Acid-Base Strengths of Organic Compounds By: Chris Frankmore Due Date: February 15‚ 2011 Resonance Benzenesulfonic Acid Benzoic Acid Benzyl Alcohol Benzylamine P-Cresol P-Toluidine Acid/Base | Structure | pH | Why It is a strong/weak acid/base | Benzenesulfonic Acid | | 1 | This is a strong acid because it has a pH of 1. Another reason why this is a strong acid is that its conjugate base has strong resonance stabilization

adopting new technologies and are using feed acidifiers for supplementing the diets of animals. The market value of propionic acid as a feed acidifier was the highest in 2012‚ and is projected to grow with the increasing demand for feed acidifiers in the livestock industry. The benefits of feed acidifiers are leading the market demand in the feed industry. The fumaric acid market is comparatively small and is projected to grow at a CAGR of 5.8% from 2013 to 2018. The feed acidifiers market is projected

ETHERS Classification of Ethers: Symmetrical ethers – two groups attached to O are identical Ex. CH3CH2OCH2CH3 – diethyl ether Unsymmetrical ethers – two groups attached to O are not identical Ex. CH3CH2OCH3 – ethyl methyl ether Physical Properties of Ethers: Ethers have much lower boiling points compared to alcohols of comparable MWs. BPs of ethers increases with increasing MW. BPs of isomeric ethers increase with increasing alkyl chain length. BPs of ethers are about the

EXERCISE 11 Synthesis of Aspirin (Acetylsalicylic Acid from Salicylic Acid) RAQUID‚ Rency J Group 5 18L I. Introduction Due to the demand of certain reagents in the laboratory in order to perform and conduct further experiments or produce essential compounds‚ chemists continuously develop organic synthesis. This process aims to prepare and synthesize desired organic compounds from commercially or readily available ones by providing the simplest route in synthesizing the compound

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

Synthesis of Isopentyl Acetate (Banana Oil) Using a Fischer Esterification Reaction Zhenshu Wang (Stan) TA: Aaron League September 23‚ 2012 Purpose: The purpose of the experiment was to perform the acid-catalyzed Fischer Esterification of acetic acid and isopentyl alcohol to form isopentyl acetate‚ or banana oil‚ which is used in flavor industries. The equilibrium of the reaction was changed by adding an excess amount of acetic acid. The reaction was refluxed and product was purified by extraction

A. Title – Acid-Base Extraction with Separatory Funnel B. Introduction – The main objective of the experiment was the extract an acid‚ a base‚ and a neutral compound from a 2:1:1 compound of benzoic acid‚ p-nitroaniline‚ and azobenzene. In theory‚ an extraction technique based on phase distribution should allow two immiscible solvents to separate with a portion of the solute distributed into each. Using a separatory funnel‚ acids were extracted with bases (NaOH)‚ and bases were extracted
