Synthesis of Phenols You can prepare phenols in large quantities by the pyrolysis of the sodium salt of benzene sulfonic acid‚ by the Dow process‚ and by the air oxidation of cumene. Each of these processes is described below. You can also prepare small amounts of phenol by the peroxide oxidation of phenylboronic acid and the hydrolysis of diazonium salts. Pyrolysis of sodium benzene sulfonate In this process‚ benzene sulfonic acid is reacted with aqueous sodium hydroxide. The resulting salt

INTERCHAPTER S Synthetic Polymers The formation of nylon by a condensation polymerization reaction at the interface of water and hexane‚ two immiscible solvents. The lower water layer contains the compound hexanedioyl dichloride‚ Cl C(CH2)4C O O Cl hexanedioyl dichloride The reaction produces nylon and HCl(aq). The polymer forms at the interface between the two solutions and is drawn out as a continuous strand. University Science Books‚ ©2011. All rights reserved. www.uscibooks.com

CLASSIFICATION TESTS A. Acids There are relatively few suitable tests for carboxylic acids. Classification is based mostly upon solubility tests. If the compound is water soluble‚ test the aqueous solution of your compound with pH paper (also check the pH of the original water). If the compound is water-insoluble and it dissolves in 5% (1.5M) sodium hydroxide and 5% NaHCO3 solutions as performed in your solubility tests‚ it can be classified as a carboxylic acid. Establish an equivalence value

INDUSTRIAL ANIMAL AGRICULTURE 1. Some definitions: What is ‘industrial animal agriculture’‚ and what are its properties? What are zoonoses? Industrial animal agriculture is a modern form of intensive farming that uses intensive production lines and is designed to produce the highest output at the lowest cost. Industrial farms use new technology which provides them with high mechanisation‚ speed in production and low labour requirements. The animals in industrial farms are kept usually indoors with

PRODUCT Pectin for use in food is defined as a polymer containing galacturonic acid units (at least 65%). The acid groups may either be free‚ combined as a methyl ester‚ or as sodium‚ potassium‚ calcium or ammonium salts‚ and in some pectins amide groups may also be present. It is produced commercially as a white to light
