a 0.2M solution of NaOH‚ identify highly acidic household cleaning chemicals‚ and determine their concentration (molarity) through titrations using the previously prepared 0.2M NaOH solution. Experimental First‚ to create 0.5L of 0.2M solution of NaOH‚ standard 3M NaOH solution was obtained. Next‚ calculations were performed to determine the amount 3M NaOH necessary to create 0.5L of the 0.2M solution and‚ as

British mercantilism established itself with the help of the trans-Atlantic trade. Great Britain was then able to have adequate supremacy over the colonies to impose several acts such as the Navigation Acts and Molasses Act. Trade routes linked the American Colonies‚ West Indies‚ Africa and England. England‚ being the mother country‚ wanted a favorable balance of trade. The triangular trade is an example of mercantilism‚ or the idea that the mother country gains wealth and power by controlling
